M5Stack Mini Proto Unit 40 Holes
Shopping information
Description
Unit Mini Proto is a compact 40-hole universal prototyping board in the M5Stack Unit form factor. The Unit Mini Proto lets you freely design small circuits on the board and connect them to M5Core through the HY2.0-4P Grove port.
When a project needs a simple custom circuit with a protective case, the Unit Mini Proto provides a quick prototyping base. Different HY2.0-4P ports can expose different ESP32 pins, so the Unit Mini Proto can be wired for PORT.A, PORT.B, or PORT.C circuit connections.
Features
- Unit Mini Proto compact universal board with 40 prototyping holes.
- HY2.0-4P Grove interface for connection to M5Core.
- Supports PORT.A, PORT.B, and PORT.C ESP32 pin connection options.
- Two LEGO-compatible holes for mechanical mounting.
- Small 32.0 x 24.0 x 8.0mm form factor for embedded circuit experiments.
- Suitable for simple add-on circuits that need a protected Unit-style enclosure.
