The KiCad project lives in the hitov/bt-tnc repository on GitHub; these links point at the commit this page was built from.

Bluetooth KISS TNC: common questions

What microcontroller does the Bluetooth KISS TNC use?

The Bluetooth KISS TNC is built around the ATMEGA328P-AU, from the AVR/Arduino family.

How big is the Bluetooth KISS TNC PCB?

The Bluetooth KISS TNC measures 56.6 × 31 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Bluetooth KISS TNC?

55 components, from 39 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 Bluetooth KISS TNC design files?

From the hitov/bt-tnc repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Bluetooth KISS TNC design in my own project?

The repository has no license, so all rights stay with hitov. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Bluetooth KISS TNC 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.
