Introduction

Note: The expansion shield is ONLY compatible with FireBeetle 2 ESP32-E IoT Microcontroller (Supports Wi-Fi & Bluetooth).

Not compatible with the FireBeetle 2 Board ESP32-S3 Microcontroller and Firebeetle 2 M0 Development Board.


This expansion shield for FireBeetle 2 is just right for makers who love using terminal blocks for wiring up their projects!

Compared with the previous FireBeetle shields, it comes with additional 7-24V external voltage input and GDI port and adopts terminal blocks to secure wires so as to make connections more stable and reliable. Each terminal block (except GND) has an LED for status indication. Since these LEDs also consume power, which leads to higher power consumption, an LED switch is designed on the board to allow users to turn off the LED when not required.

    A perfect companion board for the FireBeetle 2 ESP32-E! The terminal block expansion makes wiring sensors, relays, and external devices much easier—no more messy jumper cables. The build quality is excellent, and the screw terminals are firm and reliable. It’s ideal for prototyping or deploying stable IoT systems. Works flawlessly with the FireBeetle 2 board and saves a lot of time during assembly. Highly recommended for anyone who needs clean, secure connections in their IoT projects.
