ESP8266 is a highly integrated chip designed for the needs of a new connected world. It offers a complete and self-contained Wi-Fi networking solution, allowing it to either host the application or to offload all Wi-Fi networking functions from another application processor. Specifications: Serial/UART baud rate: 115200 bps Input power: 3.3V I/O voltage tolerance: 3.6V Max Flash Memory Size: 1MB (8Mbit) WiFi security modes: WPA, WPA2 Package Including 5 * ESP8266 Wifi Transceiver Module

Awesome little microcontroller
Awesome little microcontroller, so long as you know what you're doing with it.The chip has 2 GPIO pins, but GPIO0 *must* be pulled high for normal operation. That means that in order to use GPIO0 in your application, you will have to mess around with pull up resistors or some type of buffer and logic inversion in order to use the pin.If you don't need the absolute smallest wifi enabled microcontroller around, I'd suggest going with an ESP32 based board, like the Wemos D1 Mini Pro. It's still pretty small, the same command set, but WAY more free GPIO pins that you don't have to fiddle with in order to use.Also, this one is not breadboard friendly. You will either need a caddy/adapter for the board, or you will need to use jumper wires. You'll also need a USB to Serial adapter like the ones made by FTDI.

SPI Flash
No signs of SPI flash failure yet (running Micropython) impressive at this bulk and price point. Flash is Winbond unlike most which have no branding on them.

Good but one arrived damaged
Unfortunately 1 arrived damaged. Tested the other 4 and they work as they should so overall if it wasn't for the damaged one it would have been a good buy. Took off 2 stars for the board
