Raspberry Pi 3 Model A+

Raspberry Pi 3 Model A+, the newest member of Raspberry Pi range, was released by Raspberry Pi Foundation last year. Back in 2014, the original Raspberry Pi Model B+ came out, closely followed by a cut-down Model A+. However, the A form-factor versions of later Raspberry Pi 2 or 3 was missing. Now, the Raspberry Pi 3 Model A+ extends the Raspberry Pi 3 range into the A+ board format.
With standard A+ size, this Raspberry Pi 3 model A+ inherits most features of its big brother, Raspberry Pi 3 B+. It integrates a 1.4 GHz 64-bit quad-core processor and features dual-band 2.4GHz and 5GHz wireless LAN, Bluetooth 4.2 and improved thermal management.
Compared with Pi 3B+, the new Pi 3A+ has smaller RAM and drops USB hub and Ethernet controller, which makes it able to provide a lower price as well as keep a small body. Meanwhile, it is compatible with Pi 1A+, for Pi 1A+ fans or someone who wants smaller Raspberry Pi main-board, this Pi 3 A+ would be the best choice for you!
