Step 3: Decoupling Capacitors

You will now be installing tiny 0.1μF ceramic capacitors into C6 and C7. These are simple decoupling capacitors that filter noise on the microcontroller's power lines.

Tools Needed

• Soldering iron
• Cutter

Parts Needed

• 2 x 0.1μF ceramic capacitor

Instructions

1. Seat the capacitors into the board at C6 and C7. Ceramic capacitors are not polarized, so it does not matter which way you insert them as long as they are on the correct side of the board.

   

2. Solder into place.

3. Trim the lead wires.
