In case you need a cheap and compact ESP8266 board with integrated USB to TTL debug interface, a photo resistor, and/or some buttons, a white brand board based on ESP-12F could be interesting.
- ESP-12F module with Espressif ESP8266EX SoC
- Connectivity – WiFi 802.11 b/g/n
- 2x 8-pin headers with GPIOs, VCC, GND, Reset, ADC, and UART
- USB – 2x micro USB port (one for power, one for debugging ?)
- Misc – Photo resistor, RGB LED, three buttons for power, reset and firmware upgrade (I think)
- Dimensions – Small
Witty cloud might not be the same of the board itself, but could be a cloud service launched in China, as some of the screenshot on Aliexpress could imply. All I could find are some websites vaguely mentioning GoKit 3.0 and Witty Cloud 3.0, but it does not make much sense. If Chinese readers could provide some insights here it would be nice.
The board sells for as low as $3 + shipping on Aliexpress, which amounts to $4.85 in total in my case.
