Source: Digi-Key ElectronicsIn this short video, you will learn about the major differences between the Raspberry Pi 3B+ and the new Raspberry Pi 3A+. Differences include physical size, the number of ports, Ethernet and memory size. Similarities include the CPU, 40-pin headers, CSI camera port, 4-pole stereo and the display port.

The Raspberry Pi 3 Model A+ is a more compact and reduced-price version of the 3 Model B+. Of course, with the smaller footprint comes a few compromises.

The new A+ version is missing a few items that the B+ has.

  1. Half the memory – 512 mB instead of 1 GB
  2. One USB as opposed to four
  3. No ethernet ports

Don’t worry though, the new Pi 3 Model A+ still includes these key features that you’ve grown to know and love.

  1. Same 5 V, 2.5 A micro USB power input
  2. Same Broadcom BCM2837B0, Cortex-A53 (ARMv8) 64-bit SoC @ 1.4GHz CPU
  3. Extended 40-pin GPIO header
  4. CSI camera port
  5. HDMI
  6. 802.11.b/g/n/ac WLAN
  7. Bluetooth 4.2/BLE
  8. DSI display port
  9. 4-pole stereo output

According to the Pi Foundation, this will be the final Pi of its kind. So, if you have a project needing a smaller footprint Pi and can feasibly accept the differences, this is the perfect solution for you. Happy Making!
