LilyGo TTGo T-Weigh ESP32 4x Weight Sensor LoRa Node

This is a LoRaWAN weight sensor node based on ESP32 by LilyGo. With this module, you can read the 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 4pin (2.54mm) plug. The board can communicate via all common interfaces such as I2C, SPI, UART, and I2S. The module is powered via a crimp terminal with 5-12V. Programming is done via a USB-C port. 

Info: Since there is no USB to Serial chip on the module, you need a T-U2T USB to TTL adapter for programming. If you have already purchased this with another display, you can of course also use it for this one. The T-U2T USB to TTL automatic downloader is not included in the package of the display. Also, the weight sensors are not included and must be purchased separately.
