I have this RTC module by MikroElektronika:

enter image description here

I need a schematic and/or user manual but it's no longer on the MikroElektronika website. (There's a similarly looking PCB but it uses a different IC than the PCF8583 used here.) Any help would be appreciated.

For a very simple board like this it should take less than an hour to make a sketch of the circuit. Even less time with the use of an ohm meter to confirm some connections.

  • \$\begingroup\$ Thanks for your answer, but why would I reverse engineer it if somebody might have all the documentation? \$\endgroup\$ Jan 31 '15 at 15:24
  • \$\begingroup\$ Also, the diode types aren't readable without desoldering \$\endgroup\$ Jan 31 '15 at 16:55
  • \$\begingroup\$ What are you trying to do? Build more of these or simply make use of the one that you have? As for documentation get a data sheet for the PCF8583 and you get 37 pages that tell you more than you need to know to use this module! \$\endgroup\$ Jan 31 '15 at 18:15
  • \$\begingroup\$ One last thing. Several of the modules at the site you linked in your question have exactly the same chip on them AND they are offering an RTC examples link. What more could you ask for? \$\endgroup\$ Jan 31 '15 at 18:22
  • \$\begingroup\$ What more could I ask for? A schematic without having to reverse engineer. Who says the other modules have the same schematic? \$\endgroup\$ Jan 31 '15 at 18:30
