Dear EnviroDIY,I’m working on setting up a sensor network with a variety of soil moisture and temp/rh sensors. We’re using a CS-215 to handle temp/RH and it requires 12VDC. The trick is that we obtained our Mayfly via a colleague at another institution and aren’t sure if the board is 0.5 or 0.4. Obviously if it is 0.5 it can handle the 12V needed for the CS-215, but if it is an earlier version, the board will fry.
Is there a recognizable feature between the two that I could use to discern what version I have? All the sensors are using SDI-12 so I’m not particularly worried about things on the sensor output side.
Thanks!

I have a version 3 and a 5b sitting next to me and both have the version number right by the on-off switch. It’s also printed on the back of the Mayfly to the right of the name.

Yes of course! Just checked – we have 0.5b. Don’t know how I overlooked that!
Another quick question that you may/may not know – if you are connecting an external 12v powe
Hi Beth,Yes of course! Just checked – we have 0.5b. Don’t know how I overlooked that!
Another quick question that you may/may not know – if you are connecting an external 12v power supply to the mayfly, what type of jack is needed to connect the power source to the Mayfly? Is that just a male JST jack? (pictured here: jack)
Thanks!!

2018-03-12 at 3:59 PM #12195I got that connector from All Electronics: https://www.allelectronics.com/item/con-242/2-pin-connector-w/header-.10/1.html
Any 2-pin header with standard 0.1″ (2.5mm) spacing will work, though
I got that connector from All Electronics: https://www.allelectronics.com/item/con-242/2-pin-connector-w/header-.10/1.htmlAny 2-pin header with standard 0.1″ (2.5mm) spacing will work, though I prefer the ones from AllElectronics because they’re polarized and come with the prewired matching cable with 8″ leads. They’re made specifically for that company, so you can’t find them elsewhere.
Otherwise, you can use a basic Molex 2-pin polarized header, but then you’ll also need the mating jack and crimp pins.
