About the TVBGone PCB

TVBGone is an open source AVR/Arduino PCB design by curiouselectric, published on GitHub under the MIT license. It is a 2-layer board measuring 55 × 33 mm, with 17 components from 12 distinct parts.

Its main chip is the ATTINY85, from the AVR/Arduino family. By type, the board carries 5 transistors, 4 resistors, 3 connectors, 2 capacitors, 1 IC and 1 crystal.

From the project

TV-B-Gone Design Files

The TV-B-Gone was conceived by hack-hero Mitch Altman. It is designed emit the 'OFF' code for the majority of TVs in Europe and the US. Basically it is a TV remote control which only has the power button. It is designed to turn off inappropriate TVs, such as unwatched ones in public spaces. It is a commercial product, but Mitch has also worked with Adafruit industries to have an open-source design.

TVBGone: common questions

What microcontroller does the TVBGone use?

The TVBGone is built around the ATTINY85, from the AVR/Arduino family.

How big is the TVBGone PCB?

The TVBGone measures 55 × 33 mm, has 2 copper layers and is 1.6002 mm thick.

How many components are on the TVBGone?

17 components, from 12 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 TVBGone design files?

From the curiouselectric/TVBGone 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 TVBGone design in my own project?

Yes, under the terms of its MIT license, which curiouselectric chose for the repository.

Can I test firmware for the TVBGone without the hardware?

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