This test board uses the SAME70 microcontroller by Atmel that runs at 300Mhz frequency.
It was designed to provide the most usable peripherals : UART, PWM, AD, DAC, I2C, SPI
The purpose is not to replace the evaluation board which is most complete and easily debugable, but was designed for my tests regarding some projects that am running in //.
I don't know if it worth sharing, but don't hesitate to comment or contact me for any question!
