The Raspberry Pi 3 Model A+ is a compact, cost-effective single-board computer featuring the same 64-bit quad-core Broadcom BCM2837B0 processor as the Raspberry Pi 3 B+, running at 1.4 GHz. It includes dual-band Wi-Fi (2.4 GHz and 5 GHz) and Bluetooth 4.2/BLE in a smaller form factor.

Compared to the B+ model, the A+ removes the Ethernet port and three of the four USB ports, retaining a single USB 2.0 port. The 40-pin GPIO header, CSI camera connector, and DSI display connector remain identical, maintaining compatibility with existing HATs, cameras, and peripherals.
