R4 Minima Development board Suitable For Arduino. The R4 Minima runs on the Renesas RA4M1 (Arm Cortex-M4) processor, with a clock speed of 48MHz. In addition to that, the SRAM has been upgraded from 2kB to 32kB and the flash memory has been increased from 32kB to 256kB to accommodate to more complex projects. Furthermore, in response to requests from the for Arduino community, the USB port has been upgraded to USB-C and the maximum power supply voltage has been increased to 24V. The board provides a CAN bus, allowing users to minimize wiring and perform different tasks by connecting multiple extension boards. Finally, the new board also includes a 12-bit analog DAC.<br><br>Note: Different batches may have different appearance, which does not affect use.
