UART pins for programming and serial I/O are GPIO1 (TXD, pin 3) and GPIO3 (RXD, pin 4).

## Olimex MOD-WIFI-ESP8266
This is a stripped down version of the above. Behaves identically in terms of jumpers but has less pins readily available for I/O. Still 2 MB of SPI flash.
## Olimex ESP8266-EVB
It's a Olimex MOD-WIFI-ESP8266-DEV module installed on the headers of a development board which features some breakout connectors, a button (GPIO0) and a relay (GPIO5).
Programming is pretty straightforward: the board is supported in the Arduino IDE after adding the [board manager URL](http://arduino.esp8266.com/versions/2.0.0/package_esp8266com_index.json). To download a program you just have to connect GND/RX/TX from a serial/USB adapter to the UEXT connector and press the only button before applying power to enter UART mode.
Don't connect 5V from the serial/USB adapter to the board or you won't be able to power cycle it for UART mode.
You can find the board schematics [here](https://github.com/OLIMEX/ESP8266/blob/master/HARDWARE/ESP8266-EVB/ESP8266-EVB_Rev_A.pdf).
[This guide](https://www.olimex.com/Products/IoT/ESP8266-EVB/resources/ESP8266-EVB-how-to-use-Arduino.pdf) is also useful for the first setup, since it contains the UEXT connector pinout.
Board variants include:
* ESP8266-EVB-BAT: comes with built-in LiPo charger and step-up converter
* ESP8266-EVB-BAT-BOX: as above, but enclosd in a plastic box (non-weatherproof)
