About the ESP32-S3-WROOM-ControlStand PCB

ESP32-S3-WROOM-ControlStand is an open source ESP32 PCB design by RobertPHeller, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 127 × 118.9 mm, with 84 components from 67 distinct parts.

Its main chip is the TC1263-3.3VOATR, from the ESP32 family. Other key parts include the USBLC6-2SC6, MCP73871, ESP32_S3_WROOM-1 and TCA8418. By type, the board carries 23 resistors, 20 switches, 15 connectors, 10 capacitors, 9 diodes and 5 ICs.

From the project

Model 2nd Generation Diesel Locomotive Control Stand

This is a model diesel locomotive control stand (more or less typical of a 2nd generation diesel locomotive).

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).
