It provides dual Ethernet ports (1 Gbps + 2.5 Gbps), M.2 NVMe storage, dual HDMI 4K output, and a wide 7-36V input range, making it suitable for industrial IoT gateways, network appliances, edge computing, and digital signage. ## Networking The dual Ethernet configuration pairs a native 1000 Mbps Gigabit port with a USB-to-2.5G Ethernet controller for the second 2.5 Gbps port. This makes the board well-suited for network routing, firewall, or gateway applications where high-throughput dual-homed networking is required. ## Storage & Expansion An M.2 M KEY slot supports PCIe Gen2/Gen3 x1 NVMe SSDs in 2280, 2260, 2242, and 2230 form factors. NVMe boot is supported, enabling fast storage without SD cards. A TF card socket is available for CM5 Lite variants that lack onboard eMMC. ## Display & Camera Two HDMI ports provide dual 4K display output for kiosk or digital signage applications. Two 22-pin 0.5mm FFC MIPI interfaces support both CSI camera and DSI display connections (4-lane MIPI each). ## I/O & Interfaces USB connectivity includes one USB 3.2 Gen1 port (5 Gbps, 2A max), two USB 2.0 ports (480 Mbps shared, 2A total), and a USB Type-C port for flashing and power delivery. The standard 40-pin GPIO header provides access to I2C, I2S, SPI, UART, and general-purpose pins. ## Security & Industrial Features An onboard ATSHA204 encryption chip (I2C address 0x64) and CAT24C32 EEPROM (I2C address 0x50) provide hardware-based security and device identification for industrial deployments. The wide 7-36V DC input range accommodates diverse power environments. A 5V 4-pin JST-SH PWM fan header supports active cooling. ## Physical Design The base board measures 109.0 x 91.5mm. An optional metal enclosure (114.6 x 91.5 x 32.9mm) includes a CM5-FAN-4010-5V cooling fan with wall-mount and rail-mount support for industrial installation. ## Where to Buy - [Waveshare](https://openhardware.directory/r?to=https%3A%2F%2Fwww.waveshare.com%2Fcm5-dual-eth-base.htm&ref=openhardware.directory&product=waveshare-cm5-dual-eth-base&source=md-export) — $54.99 ## Resources - [product](https://openhardware.directory/r?to=https%3A%2F%2Fwww.waveshare.com%2Fcm5-dual-eth-base.htm&ref=openhardware.directory&product=waveshare-cm5-dual-eth-base&source=md-export) - [wiki](https://openhardware.directory/r?to=https%3A%2F%2Fwww.waveshare.com%2Fwiki%2FCM5-DUAL-ETH-BASE&ref=openhardware.directory&product=waveshare-cm5-dual-eth-base&source=md-export) - [schematics](https://openhardware.directory/r?to=https%3A%2F%2Ffiles.waveshare.com%2Fwiki%2FCM5-DUAL-ETH-BASE%2FCM5-DUAL-ETH-BASE-Sch.pdf&ref=openhardware.directory&product=waveshare-cm5-dual-eth-base&source=md-export) - [datasheet](https://openhardware.directory/r?to=https%3A%2F%2Fdatasheets.raspberrypi.com%2Fcm5%2Fcm5-datasheet.pdf&ref=openhardware.directory&product=waveshare-cm5-dual-eth-base&source=md-export) ## Tags `raspberry-pi`, `compute-module-5`, `cm5`, `carrier-board`, `dual-ethernet`, `2.5g`, `nvme`, `industrial`, `iot-gateway`, `open-source` ## Images ![Waveshare CM5-DUAL-ETH-BASE](https://nbg1.your-objectstorage.com/openhardware-directory/entities/waveshare-cm5-dual-eth-base/126c6128f33f.jpg) ![Waveshare CM5-DUAL-ETH-BASE](https://nbg1.your-objectstorage.com/openhardware-directory/entities/waveshare-cm5-dual-eth-base/98b1f63190bb.jpg) ![Waveshare CM5-DUAL-ETH-BASE](https://nbg1.your-objectstorage.com/openhardware-directory/entities/waveshare-cm5-dual-eth-base/e0742c7da874.jpg) --- [View full device page](https://openhardware.directory/devices/waveshare-cm5-dual-eth-base)
