The Orange Pi CM4 base board is an official Orange Pi base board that can be used with the Orange Pi Compute Module 4, with 40Pin GPIO interface and standard CM4 connector. It can be used as a development system for Compute Module 4 and as an embedded board integrated into the end product, supporting access to Orange Pi CM4/Raspberry Pi CM4 core board.
Orange Pi Compute Module 4
Small size, high speed
Quad-core 64-bit Cortex-A55 processor, 2GB/4GB/8GB (LPDDR4/4X), 4K HD display, Wi-Fi5+BT 5.0, BLE support, different specifications of eMMC flash memory and wireless module, can be widely used in industrial IoT field.
Compute Module 4
Multiple interfaces, more convenient to use
Equipped with CSI/DSI/FAN/HDMI/USB/RJ45 Gigabit LAN port/TF card/M.2 M-Key and other interfaces.
