This expansion shield for the FireBeetle 2 ESP32-E microcontroller is just right for makers who love using terminal blocks for wiring up their projects! Compared with the previous shield version, this terminal block board comes with an additional 7-24V external voltage input, 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. Note: The expansion shield is ONLY compatible with the FireBeetle 2 ESP32-E IoT Microcontroller.
