M5Stack ATOMIC PortABC Extension Base
Description
The M5Stack ATOMIC PortABC Extension Base is a Grove port expansion base designed for ATOM series hosts. It makes it easier to connect I2C, UART, and GPIO Unit expansion modules through the familiar Port A, Port B, and Port C interface layout.
The base is built for compact multi-function node controllers and supports several mounting methods, including hanging, LEGO-style connection, and screw fixation. It is useful when an ATOM project needs multiple Grove-style expansion interfaces in a small and simple base.
Features
- Port A/B/C expansion: supports I2C, GPIO, and UART Unit module connections.
- ATOM series support: compatible with ATOM series host controllers.
- Flexible mounting: supports hanging, LEGO-style connection, and screw fixation.
- Compact node design: suitable for building multi-function mini-node controllers.
- Pinout reference included: package includes a pinout diagram for quick wiring reference.
