PCB Boards for MySensors

[hek]

I'm working on a new site to keep track of open hardware projects. Will contain things like versions handling, fork a project function, BOM and hopefully a online viewer for the gerber the files.

Nothing online for quite some time but the url will be: http://openhardware.io
.

@hek Nice. I like it.

[Nicola Reina]

Looks pro. Are you planning to abandon the original community?
Would be a pity :-(

[hek]

Abandom? No way. This is a complement to MySensors for keeping track of open hardware projects.

[RJ_Make]

Really looking forward to this site. Anything we can do to help it along (for those who don't really program), maybe a little financial help??

[hek]

It's progressing.. Social login finalized and design of most parts. Hope to get some more time during x-mas vaccation to get gerber to svg functionality in place together with github integration...

I would like to have some kind of "donate-to-hardware-creator" functionality... anyone here who knows paypal apis and in-and-out? (maybe i'll just contact them directly for the options available).

Not keen on soldering SMD, I designed my own PCB.

The PCB has a flexible design (use jumpers):

• use with battery
• use with 5 volt (and LE33 for NRF24L01+)
• use with voltage stabilazitaion to 3.3V (LE33) for ATMEGA328P and NRF24l01+

OSH Park Link

I am programming it with an ISP.

Use a 8 MHz setup: select Lilypad/328p in the Arduino IDE and first burn the bootloader.

Then I set fuses with mit usbtinyisp to not reset the eeprom with the upload of a sketch (no new node id)

./avrdude -C /Applications/Arduino.app/Contents/Java/hardware/tools/avr/etc/avrdude.conf -c usbtiny -p m328p -U hfuse:w:0xD2:m

an enable low voltage usage with battery:

./avrdude -C /Applications/Arduino.app/Contents/Java/hardware/tools/avr/etc/avrdude.conf -c usbtiny -p m328p -U efuse:w:0x07:m

@meanpenugin first post probably needs a slight update on available boards :) And ongoing projects..

[stevenwatson011]

Are thses PCB board available as stock board?

[tbowmo]

@stevenwatson011

Only the sensebender is available as official board (described in the thread "Minimal design thoughts")

Some of the other boards are supplied with manufacturing details, so you can order your own pcb's and populate the boards yourself.

May you want to add my Boards?

I am trying to find a new sensor board design and I came across this one on OSH Park. Only thing is I don't who's board design or what documentation goes with it. Anyone have any ideas which one it is? Could it be Mean Penguin version?

@smokey1300
This is a board that I designed. I didnt think anyone would actually stumble on it. :-)
I'm not sure about any mean penguins, but here is some extra documentation.
https://docs.google.com/document/d/1WtImjSbQPctq8rUAT6k1CyUgJHuo2WDs6bO2HfEr8NI/edit?usp=sharing

Let me know if you want more info. I have built 3 sensors with these boards with no issues.

[TD22057]

@Cory Thanks for the docs - I was looking at your board as well because it's the closest thing to what I think I need and the extra docs help a lot. What software did you use to do the design? I'm thinking about using your design as a baseline with some small changes like:

• slightly larger board with corner holes for easier mounting
• support for the ATSHA204 message signing chip

I've never done a PCB design before but it looks like a fun project...

[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.

[smokey1300]

@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.

[chickey]

@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).
