The Raspberry Pi foundation releases hardware at a snail pace and they have finally released a model A variation of the immensely popular Raspberry Pi 3.

Unlike a model 3B+ the model A reduces both the size and power requirements of the board while retaining all of the processing power of the RPi3.

This is the first Model A+ board since the original RPi and just like the previous model it trims the fat by removing the Ethernet port and has only a single USB port.

Size comparison between Model A and B

The new Pi 3 A+, which is available now, has the same quad-core system on chip as the Raspberry Pi 3 Model B+ released earlier this year. The SoC is Broadcom’s BCM2837B0, which is a 1.4GHz 64-bit quad-core Arm Cortex-A53 CPU.

The new Pi 3 A+ has 512MB of RAM, which is double the RAM of the 2014 model when it launched. The old A+ doubled its RAM in 2016.

However, the Pi 3 A+ does feature dual-band 2.4GHz and 5GHz 802.11ac wireless LAN, and Bluetooth 4.2.

The HDMI 1.3 port supports 1,080p monitors and TVs, and there’s a microUSB connector for power, as well as a four-pole stereo audio output and composite video jack.

The new model willm be very popular with prototypers, in particular in robotics and other lightweight or remote applications where both power and weight need to be reduced. With most of these applications there is no need for an ethernet ports, and peripharels such as keyboards will no be connected, instead all comunication with the board is carried out via Wi-Fi and Bluetooth.
