About the Tetris PCB

Tetris is an open source RISC-V PCB design by roman-khvatov, published on GitHub under the MIT license. It is a 4-layer board measuring 33 × 91.7 mm, with 76 components from 26 distinct parts.

Its main chip is the SN74LVC1G14DBV, from the RISC-V family. Other key parts include the STP16CP05TTR, 74HCT595D, TLV70433DBVR, SZ421288N/64 and LM1085-ADJ. By type, the board carries 21 resistors, 19 capacitors, 15 test points, 11 ICs, 4 transistors and 3 switches.

From the project

Кружок робототехники RoboWay

Мы запускаем образовательный кружок робототехники RoboWay для подростков в возрасте от 12 до 18 лет (возможны исключения в зависимости от подготовки ребенка). Цель кружка — дать учащимся фундаментальные знания в области электроники, программирования и робототехники.

В отличие от большинства кружков, где используются готовые наборы и работа сводится к сборке по инструкции, в RoboWay участники будут разрабатывать и изготавливать роботов с нуля. Мы стремимся к тому, чтобы дети осознанно подходили к техническому творчеству и понимали принципы работы систем, а не просто следовали пошаговым…

Tetris: common questions

What microcontroller does the Tetris use?

The Tetris is built around the SN74LVC1G14DBV, from the RISC-V family.

How big is the Tetris PCB?

The Tetris measures 33 × 91.7 mm, has 4 copper layers and is 1.6062 mm thick.

How many components are on the Tetris?

76 components, from 26 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Tetris design files?

From the roman-khvatov/RoboWay repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Tetris design in my own project?

Yes, under the terms of its MIT license, which roman-khvatov chose for the repository.

Can I test firmware for the Tetris without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RISC-V firmware against it before you order a PCB.
