Raspberry Pi Compute Module 4 Mini Base Board

This Base Board provides you with the Raspberry Pi Model B form factor of the Raspberry Pi CM4 :)

It enables you to evaluate the Raspberry Pi CM4 (both wireless and non-wireless)

It is also compatible with CM4 with eMMC or CM4 Lite (without onboard eMMC). The Mini Base Board extended out the Raspberry Pi standard 40-pin GPIO onto color-coded headers.

Compact yet complete with many practical and useful peripherals/ports:

• CSI
• DSI
• FAN (Only 5V fan)
• Full-Size HDMI
• USB
• RJ45 Gigabit Ethernet
• Micro SD Card Slot
• M.2 Slot

Note: Only support NVME SSD M.2 Key M, 2230 and 2242, this board DOES NOT support M.2 SATA III SSD.

6. HDMI0 connector:
   1. HDMI0 port supports up to 4K 30fps output
7. USB 2.0 ports:
   1. 2 x USB 2.0 ports, for connecting sorts of USB devices
   2. USB2.0 is closed by default, if you need to open it, you need to add dtoverlay=dwc2,dr_mode=host
8. Gigabit Ethernet connector
   1. Gigabit Ethernet RJ45 connector, with 10 / 100 / 1000M network support
9. M.2 indicator:

10. ACT indicator:
    1. Indicating the operating status of Raspberry Pi
11. PWR indicator:
    1. Indicating the status of Raspberry Pi power supply
12. BOOT selection:
    1. ON: CM4 would be booted from the USB-C interface
    2. OFF: CM4 would be booted from eMMC or Micro SD card
13. 40PIN GPIO header:
    1. Raspberry Pi Standard 40-pin GPIO, in color-coded headers
14. Micro SD card slot:
    1. For connecting a Micro SD card with a pre-burnt image (Lite variant ONLY)
15. HDMI1 FFC connector:
    1. HDMI1 port supports 4K 30fps output
    2. Requires another adapter board (optional)
16. USB 2.0 FFC connector:
    1. Can be connected through an adapter
    2. Requires another adapter board (optional)
17. FE1.1S
    1. USB HUB chip, expanding one USB port to 4x ports
18. M.2 slot:
    1. supports sorts of NVME SSD, or communication modules with PCIe M.2 KEY-M interface
    2. NVME SSD 2230 and 2242 ONLY
    3. Not Compatible with SATA M.2 SSD
