The Raspberry Pi 3 Model A+ is a compact single-board computer featuring a 64-bit quad-core 1.4GHz Broadcom BCM2837B0 processor, dual-band wireless LAN (2.4GHz and 5GHz), and Bluetooth 4.2/BLE. It shares the same smaller mechanical footprint as the original Pi 1 Model A+, making it ideal for embedded and space-constrained projects.
With 512MB of RAM, a full-size HDMI port, and a single USB 2.0 port, the 3A+ is well-suited for lightweight applications such as media players, IoT gateways, and dedicated controller projects where the full connectivity of the Model B+ isn't required.

Jargon buster
Plain-language definitions for the technical terms used above.
- BLE
- BLE stands for Bluetooth Low Energy, a Bluetooth mode designed for low power use and broad compatibility with modern phones and computers. It connects well to battery-powered and mobile devices, including Apple hardware, though it behaves differently from Bluetooth Classic and its serial-style profiles.
- GPIO
- General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.
- HDMI
- HDMI is a common digital video and audio connection used by computers, media players, and many displays. If a display kit has HDMI input, it is usually much easier to test with a single-board computer because it can act like a normal monitor.
- IoT
- Short for Internet of Things, meaning physical devices that connect to networks or the internet to send data or be controlled remotely. It matters if you want projects such as connected sensors, remote controls or classroom data-logging activities.
- RAM
- RAM (random-access memory) is fast, temporary memory a device uses for working data while it is running; in its common volatile form, its contents are lost when power is removed. Some devices offer a mode that applies settings to RAM only, which is handy for testing changes temporarily because they are not stored permanently and disappear at power-off.
- single-board computer
- A complete computer built onto one circuit board, usually including the processor, memory, ports, and connectors. This matters because accessories like heatsinks must match the board’s layout and mounting holes to fit properly.
- USB 2.0
- USB 2.0 is a widely used wired standard for carrying both data and power between a device and a computer or other compatible host, with data rates up to 480 Mbps. It indicates the kind of port a device uses and that it should work with most modern and many older computers.
