Rev2: common questions
What microcontroller does the Rev2 use?
The Rev2 is built around the C2913201, from the ESP32 family.
How big is the Rev2 PCB?
The Rev2 measures 251.6 × 177.8 mm, has 2 copper layers and is 1.69 mm thick.
How many components are on the Rev2?
1054 components, from 18 distinct parts. The full bill of materials is listed on this page.
Where can I download the Rev2 design files?
From the itsmevjnk/MelbourneTrainTracker repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Rev2 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 Rev2 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.
