Raspberry Pi made a new Raspberry Pi 3 Model A+ model for $25
Today, Raspberry Pi introduces a new $25 computer that enters performance previously found on top-of-the-line $35 devices. The new model, called the Raspberry Pi 3 Model A+, uses the same quad-core 1.4GHz Broadcom processor as the high-end model B+. It also supports Bluetooth 4.2 and 2.4GHz and 5GHz Wi-Fi, making it easy to use anywhere you have a connection.
Of course, the price is $10 lower, and some specifications must be cut, that is, there is no longer an Ethernet port (Wi-Fi must be used), only 512MB of RAM instead of 1GB, it has only one USB 2.0 port instead of four. This is the same way that the Raspberry Pi last introduced a streamlined A+ model in 2014. But this time there is a huge difference that makes the new version even more powerful: the early A+ models lacked Ethernet and Wi-Fi so that they couldn’t get an Internet connection. The Pi 3 A+ has Wi-Fi so it can be used right out of the box.
