Features: Suitable for R4 Development board WIFI / Minima Official Original Option. The new Arduino R4 comes in two versions: the R4 WiFi and the R4 Minima. It runs on the Renesas RA4M1 (Arm CortexM4) processor, with a clock speed of 48MHz, which provides a 3x increase over the R3. 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 Arduino community, the USB port has been upgraded to USB C and the maximumpower 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.
