- Size : 65mm x 56mm (shorter than Raspberry Pi A/B/B+)
Building something with robotics, or any project that doesnÃâât need Ethernet networking? The lightweight, low-powerÃ Raspberry Pi A+Ã might be a great fit. Smaller and lighter than the Raspberry Pi B+, on the A+ the mounting holes are in the same place as the B+,Ã making swapping a B+ for an A+ really easy.
The A+, as the B+, is compatible with the new Hardware Attached on Top (HAT) standard for Raspberry Pi add-on boards - it has the same improved GPIO (General Purpose Input/Output) as the B+. The outline of a Model A+ and a HAT board is identical, making an A+ with aÃ HAT expansion boardÃ a sleek stack.The design is based around a Broadcom BCM2835 SoC, which includes an ARM1176JZF-S 700 MHz processor and VideoCore IV GPU.
Smaller, thinner (only 12mm, limited by the low-profile USB port) and even less power-hungry than the B+, the A+ is considerably cheaper.
What's been reduced from the B+ to the A+:
- one USB port, 256MB RAM and no Ethernet port
- otherwise electrically identical to the B+
Raspberry Pi A+ Hilights:
- benefits from the B+Ãââs improved power chain
- microSD card for booting and long-term storage
- powered via the USB data portsÃ
Raspberry Pi typically usesÃ Linux kernel based operating systems. The Raspberry Pi does not come with a real-time clock; it cannot keep track of the time of day when not powered on.Ã As alternatives, a program running on the Pi can get the time from a network time server or user input at boot time.Ã A real-time clockÃ (such as the DS1307)Ã with battery backup can be added via the IÃC interface.Ã
