The Raspberry Pi 1 Model A+ is the perfect board for the minimalist Pi fan. This low-cost Pi uses the same processor as the model B+, but does away with the Ethernet jack and three of the USB Ports. This makes it lower power, less expensive and much lighter amp; smaller! it's still compatible with all Pi operating systems and software, and has the exact same 40 pin GPIO connector and camera/display sockets, so any HATs or Pi Plates or other things that plug into the model B+ will work just the same.
It also has the same HDMI, sound/composite connector and microUSB connector for power
Unlike the Raspberry Model 2, there's only one USB port and no ethernet jack but it's also significantly smaller at 65mm x 56mm if you don't include overhang from the connectors. Also, there is only 256 MB of RAM onboard instead of 512, so if you have a RAM-intensive application you may need to stick with the Model 2
Don't forget, you'll need a USB power supply with microUSB cable, and a microSD card with a Raspberry Pi OS on it (we suggest a Raspbian 4G card or NooBS 8G card)
