Ω This is optional and only used for dongle detection. For DB-25 pin 9: On the micro, run to pin 9 to 5V VCC with a 1k resistor. On ESP32, run to pin 35 to 3.3V VCC with a 1k resistor. On each dongle, run a resistor of the given value between DB-25 pin 9 and GND.
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.
All connected pins can also function as Digital pins.
