ESP8266 Board Tester (I/O + WiFi)
- Arduino core for ESP8266
- Features:
* Serial menu for quick tests
* Simple web UI to view digital inputs & ADC, toggle outputs
* WiFi scan, connect (via Serial), start SoftAP
Pin notes:
- Be careful with GPIO0, GPIO2, GPIO15: they affect boot. Use them carefully.
- A0 is ADC (analogRead)
