BPI IO Extend Board
This module is designed specifically for Banana Pi IO expansion modules, which can effectively solve the Banana Pi's IO port insufficiency. The module uses four 74HC595 chips to expand 32 IO ports.
The top of the module will expand the IOs of Banana Pi and can be cascaded with more IO expansion modules for a theoretically unlimited expansion.
- Expands 32 GPIO
- Infinity connection for the same modules
- Wiring Pi API, sample code
