ESPNetLink schematics are now available on GitHub!

In this update, we’d like to share more details about ESPNetLink’s functionality. The main purpose of ESPNetLink is to serve as an LTE gateway for WiCAN PRO, but it’s also a powerful development tool for ESP32-based LTE and GPS applications. ESPNetLink is equipped with a USB multiplexer, allowing for multiple connectivity configurations:

1. Default Mode: The USB-to-Serial chip is connected to the USB port, while the BG95’s UART and USB interfaces are connected to the ESP32-S3. This setup provides the ESP32 with two simultaneous communication channels to the BG95, one for data and one for AT commands, without needing to switch modes.

2. ESP32-S3 USB Mode: The multiplexer routes the ESP32-S3 USB port directly to the USB connector. This enables custom ESP32-S3 USB device applications while still maintaining BG95 LTE connectivity over UART.

3. BG95 USB Mode: In this configuration, the BG95 USB port is connected directly to the USB connector, allowing you to update the modem firmware or perform direct testing with the module.

With all of these flexible options, ESPNetLink is not only a gateway but also a versatile platform for LTE and GPS development.
