Input/output module

PCB reference RU80068.3

Estimated building time: 1,5 hours

To complete this step the PCB with reference RU80068.3 is required.

Sort all required components as indicated in the BOM:

Bend the resistors so that they fit neatly right away:

Solder the resistors on the right position.

Add also the IC sockets by soldering only 1 pin. Check the direction and alignment of the IC sockets before soldering the remaining pins.

Put the 21 pin connector to the board, do not exert any excessive force:

Solder only pin 1 and pin 21 and check for a right angle. Correct if necessary and solder all remaining pins:

Insert the electrolytic capacitors (e-caps), do not mix the 10uF and 22uF, they look exactly the same.

Solder only 1 of both legs, this allows lining up the components. Watch the polarity, correct if necessary and solder all remaining legs:

Thereafter add the trimpot for the microphone preamp:

Add the film capacitors:

Only applicable for
prototyping boards and depending on the choosen components, bend the capacitor legs as illustrated to adapt the lead spacing:

Also plug the corresponding IC's into the IC sockets, double check the direction of the notch to avoid destroyed IC's afterwards:

Finally use a pliers to press all solder pins into the PCB. The solder pins should have a diameter of 1 mm, the holes in the PCB have the same size. So firmly press the pins into the right positions:

Thoroughly clean the PCB using flux cleaner and check for bad soldering or tin bulbs:
