Raspberry Pi Compute Module 4 Dual Gigabit Ethernet Mini-Computer (20225)

The Raspberry Pi Compute Module 4 is not included

Raspberry Pi Compute Module 4 Dual Gigabit Ethernet Mini-Computer (20225 ) is a kit that includes a Dual Gigabit Ethernet base board and a specialized metal case with a fan to build a full-fledged microcomputer based on the Raspberry Pi CM4 compute module (the compute module itself is not included in this kit). This kit allows you to create industrial-grade projects, including stereo vision projects based on Raspberry Pi.

Thanks to the wall-mount design of the case, it can be easily mounted on almost any surface.

The base board and the computing module are protected by a sturdy two-piece metal case. The case has openings for all major interfaces, including an external antenna (antenna not included). A cooling fan is built into the case for better heat transfer.

For your convenience, all places for external interfaces are labeled.

Main elements of the base board:

1. CM4 connector is suitable for all Compute Module 4 variants
2. 40-pin GPIO connector for connecting various expansion cards
3. RJ45 Gigabit Ethernet - dual RJ45 Gigabit Ethernet, compatible with 10/100/1000M
- ETHERNET 0: original ETH CM4
- ETHERNET 1: USB extended ETH
4. USB 3.2 ports. 3x USB 3.2 Gen1 for connecting a variety of USB devices
5. HDMI connectors - 2x HDMI, supports 4K 30fps output
6. CAM - 2 MIPI CSI camera ports
7. Power connector 736 V DC
8. Dual LED indicators
- red: Raspberry Pi power indicator
- green: Raspberry Pi operating status indicator
9. Micro SD card slot for connecting a Micro SD card with a pre-recorded image (Lite version ONLY)
10. FAN connector for connecting a cooling fan, allows you to adjust and measure the speed
11. DISP0 - MIPI DSI display port
12. USB SLAVE port for writing the system image to the Compute Module 4 eMMC variants
13. RTC battery holder supports CR1220 batteries
14. RTC interrupt configuration
- PI-RUN: CM4 will reboot after RTC interrupt
- GN-EN: CM4 power down due to RTC interrupt
- D4: D4 pin is triggered by an RTC interrupt
15. The IO-VREF selection sets the CM4 IO logic level as 3.3V or 1.8V
16. FAN power supply selection (select 5V or 12V power supply to drive the fan)
17. Configuration of system functions
- BT_DIS: Bluetooth disabled, ONLY for CM4 with antenna option
- WiFi_DIS: Wi-Fi disabled, ONLY for CM4 with antenna option
- WP_DIS: Boot mode switch, used ONLY when NOT booting from eMMC or SD card
18. Selecting the RTC/FAN I2C bus
- SDA0/SCL0: I2C-10 in conjunction with CSI/DSI
- GPIO3/2: I2C-1 in conjunction with 40PIN connector
19. USB Gigabit Ethernet chip RTL8153
20. EMC2301 fan controller, allows you to adjust and measure fan speed
21. VL805 USB 3.0 HUB

Overall dimensions: 114.6mm x 91.5mm x 32.9mm
