The Raspberry Pi Foundation has released the Raspberry Pi Model A+ , a lower-cost variant of the Model B+ released back in July.
Available now for just $20, the Model A+ uses the BCM2835 application processor and has 256MB RAM, but it is smaller (65mm in length, versus 86mm for the Model A), consumes less power, and inherits the improvements already made to the Model B+. These include the larger GPIO header, which has grown to 40 pins, making the Model A+ compatible with the HAT standard for add-on boards. In addition, the
the old friction-fit SD card socket has been replaced with a push-push micro SD version, and the new audio circuit incorporates a dedicated low-noise power supply.
You can buy the Model A+ today from Farnell in the UK, and MCM in the US.
The Raspberry Pi debuted back in 2011 with the ambitious idea of producing an ARM GNU/Linux box for $25, so it?s good to see another $5 off the cost while it is still built in the UK.
