Product details

This is a LoRaWAN weight sensor node based on the ESP32 from LilyGo. With this module, you can read data from up to four external weight sensors via the LoRa network. Thanks to the ESP32, the board has Wi-Fi and Bluetooth connectivity. The weight sensors are connected via a 4-pin (2.54 mm) connector. The board can communicate through all common interfaces such as I2C, SPI, UART, and I2S. The module is powered via a crimp terminal with 5-12V. Programming is done through a USB-C port.

Note: Since the module does not have a USB to Serial chip, you will need a T-U2T USB to TTL adapter for programming. If you have already purchased this along with another display, you can certainly use it for this one as well. The T-U2T USB to TTL automatic downloader is not included with the display. Additionally, the weight sensors are not included and must be purchased separately.
