This is because ICs are usually better at sinking current rather then sourcing.

Tools Needed

• Soldering iron
• Cutter

Parts Needed

• 4 x 3kΩ resistors

Instructions

1. Find the resistor footprints on the board. R1, R2, R19, and R20 are grouped together next to the Propeller socket.
   
2. Install the resistors into their footprints.
   
3. Solder them into place.
