MacArthur HAT production
#19
(2023-12-10, 01:29 AM)TVR Wrote: The Raspberry Pi Foundation has just announced the new HAT+ specification:
https://datasheets.raspberrypi.com/hat/h...cation.pdf

Section 1.1 states:
Quote:The original HAT specification is now deprecated. All new HATs should follow the HAT+ specification.

The main changes with the HAT+ specification are:
• HAT+ boards must be electrically compatible with the STANDBY power state, where the 5V power rail is powered, but the 3.3V rail is unpowered.
 NOTE Raspberry Pi 4 and Raspberry Pi 5 support the STANDBY state, while older Raspberry Pi models do not.
• The specification is less prescriptive about HAT physical dimensions.
• The HAT EEPROM content is now much simpler.
• A special class of HAT+s that can be stacked with an extra HAT+ on top is supported for a maximum stack of two HATs.

How will this affect the MacArthur HAT?

We do not use EEPROM so no problem.
