💬 In Wall AC/DC Pcb for MySensors

@Sefi-Ninio - Yea I should. Im working on Rev 4 and there is more creepage both between primary (220) and secondary (5) and also internally in primary. Everything is ordered but nothing recieved yet, but let me give you a small peak:
-
Looking good!
I see you went with the SMD path! did it allow for a smaller PCB?
Don't see how you handle the creepage though. -
Yes - smaller PCB.
Creepage is handled with:- Greater distance between components.
- Holes in PCB between components/parts that are close to each other.
Creepage distance is calculated here: http://creepage.com/
-
Even though it's untested, would you mind publishing the Gerber and bom files?

Very nice board !

SMD is easier with solder paste and hot air solder

This PCB has been updated to Rev 4.1 with the following changes:
(Note that this thread contains the non SMD version)- Complete redesign of traces to improve size and stability.
- Nrf24l01+ now on the bottom side to make more room (with hope not RF disturbace from HLK or AC traces).
- Added silkmask with AC-DC seperation (Rev 4.1 > 5mm)
- AC clearance 2.5mm minimum
- Changed one AC trace from botton to top to increace creepage and changed milling
- MysX 2.3 + Analog IO
- Safety recommendations: This PCB meets the criteria of pollution level II (2,5mm (Basic) AC seperation and 5mm (Reinforced) AC-DC sepertion) and can be used "where only non-conductive contamination occurs. However, occasional temporary conductivity must be expected as a result of moisture condensation." Always use a sealed case to avoid contamination. Always read disclaimer.txt before using this PCB.

Please wait for PCB house to update to new gerber files before ordering (It should say M.Rev 2 (Manufacturer rev 2) for latest revision when selecting PCB house)
Im currently testing this rev...
If you want to be 100% sure, download and prev. revision. -
Hi,
Can someone please suggest replacement parts for the 110v variant of this board.
Thanks
Karthik@carthique - You need a 110 v varistor maybe something like: http://www.ebay.com/itm/321024816822?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT&rmvSB=true. Fuses and other components is the same.

@sundberg84, when I go to the order form, the revision there is M.Rev3. Which version of PCB does that manufacturer revision correspond to - 3.1 or 4.1???
@ashway - this is correct/latest version. The manufacturer rev 3 equals the latest 4.1.
-
Excuse the possibly silly question but the buy options is PCBs only? Or does it come with the housing too?
@shabba - PCB only.
I recommend using 3dhubs.com and find a local 3d printer for the case.
Files (.stl) attached in the project. -
@sundberg84 thanks - I had a look in the design files and I think I covered the comments but could not find a .stl file.
@shabba - sorry you are right.
If i remember right I removed it because I wasnt 100% sure it would be ok going from 4.0 to 4.1 on the pcb.
Let me have a look and post it asap. -

Hi sundberg84,
I bought 10 of these PCBs. So can I use this PCB, add a relay and fuse and use it inside the wall to control light switches? or should I go rather go for the other PCB "In Wall AC/DC Pcb (with Relay) for MySensors (SMD)" ?Thanks
Bob@bmokena - if it fits, that should be ok. This PCB is made a more generic pcb so you can add any sensor/accuator to it including a relay. Use the MysX i/o and you can controll your relay through D3 for example.

Hi, do you have any local Swedish printing services to recommend?Ps. Got the PCBs from Pcbway yesterday and man was I surprised how small they were. Looks great and hope to get some nodes up and running soon, once all components get here.
