Mtt final: common questions

What microcontroller does the Mtt final use?

The Mtt final is built around the ESP32_DevKit_V1_DOIT, from the ESP32 family.

How big is the Mtt final PCB?

The Mtt final measures 423.5 × 392.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Mtt final?

757 components, from 15 distinct parts. The full bill of materials is listed on this page.

Where can I download the Mtt final design files?

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

Can I use the Mtt final design in my own project?

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

Can I test firmware for the Mtt final without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
