Raspberry Pi Compute Module 4 Lite (Wireless Version) - 2GB RAM

Added to your shopping cart

The Raspberry Pi Compute Module 4 represents a huge change for the Compute Module line. The biggest change being the move from the DDR2 SODIMM connector form factor to a high density connector on the bottom of the board. But true to the line, the Compute Module 4 packs all the best features of the Raspberry Pi Model B 4 into a more favorable form-factor for embedded or OEM applications.

The board includes the same 1.5GHz quad-core 64-bit ARM Cortex-A72 CPU on the Raspberry Pi 4 and is capable of 4k Video via dual HDMI interfaces. It has a single-lane PCI 2.0 express interface with dual MIPI DSI display and CSI-2 camera interfaces. For the first time, wireless capability is offered on the Compute Module line in the form of an optional 2.4GHz and 5GHz IEEE 802.11b/g/n/ac wireless LAN and Bluetooth 5.0 radio. The board supports Gigabit Ethernet PHY with IEEE 1588 support and has 28 GPIO pins, with up to 6 × UART, 6 × I2C and 5 × SPI.

This model has 1GB of LPDDR4-3200 SDRAM and no on-board Flash storage along with the wireless capability (2.4GHz and 5GHz IEEE 802.11b/g/n/ac wireless LAN and Bluetooth 5.0).

As with the Compute Module 3+, the Compute Module 4 is available with a choice of eMMC storage densities: 0GB (Lite); 8GB; 16GB; and 32GB along with a choice of DRAM densities: 1GB; 2GB; 4GB; and 8GB. As a result, there are 32 distinct variants of the product, each with its own part number. If you do not see the combination you’re looking for on our site yet, please email support@sparkfun.com.

    Do you plan to stock the mating connector?

    I ordered this version of the CM4 module, but received the 4GB RAM version with the 32GB emmc instead. I was very disappointed as the module versions with the emmc are hard to program. If you are expecting the lite version and receive the emmc versions here is how to program them. Unfortunately Windows 10 will not install the necessary drivers (https://www.raspberrypi.org/documentation/hardware/computemodule/cm-emmc-flashing.md) for the emmc module even with the "trusted source" turned off. So you will have to use either a Rpi or a Nano to program the emmc with the boot loader using "rpiboot" which is what I did. However the Ubuntu 18.04 on my Nano would not mount the emmc even though it appeared as drive "sda". So back to Windows 10. This time when I ran "rpiboot" on my Windows 10 PC it communicated with the emmc, but would not open it. However unplugging and re-plugging the USB cable into the PC brought the emmc up as a new drive (E). I was then able to use BalenaEtcher to install an image of Buster Desktop on the emmc. After completing the OS image install, don't forget to open the config.txt file and add the following so you can use the USB ports and the WiFi: "dtoverlay=dwc2,dr_mode=host" to enable the USB ports and "dtparam=ant1" if you want to use the internal antenna or "dtparam=ant2" if you are using an external antenna like I am. After you remove the emmc disable jumper on J2, connect up a monitor, keyboard and mouse to the CM4 IO board, the CM4 module should boot up like a Rpi 4B and let you configure the Buster Desktop.
