Doppler 1.0


The doppler is an ARM Cortex SAMD51 M4F Microcontroller + iCE40 FPGA development board. It comes in the same tiny form factor similar to a Teensy and is open source.



Please note these boards are still beta. dadamachines has been testing and using them internally for more than 3 months. But there might still be some details which could / should be changed for a larger batch.



Cheers to Sven Braun and Johannes Elias Lohbihler for designing this, Adafruit for unlocking the SAMD51 core for Arduino and last but not least Clifford Wolf and the whole community for running Project IceStorm, which is reverse engineering the Bitstream of Lattice iCE40 FPGAs.
