Pi 2

The Raspberry Pi 2 Model B is the second generation Raspberry Pi released in February 2015. Compared to the Pi 1 it has a 900MHz quad-core ARM Cortex-A7 CPU and 1GB RAM ⁴.

Pi 3

The third generation Raspberry Pi 3 replaced the Raspberry Pi 2 Model B in February 2016, now featuring a 1.2 GHz 64-bit quad-core ARMv8 CPU, 802.11n Wireless LAN, and Bluetooth 4.1 ⁵.

Pi 4

The Raspberry Pi 4, released in June 2019, comes with a 1.5 GHz, quad-core Cortex-A72 ARMv8 CPU, up to 4GiB DDR4 RAM, USB 3 ports, Gigabit Ethernet, 802.11ac (2.4 / 5 GHz) WLAN, Bluetooth 5.0, dual micro HDMI ports, and a 500 MHz VideoCore VI GPU ⁶.

Chess Projects

Various portable chess engines, notably Stockfish ⁷, were ported to the Pi, even suitable to build a dedicated chess computer along with self-made ⁸ ⁹ or commercial sensory boards ¹⁰. Xu Ji, Bora Mollamustafaoglu and Gun Pinyo, three students at Imperial College, London, wrote their own ARM7 assembler, and an own chess game written in it ¹¹ ¹².

Gavon

Josu Bergara Ede has developed a new portable chess system based on the Raspberry Pi called Gavon ¹³.

Jaguatirica

Lourenço Araujo de Oliveira Junior is working on a chess entitity for a Pi cluster dubbed Jaguatirica ¹⁴.

PicoChess

Jean-François Romang's PicoChess is a dedicated chess computer based on Stockfish on Raspberry Pi and the DGT Board ¹⁵ .

PuppetMaster

PuppetMaster by Folkert van Heusden is a multiple-brain incarnation of DeepBrutePos, running on a system with an UDOO computer ¹⁶ and seven Raspberry Pi calculating nodes ¹⁷ ¹⁸.

Embla Board

Embla Board by Folkert van Heusden is a self made chess computer board based on a Raspberry Pi 3 incorporating Folkert's engine Embla ¹⁹ ²⁰, new versions tested in a Pi cluster. Raspberry Pi cluster testing new Embla versions ²¹

DGT Pi

DGT Pi is a commercial dedicated chess computer expansion hardware by Digital Game Technology for their DGT Board integrated into a DGT3000 digital chess clock, released in October 2016 ²². DGT Pi consists of a Raspberry Pi 3 with built-in Bluetooth and Wi-Fi functionality. Multiple chess engines are included.

Raspberry Turk

The Raspberry Turk is a chess playing robot developed by Joey Meyer, programmed almost entirely in Python to run on a Raspberry Pi incorporating aspects of computer vision, data science, machine learning, robotics, and 3D printing ²³. The software is available under the MIT license, published on GitHub in March 2017 ²⁴.

Caddell Chess

Caddell Chess by Rohn Blake is a dedicated chess system using a Raspberry Pi 3 Model B+ with touchscreen as an UCI compliant chess graphical user interface. Caddell Chess was released in March 2021 ²⁵.
