It uses the same BCM2837B0 quad-core ARM Cortex-A53 processor found in the Raspberry Pi 3 Model B+, running at 1.2GHz with 1GB LPDDR2 RAM — but packaged in a compact DDR2 SODIMM form factor with 200 pins. Four storage variants are available: CM3+/Lite (no eMMC, boots from carrier board storage), CM3+/8GB, CM3+/16GB, and CM3+/32GB with onboard eMMC flash. The module exposes over 45 GPIO lines, 2 CSI camera interfaces, 2 DSI display interfaces, 2 HDMI outputs (via carrier board), I2C, SPI, UART, USB 2.0, and Ethernet PHY signals — all accessible through the custom carrier board. No WiFi or Bluetooth is integrated on the module itself. The CM3+ is compatible with the official Raspberry Pi Compute Module IO Board v3 (CMIO), which provides a reference carrier board for development. The open-source IO Board design files are available for engineers building production carrier boards. The module is suited for digital signage, industrial gateways, camera systems, thin clients, and other applications needing Linux compute capability in a compact, socketed form factor. ## Where to Buy - [Adafruit (CM3+ 8GB)](https://openhardware.directory/r?to=https%3A%2F%2Fwww.adafruit.com%2Fproduct%2F4094&ref=openhardware.directory&product=raspberry-pi-compute-module-3&source=md-export) — $25.00 - [Adafruit (CM3+ Lite)](https://openhardware.directory/r?to=https%3A%2F%2Fwww.adafruit.com%2Fproduct%2F4093&ref=openhardware.directory&product=raspberry-pi-compute-module-3&source=md-export) — $25.00 - [Adafruit (CM3+ Dev Kit)](https://openhardware.directory/r?to=https%3A%2F%2Fwww.adafruit.com%2Fproduct%2F4092&ref=openhardware.directory&product=raspberry-pi-compute-module-3&source=md-export) — $99.00 ## Resources - [product](https://openhardware.directory/r?to=https%3A%2F%2Fwww.adafruit.com%2Fproduct%2F4094&ref=openhardware.directory&product=raspberry-pi-compute-module-3&source=md-export) - [docs](https://openhardware.directory/r?to=https%3A%2F%2Fdatasheets.raspberrypi.com%2Fcm3%2Fcm3-plus-datasheet.pdf&ref=openhardware.directory&product=raspberry-pi-compute-module-3&source=md-export) - [schematics](https://openhardware.directory/r?to=https%3A%2F%2Fdatasheets.raspberrypi.com%2Fcm3%2Fcm3-plus-io-board-schematics.pdf&ref=openhardware.directory&product=raspberry-pi-compute-module-3&source=md-export) - [github](https://openhardware.directory/r?to=https%3A%2F%2Fgithub.com%2Fraspberrypi&ref=openhardware.directory&product=raspberry-pi-compute-module-3&source=md-export) ## Tags `raspberry-pi`, `compute-module`, `cm3plus`, `bcm2837`, `cortex-a53`, `sodimm`, `linux`, `industrial`, `sbc` ## Images ![Raspberry Pi Compute Module 3+](https://nbg1.your-objectstorage.com/openhardware-directory/entities/raspberry-pi-compute-module-3-plus/42137dadb56f.jpg) ![Raspberry Pi Compute Module 3+](https://nbg1.your-objectstorage.com/openhardware-directory/entities/raspberry-pi-compute-module-3-plus/0c100cbc516e.jpg) ![Raspberry Pi Compute Module 3+](https://nbg1.your-objectstorage.com/openhardware-directory/entities/raspberry-pi-compute-module-3-plus/98edf355bb06.jpg) --- [View full device page](https://openhardware.directory/devices/raspberry-pi-compute-module-3)
