Raspberry Pi 3B : Single-board computer with wireless LAN and Bluetooth connectivity . Raspberry Pi 3 Model B is the earliest model of the third-generation Raspberry Pi. It replaced Raspberry Pi 2 Model B in February 2016. 

The third-generation single-board computer , now in the A+ format . 1.4GHz 64-bit quad-core processor, dual-band wireless LAN, Bluetooth 4.2/BLE in the same mechanical format as the Raspberry Pi 1 Model A+ . The Raspberry Pi 3 Model A+ extends the Raspberry Pi 3 range into the A+ board format.

The speed and performance of the new Raspberry Pi 4 is a step up from earlier models. For the first time, we've built a complete desktop experience. Whether you're editing documents, browsing the web with a bunch of tabs open, juggling spreadsheets or drafting a presentation, you'll find the experience smooth and very recognisable — but on a smaller, more energy-efficient and much more cost-effective machine.

Raspberry Pi Compute Module 4 harnesses the compute power of the popular Raspberry Pi 4 Model B, bringing it to a smaller form factor suitable for integration into products. Key features include a high-performance 64-bit quad-core processor, dual-display support at resolutions up to 4K, hardware video decode at up to 4Kp60, up to 8GB of RAM, Gigabit Ethernet, USB 2.0, dual camera interfaces, and PCIe Gen 2 x1 interface. The optional dual-band 2.4/5.0GHz wireless LAN and Bluetooth 5.0 have modular compliance certification. This allows the board to be designed into end products with significantly reduced compliance testing, improving both cost and time to market. Either the onboard antenna or an external antenna kit can be used. Compute Module 4 has optional onboard eMMC of 8GB, 16GB or 32GB.

Raspberry Pi 400 is your complete personal computer, built into a compact keyboard. Featuring a quad-core 64-bit processor, 4GB of RAM, wireless networking, dual-display output, and 4K video playback, as well as a 40-pin GPIO header, it's the most powerful and easy-to-use Raspberry Pi computer yet. Raspberry Pi 400 is also available as part of a complete kit including a mouse, power supply, preloaded SD card, and more.

The Compute Module 3+ (CM3+) is a Raspberry Pi 3 Model B+ in a flexible form factor, intended for industrial applications The CM3+ Compute Module contains the guts of a Raspberry Pi 3 Model B+ (the BCM2837 processor and 1GB RAM) as well as an optional eMMC Flash device of 8GB, 16GB or 32GB (which is the equivalent of the SD card in the Pi).
