Open Source Hardware Developed With Open Source Software *
A hardware design which includes ESP32, Ethernet, Wi-Fi, USB and serial connectivity. iot-esp-eth is suitable to use as a gateway between Ethernet, Wi-Fi and serial. When used with esp-at project, you can connect wired or wireless networks with AT commands sent to USB or serial ports. You may also operate it with custom firmware, since it is not different from a usual ESP32 development kit.
iot-esp-eth may be used as an attachment to a base board. Standalone usage with USB supply is possible as well.
ESP-IDF automatic bootloader activation is supported on USB port. This port is connected to UART0 of ESP32.
Schematic, PCB layout and antenna design are available in this repository. iot-esp-eth is compatible with many example projects at espressif github repository.
- PCB Design : KiCAD project including schematic, layout, BOM, Gerber files.
- Antenna Design : OpenEMS project for PCB antenna design including simulation scripts, figures and prototype measurements.
- Firmware : espressif/esp-at project modified to include iot-esp-eth configuration.
- Documents : Project files for diagrams and documents.
