IZIRUNF4 based on ARM Cortex M4 for middle applications like motor control, display, CAN control, Ethernet and more.

IZIRUNF4 module it’s a small and compact board that allows you to speed up your development thanks to build-in peripherals like EEPROM flash, SRAM, NOR flash, leds, buttons, quarts and debug connector. The module has M.2 connector footprint, with up to 67 pins which can be used to communicate with the external peripherals via I2C, SPI, CAN, UART protocols.
