Tergo mx: common questions

What microcontroller does the Tergo mx use?

The Tergo mx is built around the Raspberry_Pi_Pico, from the RP2040/RP2350 family.

How big is the Tergo mx PCB?

The Tergo mx measures 161 × 108.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Tergo mx?

130 components, from 12 distinct parts. The full bill of materials is listed on this page.

Where can I download the Tergo mx design files?

From the lukashevich-t/tergo-vial repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Tergo mx design in my own project?

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

Can I test firmware for the Tergo mx without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
