MPINO-8A8R(T)-S 7-Segment LED Wiring

Connect up to 4 displays using the ENC/FND and PWM ports.

MPINO-8A8T-S: The standard board cannot drive a 7-segment display on the ENC/FND connector because of the 4.7 kΩ pull-downs on D24 and D25. With the 7-segment control option, we change them to 10 kΩ pull-ups. The PWM terminals (devices 1~3) are not affected, so the standard board can connect up to 3 displays.
