Overview

The GR-KURUMI board incorporates the 16-bit, low-power consumption, RL78/G13 Group MCU (R5F100GJAFB). Compatible with Arduino Pro Mini, this board can use existing sample codes, ensuring easy use with the Arduino language and standard libraries from both hardware and software aspects.

Key Features

The following special features, unavailable in Arduino Pro Mini, are perfect for designing small and low-power gadgets.

  • Runs on a single-battery. Incorporates a voltage booster from 0.9V to 3.3V (or 5V)
  • Includes a real-time clock with alarm function, facilitating a high-precision real-time counter (RTC)
  • Low-power mode: Arduino-like library allows for easy setup of the RL78 standby mode (STOP/SNOOZE)
  • GR-KURUMI's LED hair accessories: Unique GR-KURUMI features are illustrated in LEDs with glowing full-color hair accessories
