Prototype Compute Module systems with the Raspberry Pi Compute Module 5 Dev Kit
The Raspberry Pi Compute Module is a comfortable way to integrate Raspberry Pi process computers into industrial electronics. This kit simplifies getting started, thereby leading to significantly faster solution deployment.
Mounting classic process computers on top of an application PCB is an interesting challenge. Products such as the Raspberry Pi Compute Module 5, shown in the figure below, help circuit designers work around this problem by providing a more robust way to attach the compute module to the PCB.
The high degree of integration makes the initial start-up more interesting. With the SC1755, developers are provided a one-stop shop for starting Raspberry Pi development.
Advanced Interfaces Require PCB Connections
PCB antennas, such as those found on the normal Raspberry Pi family, are useful for classic single-board computer usage. When the whole system has to be placed inside a case, the situation looks different---having access to an external antenna or an antenna connector means that the antenna can be placed in the optimal position for ideal RF performance. Similar questions apply to various interfaces, which the compute module exposes via its board-to-board connectors.
The development kit addresses this with a variety of peripheral devices. Firstly, it provides a Compute Module 5 IO breakout board. This PCB, known under the SKU SC1751, accepts a compute module and provides the usual interfaces from classic Raspberry Pi systems.
In addition to that, the whole assembly can be enclosed inside a SC1753 case for additional rigidity.
Accelerated Start-Up via Tools for Thermal Management
Modern process computers provide an eye-watering amount of processing power. This amount of compute performance means that the boards can heat up. In the case of the CM5, this is addressed via a variety of thermal accessories. Here, the Raspberry Pi Cooler for Raspberry Pi Compute Module 5 (aka SC1752) is included---it mounts on top of the Compute Module to improve heat dissipation.
In addition, Raspberry Pi Trading provides an antenna for wireless reception and a few additional cables to enable workstation-process-computer communication.
Finally, initial development is aided via Compute Module 5. The CM5104032 version is a mid-range option with a Wi-Fi transmitter, 4 GB of RAM, and 32GB of eMMC permanent memory. While not an absolute top-of-the-line member, developers can immediately get their Raspberry Pi Compute Module-based solution up and running.
The kit includes a 27-watt Raspberry Pi power supply, particularly the SC1154. This connects directly to the I/O board and ensures the powering of both the Raspberry Pi Compute Module and any peripherals that might need to be attached to complete the sensor system.
Conclusion
If a Raspberry Pi Compute Module-based solution is to be prototyped, the SC1755 is the fastest way to get started. Thanks to the vast array of included components, it provides a one-stop shop for all kinds of evaluation. When done, design-out is simplified due to the close similarity and the availability of the design files for the various components constituting this Raspberry Pi 5 Compute Module kit.
