Beetle ESP32-C3
Overview
The DFR0868 is a compact, RISC-V based development board powered by the ESP32-C3 single-core 32-bit processor running at 160MHz. It features integrated 2.4GHz Wi-Fi and Bluetooth 5 (LE) connectivity in a small 25mm x 20.5mm form factor designed for space-constrained IoT projects. The board includes 400KB of RAM, 4MB of flash, and onboard lithium battery charging management for portable applications.
Why Choose This Part
This board provides a powerful RISC-V architecture with 12-bit ADC resolution and 6 PWM channels in a miniature package. The built-in charging circuit simplifies the design of cordless devices, while the IO 5V tolerance on specific pins provides flexibility when interfacing with legacy hardware.
Applications
Key Specifications
Getting Started
The board can be programmed using the ESP-IDF or the Arduino IDE by selecting the ESP32-C3 Dev Module. Connect via the onboard USB port for flashing and serial debugging. Ensure the 3.3V power requirements are met if not using the VIN 5V input or a lithium battery.
