Shrike

Shrike is a family of low cost affordable FPGA development board along with a host microcontroller. Currently the family features these two members -:

1. Shrike-lite (FPGA with RP2040)
2. Shrike (FPGA with RP2350)
3. Shrike-fi (FPGA with ESP32-S3)

And a lot version under development.

We usually work on very complex FPGA-based projects built around Vaaman and its upcoming series. However, Shrike is a passion project at Vicharak, driven by our love for engineering across both embedded microcontrollers and FPGAs.

Our goal is to make FPGAs accessible to everyone by offering robust toolchains, high-quality hardware, and strong ecosystem support. We’re committed to keeping the hardware prices extremely low, and every piece of software for Shrike will be completely open-source.

We at vicharak have kept in mind need of a learner, maker and a hobbyist while designing this art. This dev board will be your stepping stone in the field of FPGA, reconfigurable and heterogenous computing.

We invite contributors from all over the world to join us in this mission. Together, let’s make FPGA technology truly accessible to all.
