Build a weighing prototype with OpenScale’s combined microcontroller, ADC and USB-to-serial hardware. It supports standard four- or five-wire load cells or a bridge formed from four load sensors. An ATmega328P handles the board’s processing, while a Mini-B USB connection provides a computer interface for reading the measurements.
