User Interface GPIO
6 GPIO connections are provided (with programmable / alternate functionality). These GPIO can
take 0..3.3V voltage range and +/-6mA of current. Voltage exceeding these limits can result in
damage to the module circuitry.
Interrupt Capability is available on all pins.
PCB Material and layout considerations
The PCB material for the base PCB should be FR4 glass epoxy.
