The Raspberry Pi has come a long way since hitting the scene in 2014. Since then, it has found its way into a plethora of applications. From basic tinkering and educational purposes to specialized scientific and manufacturing applications, it has become a go-to for those looking at an affordable means of getting things done. Meanwhile, in the last six years, the Raspberry Pi has become a full-fledged computer. The latest compute module has just been announced, and it has many new modern features.

The newly redesigned board has even more options now. Starting at only $25, many would be hard pressed to find a lower-cost solution. From DDR4 memory to 4K HEVC decoding, this little board has a lot going for it. How about a 64-bit processor to use modern apps? They now have Wi-Fi options as well, including the latest Bluetooth. Wi-Fi can be achieved using either the built-in antenna or a separate antenna kit.

  • Gigabit Ethernet jack
  • Two USB 2.0 ports
  • MicroSD card socket (only for use with Lite, no-eMMC Compute Module 4 variants)
  • PCI Express Gen 2 x1 socket
  • HAT footprint with 40-pin GPIO connector and PoE header
  • 12V input via barrel jack (supports up to 26V if PCIe unused)
  • Camera and display FPC connectors
  • Real-time clock with battery backup

As a child of the 70’s I was part of the many who became enthralled by the video arcade invasion of the 1980’s. Saving money from various odd jobs I purchased my first computer from a friend of my dad, a used Atari 400, around 1982. Eventually it would end up being a lifelong passion of upgrading and modifying equipment that, of course, led into a career in IT support.
