Raspberry have released a new version of their popular Raspberry Pi "computer" for only $25. This model is cheaper than the one released earlier this year, but still has the same processor and comes with Integrated Bluetooth and WiFi connectivity.
The previous model, the Raspberry Pi Model B+, is $10 more expensive and the new model shares most of its feature set, but there are some differences. The newer model comes with 512MB of RAM rather than 1GB and features only one USB Port, whilst the older model supports four. Sticking to the connectivity side, there is no Ethernet port - and this could be a show stopper for some.
Raspberry Pi have announced support for the new device until at least January, 2023.
