Beijing-based Bitmain, which is known primarily as a leading vendor of bitcoin mining chips and computers, also has a “Sophon” AI chip business built around its BM1680 and more recent BM1682 Tensor Computing Processor (TPU) AI chips. Bitmain recently announced a third-gen BM1880 TPU along with a Sophon BM1880 Edge Development Board (EDB) 96Boards CE SBC, referred to by 96Boards.org as the “Sophon Edge.” This is the first board we’ve seen with a RISC-V companion MCU. The unidentified chip is probably an MCU-like RISC-V part for real-time processing, possibly designed by Bitmain. That’s a high clock rate for an MCU, so it’s possible it’s an alternative Linux chip in addition to the dual -A53 block. There’s a boot switch listed in the hardware manual that lets you switch between Arm and RISC-V for booting.
