Raspberry Pi 3 Model A+
A more minimalist board than the Raspberry Pi 3 Model B+. It has a 64-bit quad core processor running at 1.4 Ghz, dual-band 2.4 Ghz, 5 Ghz WLAN and Bluetooth 4.3/BLE.
It has only one USB port and no Ethernet jack. The USB port is set in and sticks up quite a bit compared to the very slim Pi Zero, if you're using HATs or bonnets with the Pi A+ that sit flat, please use some tape or a GPIO spacer to avoid shorts between the USB port and any pads on the bonnet.
