Module ExtPort For Core2
Description
Module ExtPort For Core2 is a stacking expansion module specifically designed for the M5Stack Core2 to interface with Grove connectors. It provides PORT.B/PORT.C/PORT.D/PORT.E 4 Grove interfaces, where PORT.D/PORT.E can be configured with different GPIOs via internal DIP switches.
Note
Note:
1. The front of ExtPort For Core2 features a collaborator's signature.
2. Before use, ensure that the corresponding DIP switches are set to
3. If you need to use the Core2's bottom cover, you must cut off the four support legs of the PROTO module (as shown below) to avoid interference with the cover and prepare M3 screws of appropriate length for fixation.

2. Before use, ensure that the corresponding DIP switches are set to
ON. The "1" position of all DIP switches is set to ON by default. Remember that only one position in each DIP switch should be set to ON; if multiple positions are set to ON, the device may be damaged.3.
