TailBoard2025: common questions
What microcontroller does the TailBoard2025 use?
The TailBoard2025 is built around the ATmega328PB-A, from the AVR/Arduino family.
How big is the TailBoard2025 PCB?
The TailBoard2025 measures 63 × 36.5 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the TailBoard2025?
36 components, from 24 distinct parts. The full bill of materials is listed on this page.
Where can I download the TailBoard2025 design files?
From the papurika37/KUBTSS_Board25 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the TailBoard2025 design in my own project?
The repository has no license, so all rights stay with papurika37. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the TailBoard2025 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.
