Les Pounder takes a look at a new board that offers a budget introduction to home automation. Now all he needs to do is train his robot to make coffee.
A home monitoring and automation board for £12? Surely that’s not possible? Well gang, it’s time to readjust your levels of expectation…
The team from Pimoroni has released another of its Raspberry Pi Zero W sized “pHAT” boards. The Automation pHAT is a tiny board, designed for the Pi Zero, but compatible with all 40-pin GPIO Pi. It features plenty of solutions for working with higher voltage devices, and comes with a line of screw terminals to ensure a solid connection. Note that the board does require some soldering, but it’s nothing too challenging.
Looking along the board the first thing we can see is an NEC EE2-5NU relay rated for up to 24V at 2A, but according to the datasheet this relay can switch up to 220V. Yet because of the small tracks on the board and no separation, this isn’t a safe option, so you should stick to 24V maximum.
