jonbuford 178fc0a37b Raspberry Pi HAT Template 
This is a template for the Raspberry Pi HAT including EEPROM and
backpowering protection components per the Raspberry Pi Foundation spec
at https://github.com/raspberrypi/hats/blob/master/designguide.md

This has everything needed to create a fully compliant HAT module
design.

HAT spec indicates to NEVER\npower the 3.3V pins on the Raspberry Pi \nfrom the HAT header. Only connect the 3.3V\npower from the Pi if the HAT does not have\n3.3V on board.\n\nIF you are designing a board that could\neither be powered by the Pi or from the HAT\nthe jumpers here can be used.\n\nIn most cases, either design the HAT \nto provide the 5V to the Pi and use the\nprotection circuit above OR power the\nHAT from the Pi and directly connect\nthe P3V3 and P5V to the P3V3_HAT and P5V_HAT\npins.
Text Notes 1200 5200 0 60 ~ 0
The HAT spec requires this EEPROM with system information\nto be in place in order to be called a HAT. It should be set up as write\nprotected (WP pin held high), so it may be desirable to either put a \njumper as shown to enable writing, or to hook up a spare IO pin to do so.
Text Notes 1100 7250 0 60 ~ 0
These are just pullup resistors for the I2C bus on the EEPROM.\nThe resistor values are per the HAT spec.
Text Notes 850 1250 0 100 ~ 0
This is based on the official Raspberry Pi spec to be able to call an extension board a HAT.\nhttps://github.com/raspberrypi/hats/blob/master/designguide.md
