Monorail Diesel Reduced: common questions
What microcontroller does the Monorail Diesel Reduced use?
The Monorail Diesel Reduced is built around the W25Q128JVS, from the RP2040/RP2350 family.
How big is the Monorail Diesel Reduced PCB?
The Monorail Diesel Reduced measures 242.9 × 95.3 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Monorail Diesel Reduced?
188 components, from 37 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 Monorail Diesel Reduced design files?
From the KiserDesigns/Monorail repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Monorail Diesel Reduced design in my own project?
The repository has no license, so all rights stay with KiserDesigns. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Monorail Diesel Reduced 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.
