README
2-layer/README.mdESP32 Development Board PCB — Original 2-Layer Design
Overview
A custom ESP32-WROOM-32E development board designed using KiCad 9, created to explore schematic capture, component selection, PCB layout, routing, and embedded hardware design.
This is the original 2-layer PCB revision, before the later enhanced-placement redesign.
Features
- Microcontroller: ESP32-WROOM-32E with integrated Wi-Fi and Bluetooth
- USB interface: USB-C connector
- USB-to-UART bridge: CP2102N for programming and serial communication
- Power regulation: AMS1117-3.3 V regulator
- GPIO access: Expansion header for external peripherals
- Programming controls: BOOT and RESET push buttons
- User indication: Onboard LED
- PCB design: Two copper layers — front and back
Hardware Design
The board integrates the ESP32 module with its supporting power, programming, and GPIO circuitry. The design brings the main connections needed for embedded development into a custom PCB.
Design Tools
- KiCad 9 Schematic Editor
- KiCad 9 PCB Editor
- KiCad 3D Viewer
- Electrical Rules Checker (ERC)
- Design Rules Checker (DRC)
PCB Design Workflow
- Schematic capture and component selection
- Footprint assignment
- Component placement
- Two-layer PCB routing
- Copper-zone configuration
- Electrical and design-rule checks
- 3D visualization and layout review
Project Files
This directory contains the design files and visual documentation for the original revision.
- KiCad schematic (
.kicad_sch) - KiCad PCB layout (
.kicad_pcb) - PCB layout screenshots
- 3D visualization, where available
Project Status
The original PCB design was subsequently used as the basis for a four-layer redesign with enhanced placement and additional board features.
Fabrication and hardware validation should be recorded separately once completed.
Future Improvements
- Refine component placement and routing
- Review manufacturability and electrical clearances
- Fabricate and assemble the PCB
- Validate USB programming, power regulation, and GPIO functionality on hardware

Questions
How big is the Esp32 PCB?
It measures 49.5 × 52 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Esp32 use?
27 parts, built around the ESP32-WROOM-32E, SN65HVD230D, AMS1117-3.3 and NUP2105L. 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 Esp32 KiCad files?
From the Manushree-J/ESP32-Development-Board-PCB repository on GitHub, at the commit this page was made from: the board is 2-layer/esp32.kicad_pcb and its schematic 4-layer_enhanced_placement/esp32.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp32 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Manushree-J before reusing the design.
