RedLeader PCB

This repository contains the design files for the RedLeader PCB, a custom PCB designed for a differential mobile robot. It is ready for manufacturing and assembly.

Description

This PCB is designed for a differential mobile robot with four DC motors and two encoders. It facilitates the connection of a 30-pin ESP32 with a bus from the Pololu DUAL_VNH5019 driver and connects the two encoders via JST connectors. Additionally, it provides 5V and GND outputs for peripherals, as well as outputs for encoders 3 and 4 and motors 3 and 4, allowing the unused pins of the ESP32 to be utilized, making it a multifunctional board for various robots.

Files

  • Gerber Files: Necessary for PCB fabrication.
  • Drill Files: Necessary for PCB drilling.
  • Schematic: Provides the connection diagram for components.
  • Design Details: See below for PCB specifications.

Specifications

  • Layers: 2
  • Thickness: 1.57 mm
  • Dimensions: 53.32 x 73.33 mm
  • Format: Gerber RS-274X
  • Designed with: Autodesk Fusion Electronics (v9.7.0)

Components

  • ESP32_30PIN: ESP32 module with 30 pins.
  • JST-XH-4PIN: XH Connector Top Entry - 4 positions, used for connecting the encoders.
  • PINHD-1X13: 13-position pin header, used for the bus from the Pololu driver.
  • PINHD-1X6: 6-position pin header, allows for multipurpose use by exposing more pins from the ESP32.
  • PINHD-2X5: 2x5-position pin header, used for peripherals.
  • TERM-BLK-2P: 2-position terminal block, used for connecting 12V power.

Usage

  1. Manufacturing: Upload the Gerber files and the Drill files to a PCB manufacturer (e.g., JLCPCB).
  2. Assembly: Refer to the schematic for guidance on component placement.
