The ExtPort for Core2 from M5Stack is an expansion module for the M5Stack Core2 converting to the Grove interface. It provides PortB/C/D/E 4 Grove interfaces, and PortD/E can be configured with different GPIOs via internal dip switches.

Check out the designer's signature on the top of the PCB - neat!

Note

• Before use, please switch one of the 3-pin dip switch to be ON. Remember that, only one of the dip switches can be set to ON, or it may damage the module
• If you need to use the Core2 bottom board, you will need to cut off the four support feet of the PROTO module (as shown below), to avoid interference with the bottom board, and use M3 screws to fix
