I just received my Macarthur HAT a few days ago, with the power module.
With everything assembled the Daisy Hat does not fit flush with the power module installed.

Other than removing the power module (which kind of defeats the purpose of putting a pi on a boat)

Is there a work around for installing a Daisy hat?

Thank you in advance

Oops! I had to check myself how Sailoog did it.

He documented the procedure as the 4th floor on page 7 of the manual for the MacArthur HAT:
Quote:If we want to connect another HAT, we must
use an extra GPIO header extender of normal
size and 4 spacers of 20mm and M2.5. Finally,
we will secure the dAISy HAT with 4 M2.5
screws.

He was likely using this kind of GPIO header:

On a quick search, I found the above in this set on Amazon US:
https://www.amazon.com/Geekworm-Stacking...B0827THC7R

In hindsight, we should have thought of offering a kit with those parts as an option, to safe everyone the time to source them separately. We will look into this.
Thank you Adrian, this helps alot
Ops, yes, we should provide a kit header/standoffs/screws for these cases.

We found a supplier for the stacking header, but are still waiting for them to arrive.

Besides the Amazon kit linked above, the header is also available from Adafruit (US), Pimoroni (UK), The PiHut (UK), Small Devices (AU):
https://www.adafruit.com/product/4079 (currently out of stock)
https://shop.pimoroni.com/products/boost...7414520906
https://thepihut.com/products/gpio-riser...spberry-pi
https://smalldevices.com.au/products/booster-header

You may find them at other Raspberry Pi supplier when searching for the terms "riser" or "booster" header.
Good news: Starting today, the parts required for 4th floor stacking are now included in the standard MacArthur kit.

The 4th floor kit is still available as a separate purchase in the OpenMarine and Wegmatt web stores, in case you bought the MacArthur HAT before this change.
