Crimspire builds the tooling, compute boards, and modules that the RISC-V ecosystem is missing. From debug probes to certified SoMs — we make RISC-V real for engineers and builders.
Three products. One mission. Filling the tooling, compute, and module gaps holding RISC-V back.
The missing debug tool for RISC-V. Plug-and-play JTAG probe with pre-built OpenOCD profiles for every major RISC-V board. No manual config. No J-Link license. Just works.
A RISC-V compute board built for robotics and industrial use. CAN bus, real-time I/O, and ROS2 support — everything missing from existing RISC-V SBCs.
A production-ready, certified RISC-V SoM for builders who want to ship products — not prototype forever. FCC/CE certified, drop-in compute for your next product.
Every line of HartProbe firmware is open source. Schematics, configs, and OpenOCD profiles — all on GitHub. The RISC-V community deserves open tooling.
MIT licensed STM32 firmware, auditable and forkable.
KiCad schematics and PCB files released openly.
Per-board OpenOCD configs for every supported target.
Full documentation, wiring guides, and examples.
Crimspire LLC is an embedded systems company based in Indianapolis, Indiana. We exist because the RISC-V ecosystem deserves better tooling — and nobody was building it.
We're starting with HartProbe: a debug probe that actually works with your RISC-V board, out of the box, without a forum post and a spare STM32. Then HartBoard, then HartModule — building the connective tissue the RISC-V ecosystem needs to go from hobbyist curiosity to production platform.
We build in public. Open source firmware, open hardware, community first.
HartProbe is in active development. Follow along on GitHub or reach out directly.
