Ω This is optional and only used for dongle detection. On the microcontroller side, put a 1k resistor between DB-25 pin 9 and VCC (3.3v for ESP32, 5V for Micro). On each controller dongle, put a resistor of the given value between DB-25 pin 9 and GND. Ω This is optional and only used for dongle detection.
