What’s new in the Raspberry Pi A+?
The cheapest-yet model of the Raspberry Pi brings more pins and better audio for even less cost.
Raspberry Pi’s A+ upgrade has reached the warehouses of online shops around the world. Earlier this year in July, Raspberry Pi released the B+ upgrade of its B-Model single-board computer. Creator Eben Upton described it as the “final evolution” of the miniature computer.
It was only logical to also release a plus version of the A series, which sacrifices the ethernet connection for increased power efficiency.
Just like its predecessor, the British-made A+ comes with 256 MB of RAM (compared to 520 MB on the B+), one USB port and the same 700 MHz processor.
More pins, more efficient, more compact
The manufacturers have also made a number of interesting improvements to the specifications.
- Only 65 mm long (previously 86 mm)
- 40 GPIO pins
- Compatable with HAT (“Hardware Attached on Top”) standard for add-on boards
- 20-25% less power usage that the original model A
- A dedicated low-noise power supply for better audio
The use of the new HAT standard means that the A+ will be compatible with all add-ons that work with its bigger brother B+. The reduced power also usage improves the device’s usability for embedded projects.
Arguably the most impressive modification is the £5 reduction in price. The latest model is available for order in the UK for around £15 and in the US for $20, although it should be noted that these prices are without shipping costs.
Raspberry Pi made headlines last month when Mozilla announced its ambitions to release an official Firefox OS version for Raspberry Pi alongside Raspbian.
