A new member of the Raspberry Pi family was unveiled this week. The Raspberry Pi 3 model A+ features the same 1.4GHz ARMv8 Cortex-A53 processor as the existing Pi 3 model B+ – but instead is more focused on the embedded market, with a smaller form factor and 512MB of RAM instead of 1GB.
Bluetooth 4.2 is supported as well as 2.4GHz and 5Ghz b/g/n/ac Wi-Fi. Power is still taken in through a micro USB connector as well as graphics coming from the usual HDMI slot and storage via a micro SD. The GPIO header as well camera and touchscreen ports are still present.
There is only one USB 2.0 port with this board, which instantly makes it less attractive for the desktop user as you’d need a USB hub to use a mouse and keyboard in conjunction with it. The Ethernet port is gone too, although Internet connectivity should be achievable through a USB-to-Ethernet adapter providing you’re using an up-to-date version of RISC OS 5.
ROOL have confirmed that RISC OS 5.26 and above is already compatible with the board should you want to tinker about with it for a lower price of £23 instead of the £32 price point that the Pi 3 B+ goes for.
Probably not an ideal board for most RISC OS users unless you have a specific requirement for a cheap, small RISC OS system – but nevertheless, this board does offer a good amount of bang for your buck.
