Terminal Block Board for FireBeetle 2 ESP32-E IoT Microcontroller

The Terminal Block Board for FireBeetle 2 ESP32-E is an expansion shield built for makers requiring secure, vibration-resistant wiring in their IoT builds. It breaks out every microcontroller pin into screw terminal blocks while introducing wide-voltage power input and display connectivity.

Secure screw terminal breakout

The shield extends all FireBeetle 2 ESP32-E pins to screw terminal blocks for stable and dependable wiring. It breaks out 12 digital ports, 5 analog ports, 3 I2C interfaces, and 1 SPI interface, alongside multiple 5V, 3.3V, and GND connections.

Wide voltage power input

An onboard power terminal block accepts an external 7V to 24V DC power supply to run complex setups. A dedicated red VIN LED gives immediate visual feedback when external power is connected.

Switchable pin status indicators

Each terminal block features an integrated status LED, using red for power and blue for GPIO logic levels. A physical onboard switch lets you toggle all 34 indicator LEDs off to save energy in low-power deployments.

Dedicated GDI display interface

An onboard General Display Interface (GDI) port enables direct ribbon cable connection to compatible screens. This streamlines adding visual interfaces without consuming terminal block wiring space.

Microcontroller compatibility

This expansion board is designed specifically for the FireBeetle 2 ESP32-E IoT Microcontroller. It is not compatible with FireBeetle 2 ESP32-S3 or FireBeetle 2 M0 development boards.
