Description
StampS3 GroveBreakOut is an expansion board designed specifically for the M5StampS3, equipped with 6 Grove interfaces, compatible with M5's portA/B/C standards (including I2C, IO (input/output), and UART interfaces). This expansion board features a built-in 16340/18350 lithium battery holder and a 1.25mm@2P lithium battery interface, allowing it to independently power the entire system. It also includes a battery power switch and a switch for toggling between USB and battery power. The onboard tactile switch is connected to the EN pin for reset control. Additionally, the board includes a lithium battery charging chip, a 5V boost system, and a battery level detection circuit, providing a stable and reliable power solution. Pre-drilled mounting holes are available for easy installation. This product is suitable for education and prototyping, IoT projects, wearable devices, automation, and robotics.
