@Ozal I had similar board which **pcbbasket made it for me, the cost was a bit higher, but they made exactly as I wanted. So I recommend them www.pcbbasket.com **

@JohanH - thanks for your reply! I also hope and think people who build commercial products have knowledge of this But as a hobbyist, there are two ways to go - either you dont have to care or go bare minimum, if something happens its your own fault, or you can try to make is as safe as possible. My idea was never to make this thread a information source for a commercial product. I wanted to try to make my own products as safe as possible since I have children around. With that in mind, i want to be on the safe side of things so some things i use from here might be exaggerated. But my PCB (HLK-PM01 breakout) is working great, and I feel safe. I have had it outdoors (under roof covered in IP5* box, -20 to +30 aprox) and its been working for me for a couple of years now. Better than I had before, when i just stripped an old fake samsung charger. /Andreas

@gohan said in Arduino Pro Mini Shield for RFM69(H)W: If I remeber right that pin is used as input so the RFM69 is not receiving any 5v signal. In addition there are people claming they have the RFM69 module working on 5v on data pins and 3.3v on vcc, but I hardly suggest to do it. thank you just what i thought . about direct 5v on data...well... i seen a big red sign saying n :DONT do it! lol Level converters are so cheap...that i ordered 5 or 10 thoguether with rfm69 board. sorry about hijack this topic, i though i was on general discussion

@Ddawme - Hi! I suggest you read all the links in the project for example: http://forum.mysensors.org/topic/1607/safe-in-wall-ac-to-dc-transformers https://forum.mysensors.org/topic/4175/clearance-creepage-and-other-safety-aspects-in-mysensors-pcbs

With how long max tape you test it ? I have a living room and i need control RGBW with about 16 meters.... I can use your controller ?
