README
README.mdESP32 WiFi Network Interface Bridge
This project is a hardware solution that leverages the power of the ESP32 to bridge local communication interfaces, such as serial and (in the future) I2C, to a WiFi network. It allows devices with traditional communication interfaces to be accessed and controlled over WiFi.
Features
-
Interface Bridging: Convert and expose devices using:
- Serial interface (current implementation)
- I2C interface (planned for future releases)
-
WiFi Connectivity:
- Connect to an existing WiFi network.
- Broadcast its own Access Point (AP) for direct connections.
-
Status Indicators:
- Serial Communication:
- RX LED: Lights up when the device receives data.
- TX LED: Lights up when the device transmits data.
- WiFi Indicators:
- Connection LED: Lights up when the device is connected to an external WiFi.
- AP LED: Lights up when the device is broadcasting its own Access Point.
- Serial Communication:
Hardware Design
- Designed in KiCad.
- ESP32-WROOM-32U as the main microcontroller.
Getting Started
Prerequisites
- KiCad for viewing and editing the design files.
- A compatible power source for the board.
Setup
- Power the board: Connect the board to a suitable power source.
- Connection:
- For Serial: Connect your serial device to the designated serial port.
- For I2C (Future): Connect your I2C device to the designated I2C connectors.
- WiFi:
- Connect to an existing WiFi: Set the credentials in the firmware and upload to the ESP32.
- Use as AP: The board will automatically broadcast its AP if it fails to connect to the saved networks.
Configuration
Details about how users can configure the firmware for specific WiFi networks, adjust baud rates for serial communication, or other configuration details.
Future Enhancements
- Integration of the I2C interface.
- Firmware updates over the air.

Questions
How big is the Esp ip PCB?
It measures 50 × 25 mm and has 4 copper layers, 1.61 mm thick.
What parts does the Esp ip use?
43 parts, built around the ESP32-WROOM-32U, AMS1117-3.3, TXS0102DCU and L78M05ABDT-TR. 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 Esp ip KiCad files?
From the wolffshots/esp-ip repository on GitHub, at the commit this page was made from: the board is ESP-IP.kicad_pcb and its schematic ESP-IP.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp ip design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
