- Insert the 8-pin DIP socket into U7. This is where the EEPROM will sit.
- Find the footprint for U7.
- Seat the socket, being mindful of the notch that indicates orientation on both the footprint and socket.
- Tape the 8-pin DIP socket into place.
- Solder the socket into place. As before, make sure the socket is flat against the board. The top-right pins as pictured are all ground pins, so they will require more heat to melt. Be patient with these pins.
Solder a 10kΩ resistor into R36. This is a pull-up resistor to create a weak high on the SDA line (YOU LOST ME HERE ON THE REASONING). Press the resistor firmly into place (picture needs to be updated).
Info Remember, resistors are not polarized.
- Solder a 0.1uF capacitor into C13. This filters noise for the EEPROM power.
