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]

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]

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]

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]

Through my experimentation, what ever works on Arduino will also work on the mayfly

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]
