Beetle ESP32 - C3 RISC-V Core Development Board for IoT - 

DFR0868 is a Beetle ESP32 - C3 (RISC-V core development board). Beetle ESP32-C3, mainly intended for IoT applications, is a controller based on ESP32-C3 RISC-V 32bit single-core processor. On a coin-size board of 25 x 20.5mm, the Beetle ESP32-C3 is up to 13 IO ports broken out, so you don't have to worry about running out of IO ports when making projects. Moreover, its mini size effortlessly integrates into a miniature devices and offering both powerful functions and connectivity. For instance smart wearables, the Beetle ESP32-C3 microcontroller's mini size make it an ideal choice for intelligent wearables like smartwatches and smart glasses. It can connect with smartphones, enabling health monitoring, and delivering message notifications, it accomplishes all this without sacrificing the device's form factor or increasing its weight. Typical applications include indoor positioning, smart farms, smart home and IoT.
