100pcs TTP223 Touch Switch Module Capacitive Sensor Switch DIY for Arduino Raspberry Pi

Documentation isn’t there, and you’ll need to fine tune the capacitor if you attach a wire to it for extended range or a larger touch plate.

As hobby as I feel we have all had the situation of making a purchase receiving the item and realizing we were getting a supar product. This was not the experience I have with the seller or items full sthe product arrivexactly on time and a is a simple package. The boards were still connected in 10 columns and 5 rows on 2 snap apart boards. Each individual board was checked for capacitors and resistors, Using a multimeter on each and testing 5 separate I can say without reservation that everything is perfect and exactly as advertised. Whether looking to experiment, hobby, Or if you're wanting to build that large touch reactive LED table we've all been seen on YouTube lately, this is definitely the seller to go with. While I'm not always thrilled about modules and components I order and receive this one is definitely fand I was pleasantly surprised at the quality they were received in. There are a ton of videos on YouTube for applications, Usage,As well as modifications.

The images in the product page are incorrect. I bought these thinking that it would be easy to add an external capacitor to adjust the sensitivity. Unfortunately, the contact points for an external capacitor are much smaller than depicted in the images. This makes it nearly impossible to add a capacitor.

You get enough little boards to last you a lifetime of DIY projects. They pretty much break you off a section of the panel, which is preferable to having a 100 boards loose in the bag. They work exactly as expected.

works as expected.
