The board uses ESP32 Dev Board as the microcontroller with Nextion 3.2" LCD Touch as a User Interface, made in portable form, and easy to use. Real Time Operating System (FreeRTOS) was applied to get better code structure and device performance. Weighing can be performed on 6 different objects at the same time, with adjustable maximum weighing on each channel. Use 3 pcs of IC ADS1232 as an Analog to Digital Converter. Calibration sensor feature available, with a maximum of 8 calibration points. 3 data logging models are available, which are Local via Micro SD card, Serial RS232, and logging through ThingSpeak.

Code programming is done in IDE: Platform IO - Visual Studio Code Framework: Arduino
