ColorLite: remote power control on a $15 FPGA board

Tue, 02 Jun 2026 12:00:00 +0200

A $15 ColorLight ECP5 board, a LiteX SoC with Ethernet, and a cheap relay module: remote power-on/off for an office PC during COVID, built with the fully open-source Yosys/NextPnr toolchain. With a note on reversing boards from the FPGA side.

mquickjs on LiteX: JavaScript on an FPGA softcore

JavaScript running bare-metal on a RISC-V softcore inside a LiteX SoC, with framebuffer demos and a live browser editor served straight from the FPGA. No host, no transpilation.

FPGA development with LiteX in the AI era

Tue, 02 Jun 2026 09:00:00 +0200

LiteX was always command-line and text first, for cost reasons. It turns out that’s exactly what an AI agent needs to drive an FPGA. Here’s the methodology we use now, with LiteNVMe and M2SDR as real examples.

QEMU co-simulation in LiteX
