A light weight wireless mouse with some standart components. I used a TP4056 charger and a standart buck converter to stepdown 3V-4.2V from the 75mah LiPo to 1.5V. This is important, otherwise you can damage the main pcb. Please check the datasheet of the buck converter if the requiered in- and output voltages are supported. I put an extra switch between the output of the TP4056 and the buck converter because the buck converter actually draw some very little current and the batterie will be empty all the time. It does'nt get overdischarged because of the DW01 chip on the charger.
With 75mah the mouse takes around 20-30min to fully charge.
In my configuration it is only 25.8 Gramm light.
Have fun building one for yourself and don't forget the mouse skates.
