Bill of Materials
This is the required bill of materials if you bought the PCBs+Panel+IC only. All components listed below are already included in the full DIY kit.
Resistors usually included in the kit are usually Multicomp MF12 Series.
Note: Use of 1% tolerance 3.5mm resistors highly recommended.
