README
READMEThis is a model diesel locomotive control stand (more or less typical of a 2nd generation diesel locomotive).
Files / Directories:
2ndGenLocoControlStand.dxf, 2ndGenLocoControlStand.gcad, and 2ndGenLocoControlStand.tcl relate to the 3D model of the front panel (based on a Hammond Manucafturing RL6685 enclosure).
The ESP32ControlStand directory contains the ESP32 (TTGO-T1) based design, the electronics are in KiCad form (Version: 2013.06.11). The ESP32ControlStand/ESP32ControlStand_Node directory contains the OpenMRN code (C++, Arduino style using the OpenMRNLite library).

Questions
How big is the ESP32ControlStand PCB?
It measures 184.1 × 144.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ESP32ControlStand use?
120 parts, built around the LM2574N-5.0, MCP23017-E/SS, TBD62083APG and RJ45. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the ESP32ControlStand KiCad files?
From the RobertPHeller/2ndGenLocoControlStand repository on GitHub, at the commit this page was made from: the board is ESP32ControlStand/ESP32ControlStand.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESP32ControlStand design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
