1 CM1126B-P Introduction
1.1 Summary
The CM1126B-P system-on-module is equipped with Rockchip's RV1126B-P build in quad-core Cortex-A53, 3.0 TOPs NPU and RISC-V MCU. It is designed specifically for the IPC/CVR devices, AI Camera devices, intelligent interactive devices, and mini robots. The high performance and low power solution can help customers to introduce new technologies more quickly and enhance the overall solution efficiency. The least size can put on 38board. Following the hardware revision from CM1126 (V1) to CM1126B-P (V2), where the SoC is updated to the RV1126B-P, the Reset & OTG_VBUS signals and WIFI/BT module's GPIO voltage must operate at a 3.3V logic level.
