Hi, I want to hook up a Raspberry Pi to an Arduino. I have watched the Dronebot Workshop tutorial on it. I understand that I can hook them up OK except that My Arduino is a clone. So I don’t know if it will automatically step down from 5 volts to 3.3 volts. So I want to take the precaution of using an I2C voltage level converter, which is advised anyway incase of peripherals stepping the voltage back up to 5 volts.
The problem is that I am a rank beginner and, as Amazon don’t seem to have any suppliers, I’m a bit lost! Does Dronebot Workshop supply components or does anyone know any suppliers in the UK?

a google of level shifter will bring up a bunch of suppliers. Below is a link to one.

I get quite a few parts from a supplier in my country, which also ships to other countries:
If you are less in a hurry, you could consider buying a collection of modules and such from China (AliExpress)
It takes a few weeks to arrive but the prices are sometimes downto 1/10th of what I pay locally (for the exact same item, as they originally come from the same manufacturer)
In general, try and look if there are any semi-local electronics stores around in your country (Like the one Bill has around the corner of his house) it sometimes take a bit longer to find them on the internet, but they typically have a much larger range of items to sell and at a far better price too.
Another place to look is Banggood.com Most of their items are shipped from China too, but in some cases they ship it from the UK-Warehouses
Hope this helps,
Macoofer

Thanks folks.
I have the part on order. It's a 4 channel instead of a 2 channel version. But that may give me some versatility with the project farther down the line. Thanks again for your help.
