Info
All power supply pins (VCC, VCC_CORE) must be connected.
All ground pins (GND, GNDA, . . . ) must be connected.
Analog inputs (AI) are 5V single ended or differential inputs (Input range: GNDA
to V5). Use voltage dividers or operational amplifiers to scale down higher input
voltages.
Digital inputs (I) resp. (IO) are 3.3V single ended inputs.
IO Description
AI analog input, 3.3V
I digital input, 3.3V
IO digital input or digital output, direction programmable, 3.3V
O digital output, 3.3V
