## Description

The SparkFun OpenScale is an open-source weight measurement board designed for load cells. Simply connect a four-wire or five-wire load cell of any capacity, plug into USB, open a serial terminal at 9,600 bps, and you'll immediately see mass readings. A built-in serial menu lets you configure calibration values, sample rate, timestamps, and units of precision. Designed for static and continuous weighing applications — such as monitoring systems, conveyor belts, and long-term data logging — the OpenScale can operate unattended for months. An on-board TMP102 temperature sensor records ambient temperature alongside weight data. Key Features HX711 24-Bit ADC – High-resolution load cell amplifier for accurate weight measurement ATmega328P Microcontroller – Handles serial communication and configuration TMP102 Temperature Sensor – Records ambient temperature alongside weight data FT231 USB-to-Serial – Mini-USB connection for data output Configurable Baud Rate – 1,200 to 1,000,000 bps (default 9,600 bps 8-N-1) Serial Configuration Menu – Set calibration, sample rate, timestamps, and precision via terminal Multi-Cell Support – Works with single load cells or four sensors in Wheatstone bridge configuration Ideal For DIY weigh scales and measurement systems Long-term unattended weight monitoring Industrial and conveyor belt weighing Data logging with OpenLog or similar serial loggers Package Contents 1× SparkFun OpenScale Board Resources OpenScale Applications & Hookup Guide
