GPIO I2C pHAT is an I2C switch for Raspberry Pi which remaps the I2C bus (pins 3 & 5) to 1 of 4 additional buses, allowing any I2C based HAT / add-on board to use an alternative I2C bus, without the need for multiplexers or expanders.
Makes use of the extra hardware I2C buses introduced on Raspberry Pi 4 (BCM2711) or software I2C (bit bang) for older models. Switching is controlled using a 4-position double-pole slide switch, which allows you to quickly switch between buses.
Multiple GPIO I2C boards can be stacked along with other HATs or pHATs, and it's fully compatible with our HAT RACK mounting boards.
Includes a breakout header for the 4 extra I2C buses. These are always connected to the associated GPIO pins so can be used regardless of the switch position. Note: external pull-up resistors to 3.3V required.
Add required dtoverlay parameter(s) to
/boot/config.txt and reboot.
|Switch Position||Hardware I2C (Pi 4)||Software I2C (Bit Bang)||GPIO|
Note: When using multiple software I2C buses, add the parameters from highest to lowest, i.e., 6, 5, 4, 3.
