By early December, the schematic and layout for the main flat assembly were also complete.
True to the motto "small but mighty!", our printed circuit board contains not only the display but also the entire control intelligence of the system on only 90 mm x 45 mm and 6 layers.
For good readability of the operating states and the temperature, we have chosen an actively illuminated 7-segment display with 4 digits. The adjustment of the configuration to the respective wishes of the user is done via 3 keys on the device.
