Hi Shannon. So I just received a few more panels. The stereo jack cables are going in relatively easily with these. I think I received some damaged hardware, causing the stereo jack cable to be very difficult to get plugged in. And causing a bad connection to the logger.

I’m very much a fan of ModularSensors and the discussion board as a place to be real with technical issues. I do so appreciate the unique place EnviroDIY has been curated to be, to try some remote wireless terrestrial monitoring. Its the nitty gritty of environmental monitoring and the engineering it takes. Its tough to find out what these ser…[Read more]

Am I correct to assume that the payment page will open after the first? I tried to pay for 2024 now and got the message “This product is currently out of stock and unavailable.”. Thanks.

I have a multimeter that can measure amperage. I’m not sure how to get it inline with the circuit though without putting together a couple wires with the proper jst connectors…I’m not an expert in this and don’t want to short the board.
Any suggestions on where on the board or how to test?
Thanks!
James

I haven’t had much luck getting to 0.5mA with mega1284, it was with the Mayfly 0.5b- https://www.envirodiy.org/topic/testing-power-consumption/#post-15252 My notes on measurements is that it was between 2-2.5mA. I did get well beneath 0.5mA on another project with mega2560, but that was a lot of hardwork, and also ended up with a higher valu…[Read more]

You could also try putting an ammeter in line with the main battery (with no solar or USB connected) to monitor the current of the board during use. When it’s sleeping, you should see a current of about 0.6mA for your configuration. If you measure a sleeping current above 1mA, then something is probably wrong, either the board isn’t properly sl…[Read more]

Thanks for all your help. I believe that the bigger solar panel with >1A peak current, a 1A charging current to the board (jump SJ15), and a freshly charged battery should remedy the winter issues.
Regarding consumption, I took one unit home, mostly charged a LiPo 3300mAh battery, here is what I found (no external sensor connected, transmitted…[Read more]

@jp – the charger relationship doesn’t quite work that way. The 5V 2.0A is typically the stated maximum the charger can supply – however for the battery charger circuit there are limitations. I use a USB Meter to determine what is actually going on.
The Mayfly 1.x charger circuit is to 0.5A as default but can be changed to 1.0A. I always change…[Read more]

Thanks Shannon. I was actually talking about the stereo jack. See attached image.
Since we transitioned to the new panels it has been very difficult to get the stereo jack from the panel plugged into that adapter cable. Any recommendations on that are welcome.
