RM182X M.2 2280 AI Compute Co-Processor Module (20TOPS)
RM182XMC0 (including RM1820MC0 and RM1828MC0) is a high-performance AI compute co-processor module supporting 3B / 7B large models (RM1820MC0 supports 3B, RM1828MC0 supports 7B), designed for AI inference and machine vision applications.
The module uses an M.2 Key M gold-finger connector and measures 22mm × 80mm. Customers only need to design a simple carrier board to integrate it into edge or embedded devices.
The core value
Large-model inference delivered as a standard M.2 2280 card. As long as your host has a free PCIe M.2 slot, dropping in one card adds 20 TOPS of local compute — no host replacement, no cloud round-trip.
