Production of the circuit board

At the beginning of 2016 our self-developed circuit board was kindly manufactured by Schneider Electric free of charge. The board mainly is used to provide 6 different voltage levels which are necessary for properly operating the sensors. Furthermore, it converts analog signals into digital ones. This must be done quite precisely because small differences result in huge aberrations. Regarding the scales for example, a voltage drift of 0.000002V is equivalent to a 10g difference in weight. Furthermore, several sensors for system surveillance are included, such as charging voltage, two current sensors and the barometer. 13 of the 24 produced circuit boards are in use now. 8 of the remaining ones are anticipated to be sold in the coming month and years.
