News - Fluke, we love you but yo… |
Today (March 20, 2014), Fluke reached out to us. Here is their public statement. SparkFun has officially accepted their gracious offer and will be donating the Fluke multimeters to several educational institutions and schools.
Good on you, Sparkfun. And good on you Fluke.

I fail to understand why Sparkfun never seems to breakout the shutdown pin on any of their breakout boards! Why do I have to cut a trace and solder a jumper wire on and SMD part to get it?

Can anyone confirm what the lowest current consumption should be on this board? The 328P datasheet suggests that I should be seeing under 1 uA with maximum power reduction in place, but the lowest I’ve been able to see is about 102 uA. And that’s with the LED1 removed from the PCB.
The datasheet for the MIC5205 regulator shows a typical ground pin current of 80 uA at a load of 100 uA. With the 328P in full shut-down, it should be presenting a load of < 1 uA. There is no data in the sheet for loads that low, but I imagine the ground current would be at or below 80 uA. The enable pin has a typical draw of 5 uA.
That’s a total of 85 uA typically for loads of 100 uA, so the total current for a < 1 uA load should be somewhat lower. Why am I seeing consistently 102 uA? Is this the best that I can expect?
No public wish lists :(
