HAT RACK
HAT RACK is a mounting board for Raspberry Pi HATs which makes it easy to connect multiple add-on boards together. It's plug & play, DIN rail mountable and can be daisy chained without any special adaptors, ribbon cables or messy wires!
Stackable HATs have become the de facto standard in the Raspberry Pi community, but stacking HATs together can make them difficult to get to, awkward to maintain and can lead to excessive heat build-up. HAT RACK solves this by separating the stack into an easier to manage array. Each board is connected together in parallel which is perfect for I2C based HATs such as Raspberry Pi's Sense HAT.
