What LCD is used in the Pixl.js? Datasheet? OSHW?

Ok, I just stuck a Pixl on Nordic's power profiler, which seems to do a pretty good job. It definitely doesn't appear to have ranging issues, and it can average power consumption over a 7 second period (although readings do vary over time by maybe 5%).

I did NRF.setConnectionInterval(200) which forces the device into 200ms connection interval, so I can stay connected while using about the same amount of power as when advertising (maybe just a smidge more).

• Normal power consumption: 216uA
  
• lcd_standby(0) - 66uA
  
• lcd_standby(1) - back to normal, 216uA
  
• lcd_sleep() - 65uA
  
• LCD physically unplugged - ~60uA
  
  

So it looks to me like the deep sleep doesn't really save you much over normal sleep at all, unless I'm missing something.

Anyway, this is really good news - looks like Pixl.setLCDPower will do a pretty good job without even having to re-send the LCD contents.

(on an unrelated note, I added a temperature alarm to my freezer. It turns out the DS18B20 temp sensors use about 4x more power than the whole Pixl if you leave them on!)
