Raspberry Pi Pico using Earlephihower Arduino Ide board manager to control a servo using servo.h 

Hi Paul it’s very hard to recommend a certain brand. I buy them from eBay if I need them quickly I use a Uk based seller. This does mean if there was an issue with them I can get a refund. Some seller I have seen with a 6 year warranty but I tend to go for cheap ones. It’s hard because they can easily be rebranded by the seller so you don’t have a clue who really manufactured them in the first place. The ones seen in the demo are Tower pro sg90 on my layout I have some which had no name on them. I have also used some other supplier. So sorry this is the best answer I could give as I have never had an issue with any of the ones I have purchased so far. John
