39 hours	pcb: Remove note about MAC EEPROMpcb	xengineering
	It could be validated that the ESP32 S2 has an embedded hardware MAC address and it is assumed that this is the case for the S3 too.

3 days	pcb: J1: Select JTAG connector without pin 7	xengineering
	It seems that pin 7 (KEY) is always not connected and used with some cables to block wrong-oriented connections with plastic at this point. The ARM documentation [1] sadly is not very clear about this. To be mechanically compatible with all cables the cortex debug connector without pin 7 is selected by this commit.

4 days	pcb: Do not populate J3 WAGO connector	xengineering
	This is currently the only THT part. It can be soldered easily by hand so it is for now excluded to make production cheaper.
4 days	pcb: Add J3 WAGO connector from Ultra Librarian	xengineering
	The actual files are not committed because of licensing concerns. Will be replaced soon by self-developed symbol and footprint.
