For a configuration with a LiIon battery that is at low outdoor temperature, say -10C, the available power is more limited than at a summer temperature. To determine available power,...

Mayfly 1.1 has a new option SJ27, that allows the Vbat measurement to be connected directly to the LIPO_V. Thanks shannon. ModularSensors (0.32.2) Vbat algorithm connects the AREF signal to...

The Mayfly 1.1 Sn 22059 with the new SJ27 set to LiPo Vbat measurement is not linear for reasonable battery measurement of Vbat in the range 3.6to 3.9V charging from...

Here is a closer look at the filtering about the 3.8V threshold. 3.8V was chosen as a "safe" threshold, a) for the LiPo battery and b) for the linearity of...

For the Mayfly 1.0 revA3, the +12V boost is implemented with a nice chip called MAX17250ATD+. https://datasheets.maximintegrated.com/en/ds/MAX17250.pdf This uses a 2.2uH inductor for the boost, and requires a specifically designed...

@s-hicks2 brings up the challenge of 2021/22 - supply shortages on devices, so annoying. Seems to me though that what is needed, is to define the minimum power rating to...

Using Mayfly Sn21260 + Flat 2.5Ahr battery. Some characterization readings, using simple blinkPower that turns on power 10sec and off 2sec, with a Resistive load that consists of variable 75W/Power...

Just wondering if this is still a relevant, or has it been superseded by other features?

Just a thought, if considering how a field technician (non programmer) without a computer, is using or visiting the site, it might be good to have a clear LED sequence...

I have NTP/UDP over WiFi working on the Wio Terminal.
