Open Source Hardware: SH-C30A comes from the CANable open hardware project, and we publish our design back. Full schematic and PCB layout are on GitHub (dsdtech-official) as editable files under CERN-OHL-S-2.0, with firmware images. Inspect, modify, build your own. USB to CAN Bus: Connect your computer directly to the CAN bus. Built-in 120 ohm termination switch and programming switch (a DSD TECH first on a USB CAN adapter). Flexibility on Open Protocols: Ships with candleLight firmware speaking gs_usb — its driver is built into the Linux kernel, so it works as a standard SocketCAN interface with nothing to install. Compatible with cangaroo, can-utils, python-can and BUSMASTER. Reflash to slcan firmware at canable.io. New Firmware, Free on GitHub: The stock build ignores the 24 MHz crystal. Our build uses it and lights the TX/RX LEDs the stock build left dark. Units from September 2026 ship with it preinstalled; earlier units can be updated over USB — free and optional.
We'd like to share an important update: Our SH-C30A has officially been open-sourced on GitHub.
