We are developing and producing your individual Raspberry Pi Compute Module 4 carrier board, customized exactly to your needs in regards of form factor and features.

The Raspberry PI Compute Module 4 

The Raspberry Pi Compute Module 4 (CM4) is aimed at professional and industrial applications. It features the Broadcom BCM2711 quad-core Cortex-A72 (ARM v8) 64-bit 1.5 GHz SoC, making it a powerful choice for embedded computing projects.

It is designed to be paired with a carrier board for custom application development, providing a high degree of flexibility for a wide range of applications.

The CM4 introduces a new form factor with two rows of high-speed and high-density mezzanine connectors, moving away from the SODIMM form factor of its predecessors. This change and the integration of a PCIe bus provide developers with greater flexibility and a more convenient platform for embedded development.

The CM4 is tailored for users who want to utilize the Raspberry Pi ecosystem for their own devices and embedded systems. It enables the creation of specialized PCBs or the use of pre-built carrier boards for rapid development. The module's design is aimed at developers looking for a compact, powerful computing solution that can be easily integrated into custom applications and offers a blend of performance, connectivity and flexibility unmatched by its predecessors.

Development of CM4 Custom Carrier Boards

Although there are a large number of ready-made carrier boards available for the CM4, in many cases it makes more sense to develop a customized board for your own application. This allows the features and dimensions of the board to be tailored to your application instead of the other way around.
Our company has already developed numerous carrier boards for the CM4. These include a tiny carrier board used for 4G/5G communication in civilian drones, CM4 boards for internet routers and industrial applications.

Thanks to our many years of experience, we know all the problems and quirks of the CM4 and can therefore develop perfectly functioning mainboards very quickly.

We are also very experienced in extending or replacing the connectivity options provided by the CM4. For example, the optional WLAN chip included in the CM4 is of lousy quality - more than 50 MBit/s cannot be achieved with it. We are experienced in combining the module with another WLAN chip instead. The same applies to USB: The CM4 only offers a single USB3 port, which can be expanded to up to eight USB3 ports with our boards.

Do you want wireless connectivity via LTE, 5G or LoraWAN in your project? No problem at all.

Custom Carrier Board for the Raspberry Pi CM4 Module

A competitive alternative: Radxa CM3

Since the end of 2021, the supply of CM4 by the manufacturer Raspberry Pi Foundation has been extremely unreliable - in some cases, there were no modules available on the market for several months.

Against this background, we started looking for an alternative for our customers in 2022: The Chinese manufacturer Radxa offers an alternative to the RPi CM4: The module strangely named "CM3" there is pin-compatible with the Raspberry PI CM4 (and not the RPi CM3, as one might assume from the name). It also offers features that the "original" does not have - e.g. an integrated USB3 controller.

Above all, however, the module is permanently available quickly and in large quantities, and also offers a better price/performance ratio than the module from the Raspberry Pi Foundation.

When developing your custom carrier board, we can make it both compatible to the Raspberry PI CM4 and the Radxa CM3.
