LiOn Battery --> 3.3V - Arduino Pro Mini 8Mhz and 3.3V

1. Weld the regulator (IC1) and the other capacitor (Cin,Cout, C-NRF, etc)
2. short-circuit the 3.3v jumper
3. weld the C1, R1, R2 parts (voltage divider circuit)
4. use a TP4056 module and attach the LiOn battery on X1 input

5V - Arduino Pro Mini 16Mhz and 5V

1. Weld the regulator (IC1) and the other capacitor (Cin,Cout, C-NRF, etc)
2. short-circuit the 5v jumper and J2 pad
3. attach the the 5V supply on X3 input
4. the regulator gives 3.3v only to antenna

AA Battery --> 3V - Arduino Pro Mini 8Mhz and 3.3V

1. DON'T weld the regulator (IC1)
2. Weld the C-NRF capacitor
3. short-circuit the 3.3v and 5V jumper, J2 pad
4. weld the C1, R1, R2 parts (voltage divider circuit)
5. attach the 2xAA battery on X3 input
