BFKK Raspberry Pi CM4 4GB Lite Barebone Mini PC w/ Fan

SKU CH-37R3-YRF4D

A barebone mini PC built around a Raspberry Pi CM4 module with 4 GB LPDDR4, Bluetooth 5.0 and a cooling fan

  • CPU TypeOther
  • Quad-core Cortex-A72 at 1.5 GHz for responsive ARM computing
  • 4 GB LPDDR4-3200 memory handles multitasking smoothly
  • H.265 decode up to 4Kp60 for efficient video playback
  • Wi-Fi 802.11 ac and Bluetooth 5.0 provide wireless connectivity
  • Fan included keeps the BCM2711 SoC cool under load

Raspberry Pi CM4 4GB Lite module

This barebone mini PC is built around a Raspberry Pi Compute Module 4 with four gigabytes of LPDDR4 memory and no on-board eMMC storage. It includes a factory-fitted fan for active cooling and a fully certified radio module providing dual-band Wi-Fi and Bluetooth 5.0 connectivity. The board suits makers and developers who want a compact ARM-based platform for embedded or headless projects.

Developers needing wireless and active cooling

The integrated fan and certified 2.4 and 5.0 GHz wireless make this unit ready for enclosed deployments that require reliable thermal management and network access. Buyers who need built-in storage should look at a non-Lite Compute Module 4 variant, while projects without wireless requirements may prefer a simpler carrier board without the radio module.

Zero on-board eMMC storage

The module ships with zero gigabytes of eMMC flash, so an external boot device such as a micro-SD card is mandatory before the system can start. This single constraint decides whether the Lite version fits the intended application or whether a module with integrated flash is required.

Questions about this item

Does the barebone kit include any boot storage or do I need to add a microSD card?

The CM4 module is the Lite variant with 0 GB eMMC, so no onboard boot storage is fitted; you must provide a microSD card or a compatible carrier board with its own storage.

Which CM4 module version is used — the 4104000 or the 4108000?

The kit uses a CM4104000/CM4108000 module with 4 GB LPDDR4-3200 SDRAM, wireless LAN and Bluetooth 5.0, but without eMMC flash.

What video playback performance can I expect from the BCM2711 SoC at 1.5 GHz?

The SoC hardware-decodes H.265 up to 4Kp60 and H.264 up to 1080p60, and encodes H.264 at 1080p30, with OpenGL ES 3.1 and Vulkan 1.0 graphics support.
