BOM & Schematic for Unicorn pHat?

I have a Unicorn pHat with a missing SMD component. I believe the missing component is a resistor, but I do not know the value.

I have supply of SMD components and can solder a new one in (can do SMD component replacement) but I would need to know the replacement part. Can the schematic, BOM and other design files be shared?

The missing SMD is directly to the left of the Pin1 GPIO pin, between the component marked ‘331’ and the upper-right LED.

See photo. Thanks for the support!

OK! I replaced the missing SMD component with a .1uF capacitor, and the Unicorn pHat works perfect now.
