The Orange Pi CM4 is an open-source SBC (Single Board Computer) which is Orange Pi’s answer to the Raspberry Pi Compute Module 4. Following the same form factor and modular design, the Orange Pi CM4 features a high performance CPU, GPU, LPDDR4 SDRAM, on-board eMMC, video output support, camera interface support, gigabit Ethernet support, WiFi 5, BT5.0, and the list goes on. The Orange Pi CM4 is a more compact version of the Orange Pi 3B, measuring only 55x40mm. At the heart of the device sits a Rockchip RK3566 64-bit 1.8GHz quad core Cortex A55 processor, alongside a Mali G52 2EE graphics processor, with 4GB of LPDDR4 SDRAM and 32GB on-board eMMC to top it all off. Compatible operating systems include Orange Pi OS, Android 11, Debian 12, Ubuntu 22.04 and OpenHarmony to mention a few.
Please Note:
The Orange Pi CM4 cannot be used standalone and requires a base board to function correctly. You can find a link to the Orange Pi Base Board at the bottom of this page.
