Hardware discrepencies

On the BoM, Male USB connectors are listed, it should read Female USB connectors and if people are going to follow the build the USB connectors need to be 4 Pin and they will need a total of 8, with 4 of them being 90 degrees for the buttons and 4 of them being 180 degrees for the Pi hat.

Getting into the specifics of the resistors, adding 1/2 W as prescribed in your EasyEDA project helps.
- 4 x resistor 100Ω 1/2 Watt
- 4 x resistor 10KΩ 1/2 Watt
- 4 x resistor 470Ω 1/2 Watt

The transistor model is 2N3904
- 4 x transistor npn (BJT) 2N3904

What remains unclear is the accuracy of the Pi hat. Looking closely at the photographed example, it appears that the Pi hat is different than the Pi hat designed in the gerber files. The 4 pin header is the obvious deviation.

For the Pi Hat, the placement of the resistors is also unclear (I noticed another person commented on this as well). Since there are no 470 Ohm resistors in the photograph example, it will take some testing to determine if they are needed and whether they belong in R1-R4 or R9-R12..
