TaggerMainboard: common questions

What microcontroller does the TaggerMainboard use?

The TaggerMainboard is built around the MCU-ATMEGA2560-16AU(TQFP100), from the AVR/Arduino family.

How big is the TaggerMainboard PCB?

The TaggerMainboard measures 158 × 34 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the TaggerMainboard?

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 TaggerMainboard design files?

From the Infinitag/Hardware repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the TaggerMainboard design in my own project?

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

Can I test firmware for the TaggerMainboard 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.
