C3FH4 RGB features an ultra-compact design with one risc-v 32-bit single core processor at 160MHz on a PCB, built-in 400 KB SRAM and 4 MB Flash , integrated with 2.4 GHz Wi Fi and supporting long-distance Bluetooth 5 (LE), with industry-leading RF performance and low power consumption.By combining RSA-3072-based secure boot and the AES-128-XTS-based flash encryption, offers a more secure way to answer the Bluetooth security concerns.

With low power consumption: It is ideal for any space-constrained or battery-powered devices such as wearables, medical devices, sensors, and other IoT devices.and fully compatible with Arduin, MicroPython, ESP32-IDF, and other mainstream development platforms to quickly build various applications.

HIGH INTEGRATION: C3FH4 RGB Including 2 channels of 5V - > 3.3V DC / DC, GPIOx11, programmable RGB light x25, button x2, finely tuned RF circuit, providing stable and reliable wireless communication.
