Additional UART Pins on ESP32 Chip #2
Description
Excellent board with RTK and a microprocessor in the same PCB. Wondering for field-deployment Wi-Fi and Bluetooth are limited but other Radios 900mHz or XBEE can be used, Does the ESP32 has spare pins or UART to accomodate an external RS-232 device? if so, can you point me which pins/UART?
