BLE adapter to UT61E (or any other DMU with same interface), based on:
-HM11 module (or clone, I used bt05-a)
-Li-Ion cell with size of about 20x32x5 (one I used was from broken electroncis without markings)
-USB C charger module based on 4056
-Phototransistor 5mm and pull up resistor 1k
-3.3V LDO
-switch (again I used one from broken electrtonics)
