What is it?

The OKD Bee is a thumb-sized tiny ESP32-C3FH4 SoC development board with 11 GPIO, I2C and SPI supported. It has WiFi and Bluetooth 5 with an SMT antenna connector. Powered and data by USB Type C.

This board equips the highly-integrated ESP32-C3FH4 SoC. The chip has been installed with a complete 2.4GHz Wi-Fi subsystem which means it supports Station mode, SoftAP mode, SoftAP & Station mode, and promiscuous mode for multiple Wi-Fi applications. It works under an ultra-low power state, and also supports features of Bluetooth 5 and Bluetooth meshing. There is 400 KB SRAM & 4MB NOR Flash on the chip, allowing for more programming space, and bringing more possibilities to the IoT and Arduino control scenarios. This has castellated header pins holes for easy integration with other PCBs and projects!

Being new to the OKD family, this board maintains an extremely tiny form-factor design and elegant productization of single-sided components mounting and gold ENIG coating. This board does not come included with an external antenna, but supports any small SMT antenna. There are 11 digital I/O that can be used as PWM pins and 4 analog I/O that can be used as ADC pins. This board supports UART, IIC, and SPI serial communication ports, also including IIS (Internet Information Services) and encryption. Utilizing its small and elegant hardware designed in the USA and the powerful onboard chip, programming by Arduino, PlatformIO, MicroPython, or ESP-IDF, it offers more functionality and flexibility for wearables, sensors, smart displays, and portable devices or other applications.
