Are you saying you’ve got a bad cable or a bad Mayfly?  Have you tried a different USB-C cable?  The pins in USB-C connectors and cables are extremely small and are easy to fail.  And when the pins in a cable’s connector get bent or damaged, we’ve seen them inflict damage on brand-new boards, so I’d suggest trying a new cable or two.

Matt, you are correct that it appears the solar panel was connected to the spare LipoBatt JST socket on the Mayfly, which causes the board to see those high levels during the day.  The voltage regulator on the Mayfly can theoretically be damaged if you put more than 6.5v into the board via the LipoBatt jack, so they should definitely fix that as…[Read more]

@aufdenkampe, do you have any information about why certain sites are having this issue of their map marker being gray even though they’re still sending live data, or the issue of sensors not being able to be deleted from sites?

The dipswitches are mainly there to let people know their board is working during initial testing or desktop deployments.  Anytime a board is deployed in the field as a “sleeping” station, power savings are important during the sleep period.  So I put the dipswitches on the new versions of the Mayfly to allow people to deactivated the LEDs.  Th…[Read more]

Powering the Mayfly v1.0 and v1.1 from the solar jack only would not be recommended because the power input circuit was not designed to operate that way.  The most electrically efficient way is to use the 12v-to-5v converter and connect it to the USB-C jack and then deactivate the USB interface circuitry with the dip switch as explained above.  T…[Read more]

That’s great, I’m glad it worked.  Based on your screenshot, I can tell that your station is running a sketch that I programmed onto that Mayfly board in March of 2018.  It’ll still work if you’re using the same CTD and turbidity sensor it originally had on it, and it will save data to the memory card every 5 minutes.  It had the ability to tr…[Read more]

As stated on the Details and Spec page, the Mayfly v1.1 can only source about 100mA from the 12v output, so if your motor draws 400mA, you’ll need to power the motor directly from your 12v source and not from the Mayfly.

That is correct, the Mayfly v1.0 and 1.1 boards do not have a separate external power input for 4v to 12v sources like the v0.5b boards.  This is because the main voltage regulator on the v0.5b board that accepted that wide range of voltage was discontinued by the manufacturer, and the new voltage regulator doesn’t accept that high of an input…[Read more]

The Adafruit CP2104 Friend has the correct 6-pin layout to work perfectly with the FTDI interface header on all Mayfly versions.  The attached photo shows one connected to a Mayfly 1.0 but you can connect it to the Mayfly v0.5b the exact same way. Give that a try and see if you’re able to communicate with the Mayfly board.  If not, it’s possible t…[Read more]

This looks like a common database issue that usually gets resolved by a server restart, so maybe @aufdenkampe can comment on it?

I assume you mean the manual is pointing you to Github where you attempted to download the libraries?  If you go to https://github.com/EnviroDIY/Libraries and follow the instructions on that page in the section called “Installing Libraries in Arduino IDE”, you’ll save the libraries.zip file by right-clicking on the link in the text that says…[Read more]

You should try adding it as an issue (if it’s not already reported) on the ODM2DataSharingPortal Github issues page so the development team that’s working on TSV will see it.

There’s a few things in your post to clarify to make sure we’re talking about the same equipment.  The various instructional videos and manuals we’ve released in the past few years cover several different configurations of sensors and cables and equipment.  The majority of the stations we deployed before 2020 had a Meter Group CTD sensor and a C…[Read more]

The only difference between versions is stated in the first paragraph of the blog post:  the only major change being the circuit that provides the switchable 12 volt boost output was redesigned to provide a higher power output. And 2 minor changes: one set of pin labels were slightly change and one solder jumper was added to the back of the board…[Read more]
