Comma.ai's $249 eGPU Dock Runs Open-Source Firmware
Chestnut – eGPU dock with open-source firmware
Comma.ai, known for its open-source driving assistant openpilot, has released Chestnut, a USB4 eGPU dock with open-source firmware. Priced at $249 for the dock alone or $799 with an RX 9060, it's designed to boost compute for driving models but also appeals to PC builders who want to audit and reflash the bridge chip firmware. The dock uses an ASM2464PD controller, and the firmware is available on GitHub.
That is the part worth paying attention to: eGPU enclosures have always been closed boxes, but Chestnut breaks that open.
