Txboard: common questions

What microcontroller does the Txboard use?

The Txboard is built around the Arduino_Nano_v3.x, from the AVR/Arduino family.

How big is the Txboard PCB?

The Txboard measures 84.6 × 49.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Txboard?

24 components, from 20 distinct parts. The full bill of materials is listed on this page.

Where can I download the Txboard design files?

From the wlowi/TXos repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Txboard design in my own project?

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

Can I test firmware for the Txboard 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.
