There are multiple sources of power on the Mayfly boards. There’s 3.3v that’s always on, then there’s a separate 3.3v regulator that can be switched on and off by setting pin D22 high or low in your code. There’s also a separate 5v boost regulator (and on Mayfly v1.x) a 12v boost regulator, both of which are also controlled by D22 in your s…[Read more]

How do I switch over to the 12 volt power supply? The Board Features Overview page says the 5 and 12 volt circuits can be accessed from pin D22, but I am having trouble finding that pin. I notice there are some pins labeled Sw3, Sw5, and Sw12 at the bottom of the 20-pin headers. Is that where I switch the supply voltage, and if so, which pins am I…[Read more]

It is working now! Thank you for helping me through that!

Thanks for the screenshot, that shows the Mayfly board is being seen by the computer, so it’s not a cable or Mayfly issue. But Windows doesn’t know how to use the Mayfly correctly as a USB device because Windows didn’t automatically install the necessary drivers. I’m assuming this is the first time you’ve connected a Mayfly v1.x board to this p…[Read more]

I have swapped out the cable for one that has transmitted data for other devices and I am getting the same thing. My board receives power, but it doesn’t talk with my computer. The attached picture is what shows up on my device manager when I plug it in.
Shannon Hicks replied to the topic FTDI and iOS devices in the forum Infrastructure and Equipment 1 years, 7 months ago
We use Android devices for any portable interfaces in the field, along with an FTDI cable attached to the 6-pin FTDI header of the Mayfly. The Mayfly v1.1 has it’s own CP2102 USB chip on board that works through the USB-C jack on the Mayfly, but Android devices can’t natively use it because they don’t recognize the CP2102. Plus with the i…[Read more]

Hi All,
I have been using android phones to connect a USB C -> FTDI cable to the FTDI port on the mayfly data logger to read data via the Serial USB Terminal app in the field.
Have any of you had success with connecting an iOS device (iPhone or iPad) to the mayfly data logger via cable?
Thank you.

If you disconnect your Mayfly board from the computer, does COM3 still show up as an active device on your computer? I’m guessing that COM3 is actually another com port on your machine, like a bluetooth or other USB device on the motherboard. If your Windows computer correctly identifies the Mayfly board, it will shows up as “Silicon Labs C…[Read more]

Apologies if this is duplicative – I searched but I couldn’t find an answer. On the MMW dashboard for a site, the data is tagged as provisional – is there a way to approve/QC data on the MMW site as a publisher of the data?
I developed an R Shiny widget to display the last 72-hrs of data and was wondering if I can limit the results to only QC’d…[Read more]

I am having trouble getting my IDE/laptop and Mayfly to talk to each other. I have installed the EnviroDIY ATmega Boards package and have the EnviroDIY Mayfly 1284p selected as my active board. For my port, the option for COM3 is listed under the serial ports, and I have it selected. I have the data logger and my laptop connected with the USB-C…[Read more]
