The Raspberry Pi Model B+ is an updated revision of the original Raspberry Pi Model B, featuring improved power supply design, more USB ports, expanded GPIO, and a more convenient microSD card slot — all in the same compact form factor.
Powered by the same Broadcom SoC running at 700 MHz with 512 MB RAM, the B+ is fully software-compatible with earlier models while offering significant hardware improvements for easier integration into projects and enclosures.
Key Improvements Over Model B
- 4 USB Ports – Double the connectivity (up from 2)
- 40-Pin GPIO Header – Expanded from 26 pins; first 26 pins retain the original layout
- Improved Power Supply – Dual buck converters with polarity protection, 2 A fuse, and hot-swap protection
- MicroSD Card Slot – Push-push socket replaces the full-size SD holder
- 4 Mounting Holes – Rectangular layout for secure enclosure mounting
- Composite Video Integrated – NTSC/PAL output via 4-pole 3.5 mm A/V jack

Jargon buster
Plain-language definitions for the technical terms used above.
- 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.
- Hot-swap
- Hot-swap means changing or connecting a power source while the circuit is still running. It matters when you want a project to keep operating during battery changes, supply swaps, or plug-in power transitions.
- microSD card
- A microSD card is a small removable memory card used to store files such as audio tracks. For this product, the card is where the sound files live, so its capacity and formatting can affect how many sounds you can use.
- RAM
- RAM is temporary memory used while a device is running, and its contents are lost when power is removed. A “Run in RAM” mode is useful for testing settings without permanently programming the module, but it may not support every feature.
