Beaglebone Black Devkit BeagleBone Rev C

All other things were Ok, but it did not work just right out of the box. I had to download the latest image and flash it on eMMC. I would expect the default build to work for basic tasks, but it did not (e.g. not even LED blinking worked out of the box). After flashing the new image though it is working fine. Am exploring more. Find it interesting. I have been a Raspberry Pi user for some time, so will know in sometime how this SBC is in comparison.

Quality is very good and delivery time was reasonable.

the product is good

If you are looking for an alternative to the Raspberry Pi, keep looking. The software is simply not mature enough to be called suitable for generic use by the average Joe.The USB Ethernet interface decided to take the IP address already used by my Linux PC instead of the one in the documentation.There is a gaping security hole by default, people can ssh as root to the beaglebone without entering a password. I didn't see this mentioned anywhere in the online documentation, just the account for user 'debian'.The desktop feels really underpowered. I started a vnc server on the BBB and connected to it from my PC (using the same network switch). The desktop menu really struggled to keep up although it's supposed to be lightweight.The javascript programming facility on the board's web server didn't seem to work either. The system logs showed a lot of errors while trying to access I/O pins.Trying to update the software using apt returns an error because there are broken package dependencies.And updating the software by downloading an image requires a memory card which is not included.Having said that, the board supports mDNS out of the box, which makes it easy to find it by pinging "beaglebone.local".The hardware seems quite impressive. CAN, SPI, I2C, GPIO, Ethernet, USB (host+client), PWM, HDMI, JTAG... lots of stuff.In short, this board seems to have been designed with hardware in mind. If you want to use it for embedded projects it seems to be a very good choice (I haven't started using mine yet though, so I cannot tell from personal experience). If you want something to replace your generic Raspberry Pi you might be disappointed.

this is an excellent little single-board computer (SBC); the ARM CPU has really come a long way and now provides a great hardware platform for experimenting and prototyping...first, i highly recommend getting Prof. Molloy's Beaglebone booknext, your first accessory, even before a case or microsdhc card, should be an Adafruit FTDI UART USB serial cable to plug into the serial debug header pins on the BBB's topside... run your favorite terminal app (i use Zterm on the mac: 1152008N1; if you use minicom under Linux - HINT: turn off hardware handshaking!)i plugged Adafruit cable into my BBB, fired up Zterm on my Mac, then applied power via the mini-USB port... you can then watch the boot process... login as 'root' and press Enter - no password required..the Debian distro installed on the eMMC is from Oct. 2015 - obviously needs upgrading, but good enough for my initial purposes...i also have a Beaglebone Green Wireless (BBGW)... have been very pleased with that SBC as well... wifi and Bluetooth onboard with four USB 2.0 ports makes life easierhowever, i like the BBB due to its companion book by Molloy (who has also just released a similar book for the Raspberry Pi 3)...will the BBB last in the marketplace? who knows? at this point, credit must be given to a singularly talented individual who has contributed untold hours and effort to the Beaglebone family: Mr. Robert Nelson of DigiKey - you'll find weekly new releases you can flash onto the eMMC or boot via the miniSD card port (my BBGW is dual-boot)btw, it was very easy to port support for SSD1306 128x64 OLEDs to the BBGW, and i'm sure the BBB would be the same... my Beaglebone provides a readout of:- date, time of day- IP address- free memory- free SD card storage- uptime- wifi signal strength- local weather conditionsTIP: download the file 'BeagleBonePinGuide.pdf' then print it out, cut the images, then cover both sides with tape, and then tape or glue onto the side of P8 and P9 - you'll have a handy guide to the pins - for the life of me, i don't know why the Beaglebone folks didn't pick up a clue from the Arduino folks, who screen print the numbers on the PCBs (take a look at an Uno R3) - seriously simple and stupid, eh?anyhow, you'll like this little computer - it comes with a USB cable but you'll want to find a barrel-connector power supply...what can you do with this computer? well, you're limited only by your imagination... i have my BBGW already working as a printer server, a media server, etc.. you may want to craft a home-security system or home environmental alarm...

