Something for the weekend: Energenie Pi-board extension guide

6th November 2015

When it comes to getting the most out of your tech, it’s all about knowing how best to enhance its features. The majority of technology can be extended to offer you more benefits and ensure that you are using it to its fullest extent, meaning you get better value for money and don’t miss out on what else it has to offer.

This goes for the Energenie Pi-HAT, which can be extended to allow you to benefit even more from its great features.

If you have a Pi-HAT to hand, you’ll see that the first 26 pins are covered when attached; however, you can actually free-up any unused GPIO pins. This allows you to boost its functions even more.

Our handy guide will help you access the unused GPIO pins of the Raspberry Pi, as well as how to use these pins for other purposes, furthering the benefits of the products. So, gather up your equipment and get set to extended your Pi-board with these steps:

What you will need:

Hardware
– A Raspberry Pi A,A+,B,B+ or 2
– Mouse, Keyboard, HDMI, monitor
– An Energenie Pi HATs
– Pimote: https://energenie4u.co.uk/catalogue/product/ENER314
– IR Pimote: https://energenie4u.co.uk/catalogue/product/ENER314-IR
– Two way Pimote: https://energenie4u.co.uk/catalogue/product/ENER314-RT
– Male to female GPIO jumper wires (£2.99 from CPC http://cpc.farnell.com/1/1/125375-pro-signal-jw-012male-gpio-26-way-200mm-cable-male-pins.html )

Energenie Pimote:

The Energenie Pimote only requires 8 pins. Pins: 1, 2, 6, 11, 13, 15, 16, 18, 22.

Connect the jumper leads from the GPIO pins to the Energenie Pimote like so:

You will now have access to the remaining 16 pins. Users may also reassign pins. Note that the female pins on the Pi HAT cannot be changed. The trick is to use the jumper lead connectors to connect from your desire pin to the pin you wish to use. You will also need to update the reassigned pins in the GPIO pin definition in the python script here:

Energenie IR Pimote:

The IR Pimote only requires 5 pins. Pins: 1, 2, 6, 11, 12.

Connect the jumper leads from the GPIO pins to the Energenie IR Pimote like so:

You can change the IR signal input and IR signal output pins. First connect the female pin to your desired GPIO pin. Connect the male pin the the pin socket on the IR Pimote. Update the change on the LIRC module here:
modprobe lirc_rpi gpio_in_pin=18 gpio_out_pin=17

The full guide can be found here

Energenie Two way Pimote:

The Two Way Pimote requires all pins apart from: 4, 11, 16, 18.

Conclusion:

You can now get the most out of your Pi-HAT by accessing unused GPIO pins for a huge number of reasons. These pins can be used for other hardware or for extra sensors, which means that you can gain loads of benefits and access a range of features.

Find the right solution for you and your home, and don’t miss out on anything that Energenie has to offer.
