These work great! I haven’t had any issues with them whatever and they do exactly what they are supposed to do. I’m an avid Arduino (or clone) hobbyist. I love the form factor of these little ESP8266 boards. Just big enough to be able to work with them easy enough, but tiny enough to fit in even the tiniest project boxes (ok well almost; still pretty cool!)

Nice servo for building your own 3d printer bed level probe. It fit perfectly in the print found on instructables. I did have one go out on me and needed replaced, but that may have been from my experiments while building the probe and having the servo run past the hard stops on the probe. But you get 5 so there is room for error 🙂

I added one of these to my FL son Q5 Delta printer to replace the noisy extruder driver that it came with. This worked great. I had to make a change in the Marlin firmware to reverse the direction of the stepper motor but everything worked out great in the end. the heat sinks are pretty beefy and should keep everything cool in the long term and the drivers are 2208 silent steppers…and they live up to their name.

Boy are these things useful. Takes any DC voltage from 4.5 to 53 volts and drops it to any voltage from 3v up as long as the output voltage is 1.5 volts less than the input. They are switchers so they’re about 95% efficient so going from 48 volt power over ethernet down to 5 volts doesn’t burn up a lot of energy unlike old-fashioned analog regulators. I use them to run 12 volt fans at 9 volts to make the fans run really quietly while still moving a decent amount of air.

These fans aren’t the biggest or the quietest around (in fact, after a couple of days they got louder) but they do the job.

Easy to install and help keep the Rpi cool…. what more could you ask for?

This camera has night vision and is a plug n plat for arduino and raspberry pi. It would have been ideal if it cane with a case but there are builds for you to print on a 3d printer. For best performance and not too much strain adjust to 720p and get 60 fps. The raspberry pi 4 recognizes it as a camera no additional programming is required. Delivery was fast and there are tutorials on being able to incorporate this into home assistant.
