Cool, thank you Steve for the measurements, as these will provide enough information to approximate the size of battery I will need

John Smutny replied to the topic XBEE Module in the forum Mayfly Data Logger 8 years, 4 months ago

Would there be a way to send data from a Digital pin to a XBEE pin under those principles (for example, take data from pin D4 and send it to XBEE pin DIO4 to be transmitted wirelessly)?

Right now I am trying to using the XBEE port on the Mayfly to transmit data to the Digi Cloud service in order to graph sensor data wirelessly on-site. Moreover,…[Read more]

Done, thank you for the help

John Smutny replied to the topic Ver 0.3 Mayfly Grove Power Supply in the forum Mayfly Data Logger 8 years, 4 months ago

Ok, I have checked the datasheets to my sensors and none of them output a voltage greater than 3.3V (2 are digital sensors while another supplies a max of 2.4V), so thanks for the heads up.

Unfortunately, I do not have any experience replacing regulators on a SOT-23 surface mount, therefore I am curious on how soon this replacement process can…[Read more]

Problem: Haven’t been able to send 5V power to the Digital and Analog Grove Headers. The Headers are constantly supplied with 3.3V

I have a question about the Notice on the Mayfly “Jumper Settings” page regarding the board’s internal boost regulator (here is the note)…

“Note: due to a manufacturing issue on Mayfly version 0.3, some boards have…[Read more]

Right now I am trying to power the mayfly using a battery pack, but I am not sure how much power the Mayfly and all of it’s applications (XBEE port, SD card reader) consume. I am only concerned with powering the on board applications, since all external sensors have there own power needs. Are there any references to the power or current…[Read more]

The mayfly acts in a similar way to other boards, such as Arduino, that can take analog and digital inputs and connect to the mayfly. Through my experimentation, what ever works on Arduino will also work on the mayfly

That sounds good, thank you for all of your help

John Smutny replied to the topic Mayfly USB Connection Problems in the forum Mayfly Data Logger 8 years, 5 months ago

Currently my computer is running on Windows 8, 32-bit, and i am connecting the Board using the provided USB cable from the starter kit, and 3 other cords still have the same problem. But, I haven’t tried programming the board using the FTDI port yet and can test that when I gather the equipment.

In regards to testing whether the switch removes…[Read more]
