Colorlight 5A-75B: A dive into a popular low-cost ECP5 (FPGA) development board
Summary
The Colorlight 5A-75B is a low-cost receiver board using the Lattice ECP5 FPGA that can be programmed with the open source Yosys toolchain. The article covers hardware specs, the open hardware approach, and how to hack the board via JTAG, including a caveat about replacing the 74HC245 drivers. It positions the board as an accessible entry point for learning open source FPGA workflows and hints at a forthcoming post detailing a Verilog project to blink the onboard LED.
