Is there a way to purchase the accessory boards for the Mayfly that you show on your website, such as the prototyping shield? Didn’t see it on Amazon.

Which ones are you interested in? I was hoping to get some feedback from other users on what type of prototype shields they might like or what features and pin breakouts they might like to see.

Thanks for the reply. In general, I would find something that broke out the analog and digital I/O pins on the headers to screw terminal blocks to be very useful and probably the most flexible. The main thing is to get something with a better mechanical connection for analog inputs than simply inserting the end of a wire into a female header. A reasonably hefty screw terminal block would probably do. Locking connectors like Grove or Molex are also good, but for analog inputs, often it’s one signal per sensor, so you wouldn’t want to have multiple inputs bundled on a single connector. The particular sensors that I’m using (moisture sensors) have 3 wires per sensor: power, ground, and signal.

I’ve seen on Amazon that you don’t ship internationlly. How is it possible to buy a Mayfly in Europe?

It is good if the microSD vertical adapter board sale separately

I designed a simple shield for Adafruit FONA 3G cellular breakout. The shield also include two sockets for SDI12 sensor

ChanCafun: that’s awesome, it looks really good. I assume you didn’t have any trouble figuring out the layout and spacing of the two 2×10 headers. I put them on a standard 0.1″ grid so it would be easy for people to produce their own accessory boards.
What SDI-12 sensors are you using? I don’t recognize those 6-pin connectors, but they look like they might be useful for times when the 4-pin Grove socket isn’t big enough.

Thanks for the user friendly spacing! I didn’t get any trouble.
I am using In-situ Inc Level TROLL Data Logger for water level monitoring.
The extra pins are for RS485(2 pins) and 4-20mA(1 pin). I am not using it now but I may switch from SDI12 to RS485 in future.
I may purchase more Mayfly data logger in future. The microSD vertical adapter is necessary in my design because my logger enclosure is narrow. It is good if the microSD vertical adapter board sale separately in Amazon

Hi ChanCafun, nice pics of your system.
Which Level Troll are you using? Have you had any deployed for any period of time. I’m currently working with Level Troll 500.
I’m also looking at the RS485. The real issue is the power management, and generating a switched +12V that is typically required in a RS485 level-troll or Keller Nano-level, oh, and of course doing it off a Li-Ion or its more enviro friendly cousin LiFePO4 battery.

I am using Level Troll 400 .
For the current setup(using Mayfly datalogger) with cable length 1 m to sensor, I only test it in office for four days.
Previous setup(replaced by Mayfly now) using Pro Micro, SD breakout, RTC breakout and 3G breakout. I tested it in office for 21 days.
Both test result were good. But still need to fix some minor problems
I will put it to site for testing in coming few days
