Raspberry Pi Compute Module 4 I/O Mini Base Board (A) (19887)

Raspberry Pi Compute Module 4 I/O Mini Base Board A (19887) is a base board for working with the Raspberry Pi Compute Module 4, which provides the ability to use all the physical interface connectors included in the design of this computing module, including RJ45 network, HDMI, camera and display connectors, USB, and of course a full-size GPIO 40Pin with color-coded connectors. In fact, it turns out to be an assembled analog of the Raspberry Pi 4B, which also has an M.2 connector for connecting an NVME SSD.

Unlike the full and more expensive version (B) of this module, the Raspberry Pi Compute Module 4 I/O Mini Base Board B (19602 ) is not available in version (A): RTC chip, which allows you to perform RTC-related functions such as wake-up, shutdown, reboot, etc., EMC2301 fan controller, for speed control/measurement and RTC battery holder for round battery type CR1220. But due to this, the cost of this board has become more budget friendly.

Construction elements:

1. The CM4 connector is suitable for all variants of the Compute Module 4
2. Power / Programming Connector. 5 V / 2.5 A power supply or used for eMMC writing
3. MIPI DSI display port
4. Connector for connecting a cooling fan, allows you to adjust and measure the speed
5. 2x MIPI CSI camera ports
6. HDMI0 connector. HDMI0 port, supports output up to 4K 30 frames per second
7. 2 USB 2.0 ports for connecting various USB devices
8. Gigabit Ethernet RJ45 connector with 10/100/1000 Mbps network support
9. M.2 indicator to indicate the operating status of the M.2 interface
10. ACT indicator to indicate the operating status of the Raspberry Pi
11. PWR indicator to indicate the power supply of the Raspberry Pi from the power supply
12. Selecting BOOT:
    jumper shorted: CM4 will boot via USB-C interface
    jumper open: CM4 will be booted from an eMMC or Micro SD card
13. 40PIN GPIO connector
14. Slot for connecting a Micro SD card with pre-recorded data (Lite version ONLY)
15. HDMI1 FFC connector. HDMI1 port, supports 4K 30 frames per second output
16. USB 2.0 FFC connector can be connected via an adapter
17. FE1.1S. USB HUB chip that expands one USB port to 4 ports
18. M.2 slot supports various types of NVME SSDs or communication modules with PCIE M.2 KEY-M interface

Overall dimensions: 85mm x 56mm
