Bus Interfaces
Overview
The LILYGO T-Weigh pairs an ESP32 microcontroller with four HX711 24-bit analog-to-digital converters for precision load cell measurement alongside an SX1262 LoRa transceiver supporting EU868 and US915 frequency bands. This combination enables wireless scale systems that can transmit weight data over LoRa distances of several kilometers. The SX1262 delivers up to +22 dBm output power, sensitivity down to -148 dBm, and supports FSK, GFSK, MSK, GMSK, LoRa, and OOK modulations. The board runs on 4MB flash with WiFi 802.11 b/g/n and BLE 4.2 for local connectivity. Programming requires the T-U2T USB-to-TTL programmer. Available in 868 MHz (EU) and 915 MHz (US) variants.
