Overview
Designed for rapid deployment of edge AI vision models, the Sipeed MaixCAM-Pro combines multi-core compute and integrated hardware peripherals in an ultra-compact form factor. Powered by the Sophgo SG2002 SoC, this developer kit features a 1GHz 64-bit RISC-V C906 core (switchable with an optional ARM Cortex-A53 core) running Linux, a secondary 700MHz RISC-V core running RTOS, and an efficient 8051 low-power core. Upgraded from the base MaixCAM, the Sipeed MaixCAM-Pro adds a 2.4-inch 640x480 IPS capacitive touch display, an onboard 6-axis IMU, an AXP2101 power management IC, and an onboard BM8653 RTC with battery backup, making it an ideal standalone platform for vision AI prototyping and field robotics.
