RA6M3 Evaluation Board
ARM Cortex-M4 @ 120 MHz

M13design RA6M3-EK is a complete evaluation and development platform for the Renesas Electronics® based RA6M3 Cortex®-M4 R7FA6M3AH3CFC microcontroller. The many hardware features on the board helps users to quickly evaluate all the available peripherals (10/100-Mbit Ethernet, microSDTM card, USB host/device, Audio codec with 4-pole Jack, SDRAM, Quad-SPI Flash memory, 4.3-inch colour LCD-TFT with capacitive touch panel, and many others) and to develop their custom applications. PMOD™ and mikroBUS™ connectors make it possible to easily extent the boards features (Sensors, communication and network modules and many more). The integrated JLink-OB debug probe provides in-circuit debug and programming for the RA6M3 device and also a built-in VCOM functionality.
