About the Tenn PCB

Tenn is an open source AVR/Arduino PCB design by T3nk4I, published on GitHub under the GPL-2.0 license. It is a 2-layer board measuring 86 × 25 mm, with 30 components from 19 distinct parts.

Its main chip is the ARDUINO_NANO_V3.X, from the AVR/Arduino family. Other key parts include the L7805, DRV8871DDA and MATEKSYS_MICRO_BEC. By type, the board carries 8 connectors, 6 capacitors, 4 ICs, 4 switches, 4 resistors and 3 test points.

It belongs with the robotics & motion, power & battery and sensors designs in this gallery.

From the project

Code and Files for all the minisumo and sumo related projects I make, this repository includes codes, schematics, drawings, 3D files and more to make your own minisumo robot

The projects marked in italic are projects that are still on progress

- 3D data: I mainly use FUSION360 and FreeCAD but I upload the files in .IGES and .STL so you can use any 3D CAD software and slicer software out there to modify and/or print the parts. - PCB's: I upload the gerbers in zip format for easy fabrication, I also upload a separate gerber file and BOM for JLPCB fabrication. As for modifying the files I use Kicad which is a free and open source EDA. - Code: I use Visual Studio Code with the PlatformIO extension, but the framework I work on is the arduino framework, so you can use…

Tenn: common questions

What microcontroller does the Tenn use?

The Tenn is built around the ARDUINO_NANO_V3.X, from the AVR/Arduino family.

How big is the Tenn PCB?

The Tenn measures 86 × 25 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Tenn?

30 components, from 19 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 Tenn design files?

From the T3nk4I/Minisumo 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 Tenn design in my own project?

Yes, under the terms of its GPL-2.0 license, which T3nk4I chose for the repository.

Can I test firmware for the Tenn 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.
