1. You will need cables to connect the transmitter to the Raspberry Pi. Any cable will do obviously, but I found these quite helpful. <br/>[Order](https://www.ebay.com/itm/40Pin-Multicolored-Dupont-Wire-Kits-Breadboard-Female-Jumper-Ribbon-Cable/113310899442)

Once you have all the hardware handy, it's now time to swap the oscillator, which requires a bit of soldering. Reason for this is that the emitter you bought uses a common 433.93 MHz frequency, Somfy however requires a 433.__42__ MHz frequency. Take the following steps to exchange the oscillator
1. Identify the oscillator. It looks like this (marked with a red circle): <br/>![Front view](documentation/RF%20Transmitter%20front.jpg). <br/>Turn the RF Transmitter around. You will see that the oscillator is soldered in on 3 points <br/>![Back View](documentation/RF%20Transmitter%20back.jpg).
1. While pulling the oscillator from the front, heat up the 3 soldering point on the back with the soldering iron until the oscillator is detached from the board.

1. Clean up the remaining solder mess on bith desoldering braid or a desoldering pump
1. Now put in the new oscillator (make sure all 3 pins connect through the print) and solder it in again.

1. Solder an antenna to the ANT pad. The ideal is a 17 cm solid core wire but almost anything will do the job

And you are done!
And you are done on the mods!

Now the last step is to connect your adjusted RF transmitter to your Raspberry Pi. Use the following diagram to help you connect it
