PCB Boards for MySensors

[smokey1300]

Thanks for the reply Cory. I like the design only thing is I have a hard time soldering SMT components. I might order them and tough it out anyways. I appreciate the documentation as it helps a lot. Do you have the schematic too?

[Cory]

I did the design in Eagle after watching some youtube videos. OSHPark has a design rules file and can accept the eagle file type without exporting.

This board was my very first (second rev to fix some issues). Here is a link to the files if you want to modify it.

Personally I think it would be better to start from scratch in order to get the learning.

My goal was to get the board as small as possible (to reduce cost). I have a smaller one with the radio inside the arduino footprint, but I haven't tested it or shared it yet.

@Cory Great I'll check it out. Do you power any with 3v battery? If so how long does it last? Thanks again.

[jemish]

any PCB available for fan control using dimmer with rotarry switch?

I just know only circuit diagram. but I don't try that.

@Cory What size SMD components are used for the caps and resistors?

Just ordered 9 boards to test with and ordered a lot of SMD components but then realised they do them in different sizes, SMD is very new to me. Most of what i've ordered are 603.

Great looking boards from OSH Park, seem great quality.

Below you will find a link to a board I made and now use with the MySensors library and EasyIOT.

This is a version with the small nRF24L01+. I'm now working on a version using the longer board version (with SMA antenna).

[GertSanders]

@GertSanders I've now used three of these boards with Domoticz (running on a Synology NAS). Next test is running Domoticz on Raspberry Pi 2 with these sensors.

@GertSanders
Nice design! :+1:

I think I will purchase this one instead of my design next time I need some mysensor nodes...

[TD22057]

FYI for anyone looking to get PCB's made, here is a price comparison site that shows you various manufacturers and what they'll charge you for different sized boards. Prices are crazy cheap these days...

@hek Since the OP has not been online the past 5 months, is it possible for someone else to take over editing this post of PCB's for MySensors ? I think you were making a site to collect open source hardware, is that a possible avenue to publish design compatible with MySensors ?

[hek]

Yes, the idea was to have a openhardware.io as a place for publishing open hardware accompanying the mysensors site/forum.

The emryo is still on my computer but I got stuck trying to visualize gerbers in 3d and doing SSO integration with the mysensors forum. Then some other projects came in the way... and summer.

I've picked up the gerber viewer ideas again last week.. This time I will probably do it as a NodeBB forum plugin to get integration more seamless with the community. Where you can drop gerber files directly in post or link them from your github repository.
I would also need some new mechanism and/or layout to make the open hardware- and sensor projects easier to find here on the forum.

Would've been nice to do a couple of weeks fulltime on this project to get there quickly.. But still have to take care of my dayjob :sweat:

Meanwhile I suggest you post your project in a separate thread and reply here with a link until I sort things out in my mind and plugins. :)

[Anticimex]

Feel free to add my board as well:

[GertSanders]

Visualising 3d gerbers is available on other sites. Why repeat the effort ? Access to the gerbers or board files would be sufficient, if accompanied by some explanation or wiki about what you can do with the provided files.

As a designer I do not mind making some documentation, but storing it in an accessible location would be nice.

Github comes to mind. Links to github and recommendations on a minimum set of documents (and "proven" compatibility with the MySensor library) would be totally acceptable for me, but I would like some guidelines.

[GertSanders]

Here is my version of a compact board for inclusion in the list. This board is equipped with two connectors for NRF24 (so you can choose the orientation of the radio) and uses the MySensors libs. Works in five rooms in my house now.

Eagle files are added:
selfcontained low power node v1.sch
selfcontained low power node v1.brd
BOM:
selfcontained-low-power-node-v1.csv
Schematic in PDF format:
selfcontained low power node v1.pdf
A panelised version (could be cleaner but works):

My version of Optiboot for this board assumes the flashing LED is connected to pin 8 (as is on my board):

optiboot_atmega328_8Mhz_B0.hex

And here are my settings for the board.txt file:

###############
possible upload speeds: 9600, 14400, 19200, 28800, 38400, 57600, or 115200
for 8MHz we keep this slower to avoid transmission errors.
First settings are for use without a crystal, internal oscillator at 8MHz and Brown Out Detection switched off (to save batteries even more).
Second settings are for use with an external 8MHz crystal (better stability of frequency) and Brown Out Detection switched off (to save batteries even more).

My IDE is the Arduino IDE 1.6.5

Under the "hardware" directory I keep the following structure (now zipped): atmega328p.zip

Original files are available on GITHUB: https://github.com/GertSanders/batterybasedsensorv2

[GertSanders]

Here is an AC capable board (in a first tested version, although the filename says V3), it's my first actual spin of the PCB:

AC based repeater V3.sch
AC based repeater V3.brd
AC based repeater V3 partlist.txt
AC based repeater V3.pdf

For some images, look here:
http://forum.mysensors.org/topic/2374/50mm-x-50mm-board-with-different-powering-options

I had the boards made by DirtyPcb, a link to order some if you want to test this boards is here:

I use the atmega328 with the same boot loader as my red board.

Any improvements or suggestions are welcome.

It allows use of 2 AAA batteries, or 5VDC on the VCC input, or anything between 6V and 24V DC when using the step down DC DC converter or 220V AC when using the HLK-PM01.

There is a place for a 3V3 regulator (when using 5V on the Vcc circuit).

There are jumpers to swap the signal (SDA or SCL) on 2 pins, and there are jumpers to enable I2C pull up resistors if needed.

@meanpenugin will you maintain the topic post as new boards pop up in the thread? It's really nice with a list. If possible and @hek approves, perhaps you also could add a MYSX compliancy line with revision (1. 0 to 1.5 and sometime even higher). That way a MYSX daugherboard developer can get an overview of compliancy. I would also be great if any additional notes on MYSX daugherboard size constraints could be somehow made visible, but that would be the responsibility of the "motherboard" designer to clarify.

[GertSanders]

Seems like meanpenugin has not logged on for at least 7 months ...

[Anticimex]

I also noticed. I think I'll flex my moderator muscles and take over the topic to keep it up2date. And relinquish my powers back to Mr penguin, should he resurface.

[GertSanders]

Things I would keep per board:
Titel
Short description
KiCad or Eagle files
render of the PCB itself via Mayhew Labs or other Gerber viewer)
BOM in plain text form (if provided)
Boot loader used (or I just add a TXT with the name or URL of the boot loader)
TXT with what needs to be added to BOARD.TXT if Arduino IDE is used
MYSConnector version if provided
powered by BATT (y/n)
powered by 5V (y/n)
powered by DC 6v or above (y/n)
powered by 110/220V AC (y/n)
through hole components only (y/n)
SMD components used (y/n)
images of a build proces
images of completed builds

I tried to get all that on GITHUB, but my understanding of this platform fell short, so now I keep all this in Dropbox (to share between my various platforms)

A specific MySensors site (as Henrik mentioned) would be nice.

[sundberg84]

Hi - yea this would be nice with a own perhaps Wiki to add and remove hardware components :)
