LILYGO TTGO ESP32 HX711 4 Channel IOT T-weigh Lora Weighing Module

Introducing the LILYGO TTGO ESP32 HX711 4 Channel IOT T-weigh Lora Weighing Module! This amazing product is perfect for hobbyists looking to create their own projects that need strong connectivity and fast digital communication. With its MCU, T-Micro32, and 4Mb of Flash, this board ensures optimal performance as well as reliable operation. It can communicate over UART, SPI, I2C, CAN, I2S, or SDIO and comes with Wi-Fi: 802.11 b/g/n/, BLE V4.2 and LoRa frequency band 868/ 915 support giving you even greater flexibility when it comes to wireless connectivity. 

Ever wanted to build your own LoRaWAN-connected weighing scale? Me neither, but apparently those types of products already exist for logistics and inventory management, and LilyGO’s latest ESP32 board – the TTGO T-Weigh – is designed for this exact purpose with a Semtech SX1272-based LoRa module and four HX711-24-bit ADC chips.

The board can handle up to four scales that transfer weight data over WiFi, Bluetooth, or LoRaWAN, and should be useful in applications that require weighing goods or products where there are limited connectivity options including logistics and farming.
