I would like to use a BLE module, where I can solder a tactile switch. There should be also the option to charge the module via USB. Earlier I have only worked with breakout boards, where I could connect the battery to the GND and VCC pin. Now I would like to use the BLE module directly to reduce the size of the device.
I have worked with the NRF51822 before which should meet my requirements. Unfortunately I am really new to schematics and struggling with the information provided by it. I also wondered about the naming of the pins. Is there a convention and official list where I can find more information? Could you explain me how I can find out what the different notation stands for? Is there a general legend?
The schematic of the board for the 51822 is listed here. Do you have any good literature for the wording and understanding of these schemes? Can I simply connect the battery to VDD and DCC? Doing a Google search for "VDD" is not that helpful.
I would use it with a Lipo charger like this. Would you recommend such a charger or what is the most elegant way?
