The RL78/G14 fast prototyping board is a function-rich board to enable rapid product development for IoT endpoint equipment. Users can combine it with the RL78/G1D BLE module expansion board to add Bluetooth low-energy wireless communication functions. The prototyping board is based on the RL78/G14 microcontroller (MCU), which provides a rich set of functions in the low-power RL78 family, making it well-suited for motor control in portable equipment and IoT sensors, as well as industrial equipment.
