💬 In Wall AC/DC Pcb for MySensors

[Sefi Ninio]

SMD is easier with solder paste and hot air solder

[sundberg84]

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.

Images on https://www.openhardware.io/view/13/In-Wall-ACDC-Pcb-for-MySensors has been updated.

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

[sundberg84]

@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???

[sundberg84]

@ashway - this is correct/latest version. The manufacturer rev 3 equals the latest 4.1.

[shabba]

Excuse the possibly silly question but the buy options is PCBs only? Or does it come with the housing too?

[sundberg84]

@shabba - PCB only.
I recommend using 3dhubs.com and find a local 3d printer for the case.
Files (.stl) attached in the project.

[shabba]

@sundberg84 thanks - I had a look in the design files and I think I covered the comments but could not find a .stl file.

[sundberg84]

@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

[sundberg84]

@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.

@sundberg84
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.

[sundberg84]

@johmei - sorry, I wish i had any good recommendations for local PCB service.
The only research I have done leads me to that they are VERY expensive compared to these 10x10 chinese.
Good luck with your build! Images are always appreciated! ;)

[johmei]

@sundberg84 - Thanks, but I was thinking about 3D printing services for boxes, cases and mounts in very small series (maybe even singles)?!

Regarding images we'll see if I manage to get any AC stuff going anytime soon. I have a lot of respect for AC and probably want to get to know the Arduino platform a bit more first. Got my first couple of regular DC nodes running yesterday and they have been running really well for 12 hours now (impressed of the small nrf24+ radio range). So many ideas to explore. =)
Actually ordered a set of your newbie PCBs a few days after my In wall AC PCB order so there will be a lot your autograph around my house..

[sundberg84]

@johmei - haha, I hope they will help you some in your quest for HA. About 3d printing I use 3dhubs.com and have tried different once and been satisfied. Go for one at your location if you want to pick up. I use one in Kalmar with shipping I can recommend.

[johmei]

Can't help myself but have to see if I can get a AC node going. question regarding capacitors: C1 is specified as 10uF in the circuit diagram but the BOM states 0,1, 1,0, 4,7 uF capacitors. What is the recommendation from the creator? Thanks

[sundberg84]

@johmei - you are right and the BOM is updated.
C1 should be a 10uF in my schematics, but its optional. Its recommended to have one higher and one 0.1uF capacitor with the voltage regulator since they can help avoiding spikes and drops.

[smilvert]

@sundberg84 Which housing are you using to this project? Can't find the stl-file. Does the 3dBoxWRelay.stl from the smd-project work here as well?

[sundberg84]

@smilvert - No, Im not sure.
I have not made a 3d box to the new version - let me have a look at that. Im working all weekend but i will look into it asap.
