I ordered one of these boards a couple of weeks ago and it finally arrived today.
The baseboard has a CH340G UART adapter with a micro USB port, 2 buttons (reset/flash) and a nodemcu-style reset circuit for automatic programming. Pin spacing is the same as the white ESP-12 breakout boards, but there's no LDO on the baseboard. So you should only use it if you have a LDO on the breakout board!
The ESP board also has a micro USB port (power only) and an AMS1117-3.3 LDO. There are a few periphials onboard:
- a button connected to GPIO4
- a RGB LED (common cathode) connected to GPIO12/13/15
- a LDR connected to the ADC. The LDR has a resistance of about 1k5 Ohm in darkness and is connect on the ground side of the voltage divider. The corresponding pull-up is 470 Ohm.
The ESP comes pre-flashed with a demo, that fades different color on the RGB LED.
Here are some crappy pics of the boards:
