The Raspberry Pi 3 Model A+ is a compact, powerful single-board computer ideal for embedded projects, education, and prototyping. Powered by a Broadcom BCM2837B0 64-bit quad‑core Cortex‑A53 processor at 1.4GHz with 512MB LPDDR2 SDRAM, it delivers strong performance in a small form factor. Built‑in dual-band 2.4GHz/5GHz 802.11 b/g/n wireless LAN and Bluetooth 4.2/BLE provide fast, flexible connectivity without extra adapters. The board includes full-size HDMI for display output, a MIPI DSI port for touchscreens, and a MIPI CSI port for camera modules, plus a 4‑pole stereo audio/composite video jack for multimedia projects. Storage is via a microSD card for operating system and data. It retains the same mechanical footprint as the original Raspberry Pi 1 Model A+, making it easy to integrate into existing designs. Powered by a 5V, 2.5A DC supply through micro USB or GPIO, it is perfect for low‑cost DIY builds, IoT devices, and commercial products where space and efficiency matter.
