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? Schematic of NRF51822

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?

  • \$\begingroup\$ We would all have to follow three links just to understand what you are asking. Can you inline the relevant images or specifications and ask specific questions on parts you don't understand? \$\endgroup\$ – Transistor Jul 28 at 9:41
  • \$\begingroup\$ Sure, I will include the schematic. I do not understand what the names stand for (e.g. DCC, VDD, P0.30). \$\endgroup\$ – JavaForAndroid Jul 28 at 9:43
  • \$\begingroup\$ That's fine. Make that clear in your question. \$\endgroup\$ – Transistor Jul 28 at 9:44

    \$\begingroup\$ You've linked to a catalog page for the device. You need to identify the chip on the board and get the datasheet for that. \$\endgroup\$ – Transistor Jul 28 at 12:22

    \$\begingroup\$ Do not connect this to a lipo battery, as explained at your previous question a coin cell is enough. If you did any actual research you would find that could run it at a heavier usage than yours for years. \$\endgroup\$ – Chris Stratton Jul 28 at 12:45
