Raspberry Pi mini computer — new version with WiFi and Bluetooth

The third generation of the popular single-board PC is now available. Enhancements include a more powerful processor and integrated WiFi and Bluetooth features.

The Raspberry Pi is a phenomenon: The mini computer, whose components fit onto a credit card-sized board, has already been sold a million times the world over and not only inspires designers and amateurs programmers. It can be used as a powerful media player, but also as an extremely affordable office computer.

The Raspberry Pi 3 is now available. The new version works with a more powerful processor, the Broadcom BCM2837. Its four cores can be equipped with up to 1.2 GHz. The processor of the Raspberry Pi 2 Model B, introduced a year ago, works with 900 MHz. It is still available.

Wireless technology is now integrated

In addition, WiFi and Bluetooth are now integrated with the Raspberry. With the previous models, wireless connections were only possible by means of an additional dongle. The new features require more power, therefore it is necessary to have a 2.5-amp power supply.

The new model is identical to the Raspberry Pi 2 Model B when it comes to many other features: There are four USB 2.0 ports as well as an Ethernet and a HDMI connection. Two video-core-IV cores, installed in the processor, serve as a graphics processor.

They were already a feature of the Raspberry Pi 2 Model B, but at 250 MHz rather than at 400 MHz with the new model.

Older housing can also be used for the Raspberry Pi 3. Caution: If they are made from metal, they can interfere with Bluetooth and WiFi connections.

Raspberry Pi began as an experimental computer for students

In 2006, the Raspberry Foundation was established by Eben Upton, the former Head of Department of Computer Science at St John’s College in Cambridge. He wanted to develop an affordable, small computer and a simple operating system so that students could experiment and do programming without having to spend a lot of money.

Since the market launch in 2012, approximately eight million copies of the various models of the Raspberry Pi have been sold. It is the best-selling computer in the UK. We refer to a single-board computer because all elements are installed on a credit card-sized circuit board.
