Say hello to our latest creation – the doppler!
A Cortex M4F Microcontroller + FPGA development board. It comes in the same tiny form factor similar to a Teensy and is open source.
We are very excited about FPGA’s but getting started with them is daunting especially because of the ecosystem of proprietary toolchains and expensive hardware. The doppler takes away most of these pains by providing all the tooling to get you up and running.
There are two chips on the board a SAMD51 ARM Microcontroller and an ICE40 FPGA. The Microcontroller is easily programmable with, for example, the beginner-friendly Arduino environment. It also needs to be used to upload the configuration as a bitstream to the FPGA. This guide goes in detail on how to set up both development environments for the SAMD51 and the ICE40.
For now all documentation is in the github repository: https://github.com/dadamachines/doppler/
