Eventually, I hope to have two apogee pyranometers on the same board as well, the SP-510-SS and the SP-610-SS. Because there are only four ADC pins (as far as I understand how the board works) it looks like I have to take single-ended measurements instead of differential…[Read more]

I was also wondering, Shannon, if you might be able to help me out with something. I’m looking to attach a suite of sensors to the Mayfly that have a mixture of analog outputs and digital outputs. I’m worried that I won’t be able to get all the sensors I need with this data logger. Is this something I could talk through with you?…[Read more]

That definitely helped. I think the only thing I’m still confused on is the output channel. You mentioned that the white wire in the uppermost grove jack is connected to analog channel zero, but when I look at the board, the label next to that wire is AA1. If you could clear that up for me that would be great. Thanks for the help!

I am new to electronics and microcontrollers, so there could be a lot of places I am going wrong here. I am using a Mayfly version 1.1 as the data logger. To connect the sensor, I am using the Aux Analog grove terminals. I’ve attached a picture of my…[Read more]

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]

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.
