Gowoops 2 PCS of ESP8266 ESP-12F WiFi Serial Module Board for Arduino, Wireless Transceiver Remote Port Network Development Board

Product came exactly as described! ...Unfortunate that other buyers of this product don't read or understand the product fully before purchasing and then leave negative reviews simply because they don't understand what they're buying. If you are new to electronics, this product is SMD or Surface Mounted Device and requires a Footprint or Breakout board to be soldered to.

These two devices came loose in a static free bag and found when programming that memory had been written to before. These are not going out in the field.

The devices worked great and do have 4Mbytes of Flash so OTA updates are not a problem. I had no issues hand soldering the devices to my project PB.

The holes for the pins are too small for the standard pin headers you will find (0.1mm). I think these holes are 0.68mm, which I have only found pogo pins for (not pin headers). See the picture for a comparison.

Of the two pieces that arrived, I have used only one so far. I have it on a Raspberry Pi Zero 1.2 for Wi-Fi. It works as planned.
