This is the Raspberry Pi 3 Model A+ released in November 2018. Like the previous A+ format, this board is the 'lite' version of Pi 3 B+ with a more compact footprint. The major differences are it comes with 512MB RAM on board instead of 1GB, single USB 2.0 port instead of four and no ethernet port. The Pi 3 A+ is using the same processor as the Pi 3 B+. This board also has wireless connectivity making it great for IoT applications.
Why would you consider Pi 3 A+?
The cost is lower if you do not need the extras
Lower power consumption making it ideal for battery and solar powered applications
Lighter weight - about 23g lighter than Model B+, a plus point should you want to use it in a drone, robot, high altitude balloon or rocket.
Smaller footprint - around 2cm shorter than the Model B+, great for embedded applications
