What is a Raspberry Pi?
The Raspberry Pi 4 Model B is the latest version of the low-cost Raspberry Pi computer. The Pi isn’t like your typical device; in its cheapest form it doesn’t have a case, and is simply a credit-card sized electronic board — of the type you might find inside a PC or laptop, but much smaller.
The Raspberry Pi 4 is the forth generation Raspberry Pi. It replaced the Raspberry Pi 3 Model B+ in June 2019.
Raspberry Pi 4 Model B 2GB, 4GB, 8GB
- Processor: Broadcom BCM2711, quad-core Cortex-A72 (ARM v8) 64-bit SoC @ 1.5GHz
- Memory: 2GB, 4GB or 8GB LPDDR4 (depending on model)
- Connectivity: 2.4 GHz and 5.0 GHz IEEE 802.11b/g/n/ac wireless
- LAN, Bluetooth 5.0, BLE Gigabit Ethernet, 2 × USB 3.0 ports, 2 × USB 2.0 ports.
- GPIO: Standard 40-pin GPIO header (fully backwards-compatible with previous boards)
- Video & sound: 2 × micro HDMI ports (up to 4Kp60 supported), 2-lane MIPI DSI display port, 2-lane MIPI CSI camera port, 4-pole stereo audio and composite video port
- Multimedia: H.265 (4Kp60 decode); H.264 (1080p60 decode, 1080p30 encode); OpenGL ES, 3.0 graphics
- SD card support: Micro SD card slot for loading operating system and data storage
- Input power: 5V DC via USB-C connector (minimum 3A1), 5V DC via GPIO header (minimum 3A1)
- Power over Ethernet (PoE)–enabled (requires separate PoE HAT)
- Environment: Operating temperature 0–50oC
- Compliance: For a full list of local and regional product approvals, please visit https://www.raspberrypi.org/documentation/hardware/raspberrypi/conformity.md
- Production lifetime: The Raspberry Pi 4 Model B will remain in production until at least January 2026.

The Raspberry Pi 3 is the third generation Raspberry Pi. It replaced the Raspberry Pi 2 Model B in February 2016. Compared to the Raspberry Pi 2 it has:
- A 1.2GHz 64-bit quad-core ARMv8 CPU
- 802.11n Wireless LAN
- Bluetooth 4.1
- Bluetooth Low Energy (BLE)
Like the Pi 2, it also has:
- 4 USB ports
- 40 GPIO pins
- Full HDMI port
- Ethernet port
- Combined 3.5mm audio jack and composite video
- Camera interface (CSI)
- Display interface (DSI)
- Micro SD card slot (now push-pull rather than push-push)
- VideoCore IV 3D graphics core
- The Raspberry Pi 3 has an identical form factor to the previous Pi 2 (and Pi 1 Model B+) and has complete compatibility with Raspberry Pi 1 and 2.
The Raspberry Pi Zero
The Raspberry Pi Zero V1.3:
The Raspberry Pi Zero features a BCM2835 chipset, overclocked to 1Ghz with 512MB RAM, and the same 1080p video output, so there’s plenty of oomph in that little board. It also features the same 40 pin GPIO layout as the Raspberry Pi 2/B+/A+, which you’ll need to solder your own headers to. With it’s small form factor and reduction in connectors, the Raspberry Pi Zero only uses ~ 140mA at 5V!
Unlike it’s larger brothers and sisters, the Raspberry Pi Zero has an unpopulated GPIO, unpopulated composite (RCA) header and an unpopulated reset header. There’s also no DSI screen port, no ethernet, no analogue audio and no full sized USB ports. Instead, the Pi Zero features a micro-USB power port, a micro USB OTG host port (for peripherals e.g. WiFi dongle), and a mini HDMI port for video.
HAT Compatibility Note: The Pi Zero is fully compatible with all HAT breakout boards, as it features the same 40 Pin GPIO as the Raspberry Pi 2/B+/A+
Raspberry Pi Zero Features:
- BCM2835 chipset, Overclocked to 1Ghz
- 512MB RAM
- Tiny Form Factor: 65mm x 30mm x 5mm
- Fully HAT compatible
- 40pin GPIO (Unpopulated)
- Stream and watch Hi-definition video output at 1080P
- Micro SD Slot for OS
- Tiny Current Draw ~ 140mA at 5V!
- Mini-HDMI for Video
- Micro-USB OTG Host for Data
- Micro-USB for Power
- Micro-CSI Camera Port
