The Adafruit GPIO Expander Bonnet expands your Raspberry Pi by a further 16 digital inputs and outputs. The 16 I / Os can be reached via two 16-pin connections. Each I / O has its own GND pin and can be configured either as an output or as an input with an internal pull-up resistor. Each output delivers up to 20 mA - enough to connect simple LEDs directly. The total current consumption across all outputs should remain below 125 mA. The Bonnet works with 5 V as standard, but can also be set to 3.3 V via a solder bridge. An existing level converter ensures that communication with the Raspberry Pi always takes place at 3.3 V. The Adafruit GPIO Expander Bonnet is delivered assembled and tested and can be plugged directly onto your Raspberry Pi. You can solder the two enclosed IDC sockets if ne.
