◆ Overview

- CM4 Nano is an embedded computer designed for industrial applications based on Raspberry Pi Compute Module 4 (CM4 for short). It makes full use of the structural flexibility of CM4 to solve the heat dissipation problem of CPU, wireless module and PMU. The BT antenna improves the reliability of wireless communication and provides flexible expansion capabilities.
- The system can be configured into 1GB/2GB/4GB/8GB RAM and 8GB/16GB/32GB eMMC, 2.4/5.8G dual-band WiFi and Bluetooth (optional) according to different applications, and it supports external antenna.
- For application scenarios that require large data storage capacity, user can use eMMC to install the operating system and store the application data, at the same time, users can use SD card to store large user data, compare to the built-in eMMC memory, SD card can offer larger capacity and its cost is more effective.
- CM4 Nano provides alarm buzzer ,battery-powered real-time clock, , supports Gigabit Ethernet port with POE function, which is compatible with the official Raspberry Pi PoE HAT.
- The CSI and DSI interfaces of CM4 Nano are fully compatible with Raspberry Pi4 Model B. CSI supports Raspberry Pi official 8M and 12M Pixel HQ cameras, and DSI interface supports Raspberry Pi official 7" touch display. The Standard HDMI interface can output 4K HD video.