I've bought 4 of the BBB rev C boards over the last few months from three different vendors. Three boards are the same mfg - Circuitco. The other is Element14. They have all worked the same except for a small difference with Element14 which I'll mention later.It includes a USB cable (mini to standard-A). With the cable you can power it from any USB source such as a PC/laptop or an A/C adapter used by for cell phones. Beware it's a mini-USB connector on the BBB and most android phones are micro-USB, so pull the cable out of the phone A/C adapter if you can, and use the BBB cable. The other option is a dedicated A/C to 5VDC adapter with a barrel plug (https://www.amazon.com/gp/product/B00FA7DLE0). Also pick up a micro-hdmi cable to connect to a monitor.There are lots of warnings to power it off carefully. For example from the window manager, or "shutdown -h now" from a terminal window, or press the power button once and let it power off.It's a 1GHz processor and has a few power modes, normally running as low as 300MHz so it's quite cool to the touch. If you're a power user you can force it to 1GHz but maybe want to add active cooling. If it's in a case or restricted air flow that might be a problem. At the default setting it seems very fast.It should come up on Ethernet using DHCP, when you get to that point it's easy to upgrade to the latest Debian software:sudo apt-get updatesudo apt-get upgradeOn the Element14 board, first fix a whacky OS issue before trying to upgrade. Look in /etc/init.d. If you see a file called "led_aging.sh" then you almost surely have the Element14 board as the Circuitco ones don't have this. Edit that file (/etc/init.d/led_aging.sh) and make sure it looks like this:#!/bin/sh -e### BEGIN INIT INFO# Provides: led_aging.sh# Required-Start: $local_fs# Required-Stop: $local_fs# Default-Start: 2 3 4 5# Default-Stop: 0 1 6# Short-Description: Start LED aging# Description: Starts LED aging (whatever that is)### END INIT INFOx=$(/bin/ps -ef | /bin/grep "[l]ed_acc")if [ ! -n "$x" -a -x /usr/bin/led_acc ]; then /usr/bin/led_acc &fi

The major improvements are that the Debian rather than the Angstrom Linux distribution is used and that this is now pre-installed on the 4 GB eMMC flash memory. No longer must the operating system be installed as a system image on a micro SD card. I am using this with a Windows 10 laptop with USB tethering. It can also be used standalone with a mouse, keyboard, and monitor, but I have not done this. It makes for a convenient way to learn unix. Here are some tips that might help a first time user with this mode of operation. These tips all address problems that I ran into. The mini USB connector on the Beagle Bone Black C board is used to provide 5 V power and for client connection and is what should be connected to the host computer for power and USB tethering. The full size USB connector is for server side connections, usually to a mouse, keyboard, and monitor. The board should automatically appear as a device in This PC in the file system about ten seconds after connecting the usb cable. There should be an icon titled BeagleBone Getting Started. There will be helpful information in this folder. Then in a remote unix or Linux terminal window, the unix commandssh -Y -l root 192.168.7.2can be used to establish a remote connection. This can be done either with Cygwin, MinGW, or Fedora installed as a virtual machine with the free VMWare Player. All of these are free software. MinGW is the quickest to install and requires the least storage space. However, one will have to manually add two paths to the Windows path environment variable. These two paths areC:\MinGW\bin\C:\MinGW\msys\1.0\bin\To do this, go to Advanced system settings in the System control panel, then click on Environment Variables. Path is listed in the system variables.The MinGW commands can then be used in a Windows Command Prompt window. There is a MinGW Installer desktop program to add or remove packages. By the way, MinGW is usually used to build executables and dll's that are windows compatible using a Linux environment and the GNU gcc, g++, and gfortran compilers and linkers. With both Cygwin and MinGW, the correct packages to install must be chosen. In particular, for Cygwin, openssh and openssl from the Net package list must be installed. A separate unix terminal window can be used to transfer files. As an example:scp -p examplefile.txt root@192.168.7.2:/root/will transfer the file examplefile.txt from the current Windows directory to the root Beaglebone Black directory..To set up an Ethernet internet connection using the Beaglebone Black C board, use the terminal window that has the ssh remote connection and type or docd /etc/network/vi interfacesENTER INSERT MODEauto eth0iface eth0 inet static address 192.168.1.122 netmask 255.255.255.0 gateway 192.168.1.1#netmask and 192.168.1.x obtained using ipconfig on host computer with internet connection#last field in address is arbitrary except must be greater than used by any other device on the networkLEAVE INSERT MODE AND SAVE AND QUITLastly, if one uses more than one Beaglebone Black board on the same host computer, the c:/cygwin/home/don/.ssh/known_hosts file will need to be edited. Remove the line or lines containing 192.168.7.* and append the textHost 192.168.7.* UserKnownHostsFile /dev/null StrictHostKeyChecking no

The SOC in the BeagleBoard comes with 2 PRUs which are like MCUs you can use for similar tasks to what you would use standalone MCUs for. This is in addition to the main CPU, which makes for a very powerful single board computer for embedded projects. There is a great community behind the board to help you get up to speed with good documentation and even books.
