The Model A is the low-cost variant of the Raspberry Pi. It replaced the original Model A in November 2014.
What is a Raspberry Pi?
Specification
Compared to the Model A it has:
- More GPIO pins. The GPIO header has grown to 40 pins, while retaining the same pinout for the first 26 pins as the Model A and B.
- Micro SD. The old friction-fit SD card socket has been replaced with a much nicer push-push micro SD version.
- Lower power consumption. By replacing linear regulators with switching ones we’ve reduced power consumption by between 0.5W and 1W.
- Better audio. The audio circuit incorporates a dedicated low-noise power supply.
- Smaller neater form factor. We’ve aligned the USB connector with the board edge, moved composite video onto the 3.5mm jack, and added four squarely-placed mounting holes. Model A is approximately 2cm shorter than the Model A.
Compliance
The Raspberry Pi 1 Model A has undergone extensive compliance testing, and meets the following European standards:
- Electromagnetic Compatibility Directive (EMC) 2014/30/EU
- Restriction of Hazardous Substances (RoHS) Directive 2011/65/EU
