The ESPGateway Ethernet comes with a ESP32 WROVER-IE module with IPEX antenna connector. The ESP32 can display the status by using four WS2812b-3535 addressable RGB leds.
You can program the ESP32 over a USB-C plug connected to a CH9102F serial-to-UART chip.
The ESPGatway Ethernet can be used for a wide range of applications:
- PAX (person) counter based on beacon signals of smartphones
- WiFi Gateway for the ESPNow protocol to save energy in battery-powered devices
- Bluetooth gateway to communicate with BLE devices
We wrote a blog post describing these ideas in more detail here.
