Hello,My apologies if this has been answered – a search didn’t turn anything up.
Are layout files (or gerbers) posted somewhere for the MayFly? I need to make a shield for a project we’re doing and am having trouble finding the correct footprint. I unfortunately don’t have a MayFly on hand at the moment to measure it myself.
Thanks!

No, the gerbers are not available.

2019-01-24 at 3:36 PM #12735Is there a dimensioned drawing or anything for the shield footprint? I understand that the goal is to prevent counterfeiting, but this doesn’t make it so easy to integrate the MayFly into oneIs there a dimensioned drawing or anything for the shield footprint? I understand that the goal is to prevent counterfeiting, but this doesn’t make it so easy to integrate the MayFly into one’s system.

I just posted the Eagle files for the protoshield: https://github.com/EnviroDIY/EnviroDIY_Mayfly_Logger/tree/master/hardware/protoshieldIs that sufficient for what you need for making your own shield?
Edit: I also added the Eagle files for the basic outline of the full Mayfly board showing the headers and the mounting screw locations.

That’s perfect, thanks! I appreciate it.

I would appreciate your insight as to what I’m doing wrong.

I use KiCad, so I can’t help unfortunately – but here’s an image with some of the dimensions. If you need any others I can add them. The pin headers are 0.1″ spacing.

My error was indeed in how I downloaded the files. Shannon, thank you for setting me straight. Daniel, thank you for the image.

2019-02-19 at 12:27 PM #12807Yes! The Mafly logger is now fully open source hardware!
We also packaged things up nicely, including additional documentation from @shicks, into official releases, https://github.com/EnviroDIY/Envir

That is fantastic news! It will speed up my preparations for the coming field season. Thanks for all your work!

I have been thinking about order some Mayfly boards through some PCB assembly service (because the board is not available in Sweden where I live).Does anyone have any suggestions or hints how to do it with the Mayfly board?
I saw somewhere that Shannon Hicks soldered some parts of the board herself. I guess I can try to order the board and see which parts might be a problem but any help is appreciated!

@Erik_G just an FYI, its made to look easy by Shannon, however it takes a lot of experience to get it right and then make it available as purchase.Typically to do an order with a PCB assembly service, the qty of 50 is when there is the lowest cost per device. However assembly services only assemble to the instructions you provide. If you provide inadequate instructions, or they get it wrong. you still pay the full cost of assembly. Then there is also testing and configuration of the board, which is probably what you are hearing.
Unfortunately with the current world situation, I imagine its getting more difficult to export items from the US, as anything shipped out the country would require it to be certified as to where its going. However perhaps you can a packet of 5 or (multiples) from the enviroDIY shop, and do a swedish user group!

2022-03-02 at 1:47 AM #16653Yes, that is true. We could maybe use 50 cards but I probably won’t make it right the first time and then I have 50 cards to recycle.
I used the board file to make some shields but this is somethin
Yes, that is true. We could maybe use 50 cards but I probably won’t make it right the first time and then I have 50 cards to recycle.I used the board file to make some shields but this is something another level. I will have a look around at the University for some expertise in the matter.
Maybe it is simpler for us to use something like a feather board and build from that. But the Mayfly is very convenient for our needs. I have used the Sodaq Mbili as well but had more trouble with that and I’m missing the stackable pin headers.
To bad it is so difficult to order boards from the US. I ordered one of the 0.4 boards years ago and it has been very handy.
Thanks for your input @neilh !

2022-03-03 at 5:32 PM #16663Erik any board that has a SAMD21 with a uSD/flashDrive and external RTC DS3231 https://www.adafruit.com/?q=DS3231&sort=BestMatch is probably a good target for using with ModularSensors. httpErik any board that has a SAMD21 with a uSD/flashDrive and external RTC DS3231 https://www.adafruit.com/?q=DS3231&sort=BestMatch is probably a good target for using with ModularSensors. https://shop.sodaq.com/search/SAMD21/ and look for LTE cellular or other cell to match your local network. LoRa seems unlikely to work with MMW but could possibly with Arduino IoT
Also there are options at https://search.arduino.cc/search?tab=&q=SAMD21
The mega2560 and Mayfly mega1284 are 8bit versions, and excellent for low power, but short on ram, flash and peripherals
