The M5StampS3 Grove Breakout Board is a dedicated Grove expansion module for the M5StampS3 , designed to simplify sensor and module connections. It features six Grove interfaces (I2C, GPIO, UART) and is compatible with M5 PortA/B/C standards, making it ideal for rapid prototyping in IoT and embedded systems.
It includes a battery holder for 16340/18350 lithium cells and a 1.25mm@2P lithium battery connector, allowing independent power delivery to the system. The board also supports power source switching between USB and battery, and has an onboard touch reset switch connected to the EN pin.
Integrated with a lithium battery charging chip, a 5V boost system, and a battery monitoring circuit, this board offers a stable and efficient power solution. Pre-drilled mounting holes ensure easy installation. It’s an excellent choice for IoT applications, wearable devices, robotics, automation, and educational projects.
Note: To fully utilize all Grove interfaces, the M5StampS3 must be connected using 1.27mm pin spacing.
