Description:
Feature
This is an I/O expansion board module which is used to increase the GPIO number of a microcontroller. This module can support up to 16 numbers of GPIO using 2 wires.
Note 1: Bank A (0 to 7) and bank B (8 to 15) are supplied by VCC1 and VCC2, respectively. Both Supplied voltage is according to the input voltage. To supply the voltage externally (1.2 to 3.6 VDC), please cut the 2 pad jumpers at the back of the board.
Note 2: All the pins support PWM and normal digital IO.
