As I wanted to enable solder-free prototyping I quickly designed this breakout board for the ESP8266-03 modules.
Specifications:
- USB input
- 3.3V 1A LDO
- included breadboard
- 1k resistors on all IOs
- ESP8266-03 soldered onboard
- FT230X USB to UART converter
- 3 LEDs connected to the FT230X
- available IOs: GPIO0/2/12/13/14/15/18
- button to start the ESP8266 bootloader
- 0ohm resistor to be unsoldered to allow 3.3V current measurement
- 0ohm resistor to be soldered to allow FT230X to start bootloader jumping procedure

The board obviously is open source so please feel free to modify it as you wish.
