FireBeetle 2 ESP32-C5 IoT development board offers GDI display interface, LiPo battery support

Just the other day, I lamented the lack of options when it came to ESP32-C5 boards featuring dual-band WiFi 6 support. The FireBeetle 2 ESP32-C5 IoT development board made by DFRobot shows that I needed to be more patient… The ESP32-C5 board features 4MB flash, a USB-C port, a LiPo battery connector, and two GPIO headers for expansion, as well as a GDI display connector designed to add an SPI/I2C touchscreen display. The new RISC-V board has about the same features and form factor as the FireBeetle 2 ESP32-S3. It adds 5 GHz WiFi and an 802.15.4 radio for Zigbee, Thread, and Matter, but loses a camera connector, and comes with less memory and storage. FireBeetle 2 ESP32-C5 specifications: Wireless module – ESP32-C5-WROOM-1-N4 SoC – Espressif Systems ESP32-C5 CPU Single-core 32-bit RISC-V processor @ up to 240 MHz Low-power RISC-V core @ 40 MHz acting as the main processor for […]
