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.
Hacker Friendly & Extensible
We made 16 GPIO pins available together with pins for 3V3 and GND. This allows you to extend the device and add your own sensors, displays, actuators etc. We also added a perf-board to give you space to add your own creations. And last but not least we also added a connector which is compatible with Seeeedstudio’s Grove system. Do you want to add LoRaWAN to the gateway? No problem, just connect a Grove – Wio-E5 (STM32WLE5JC) LoRaWAN module!
