Description
ESP8266 Uno R3
ESP8266 based development board compatible with Arduino UNO R3 interface.
Form factor compatible with Arduino? UNO R3
Compatible with most ESP8266 modules.
Type-C interface with automatic loading scheme
DC power supply accepts 7 ~ 16V input voltage
ESP8266 I/O starvation problem is minimized with an optimized I/O multiplexing scheme.
The ADC interface uses an op-amp follower circuit to expand the input voltage range of the ESP8266 ADC from 0~1V to 0~5V.
Independent power, link indicator and user LED indicator (connected to GPIO2)
