Module ExtPort For Core2
SKU:M123
Description
Module ExtPort For Core2 is a Grove interface expansion module designed specifically for the M5Stack Core2. The module routes the Core2's M5-Bus IO externally and provides 4 Grove expansion interfaces (PORT.B/C/D/E). Among them, PORT.D/E can flexibly configure GPIO connections via onboard DIP switches, effectively enhancing the peripheral expansion flexibility of the Core2.
Features
- 4 x Grove Interfaces (PortB/C/D/E)
- 4 x 3-Position DIP Switch (PortD/E)
- 1 x 5Pin@2.54mm Male Header
Includes
- 1 x Module ExtPort For Core2
Applications
- Multi-sensor, Multi-actuator Expansion
- DIY Projects
