Did some more edits on the PCB, including adding an additional I2C breakout header, I chose the Breakout garden pin order for this header.

• Female header would enable users to plug in either some straight or 90degree pins
• Alternately plug in a breakout garden socket
• Enables plugging in the I2C range of Breakout Garden components
• Also enables use of 4trionics ultrasonic sensor
• Alternately you could stick some Dupont cables into it if that's more your jam
