ATOM Series Grove Port Expansion Base for I2C, GPIO, and UART Unit Connections
The M5Stack A130 Atomic Port ABC Base is a Grove port expansion base designed for M5Stack ATOM series controllers. It provides convenient access to PORT A, PORT B, and PORT C interfaces, allowing compatible I2C, GPIO, and UART Unit expansion modules to be connected to an ATOM host. This makes it useful for compact embedded systems that require multiple sensor, control, or communication interfaces.
The extension base also supports several mechanical mounting methods for flexible installation in prototypes and finished devices. It can be mounted using hanging, LEGO-compatible, or screw-fixation methods, making it suitable for multifunctional mini-node controllers, IoT devices, automation projects, and compact control systems built around the M5Stack ATOM ecosystem.
Key Features
- PORT A Support: Provides connectivity for compatible I2C-based M5Stack Units.
- PORT B Support: Supports compatible GPIO-type Unit expansion modules.
- PORT C Support: Provides connectivity for compatible UART-based Units and peripherals.
- ATOM Compatibility: Designed specifically for use with M5Stack ATOM series hosts.
- Grove Expansion: Simplifies connection of compatible Grove-interface sensors, actuators, and communication modules.
- Multiple Interfaces: Supports I2C, GPIO, and UART expansion through a single compact base.
- Flexible Mounting: Supports hanging, LEGO-compatible, and screw-fixation installation methods.
- Compact Expansion: Suitable for building small multifunctional controllers without extensive custom wiring.
- Modular Development: Allows compatible M5Stack Units to be added or changed according to project requirements.
