The HAT RACK 90 is a special variant of our HAT RACK board which rotates the GPIO pinout 90 degrees. This solves the problem with connectors or wires fouling on some Raspberry Pi add-on boards. Its reversible design can rotate a single HAT 90 degrees anti-clockwise or clockwise with the connectors installed on side A or side B respectively.
The right-angle headers and sockets allow multiple boards to be daisy chained together to create an array of connected HATs. BCM pin numbering on both sides allows for easy identification and it can be mounted to a DIN rail using standard DIN rail adapters.
- Reversible board can rotate left or right
- Plug & play Raspberry Pi or Pi Zero
- Daisy chain multiple boards
- DIN rail mountable
- BCM pin numbering
- Gold flash plated connectors
The HAT RACK 90 is fully compatible with all 40-way Raspberry Pi models and clones.

Connecting multiple HATs from different manufacturers can introduce pin conflicts which prevent your boards from working correctly. This usually only happens with HATs which are not designed to stack.
