DFRobot PiTray Mini for Raspberry Pi Compute Module 4
The PiTray mini is a versatile carrier board or breakout board designed specifically for the Raspberry Pi Compute Module 4 (CM4), offering a neat and budget-friendly solution for various applications.
With the same outline and mounting holes as the Raspberry Pi Model B, it can be easily stacked with existing clusters, making it ideal for cluster computing projects.
The breakout board takes advantage of CM4's benefits over the Raspberry Pi 4B in industrial settings - models with embedded eMMC storage provide more reliable and faster disk I/O, while variants without WiFi and Bluetooth chips offer improved energy efficiency as these modules can be disabled to save computing resources.
This eMMC programming board serves as an excellent starter kit for CM4 users. It features a convenient eMMC boot switch that simplifies the process of flashing operating system images to eMMC, eliminating the need to figure out which pins to connect.
The board also includes a microSD card socket to support CM4 Lite models that don't have onboard eMMC storage. Designed with a minimalist approach to fit the CM4 on a business card-sized carrier, the PiTray mini focuses on essential connections - one USB 2.0 port, a full-size HDMI connector, and HAT connectors that come directly from the chip.
This streamlined design makes it an economical choice for HTPC makers, RetroPie enthusiasts, and regular Raspberry Pi users who need a similar experience to the Raspberry Pi Model B.
