It's always a good day when a box arrives covered in Chinese writing. Especially when you check things and it all looks correct! :D

Had a bit of a mare though!! seems i made 2 different 3.3v circuits on the board, and only attached one of them to an actual 3.3v source!! just one wire to fix, so its not a total loss.

So i thought i would do the obligatory power test on the new board

we are running a new Zero W, with wifi and bluetooth on, keyboard and mouse attached via the bluetooth (microsoft wedge)

fired up firefox and clicked the first youtube video to keep the cpu at full tilt, and the most i saw on the power meter was 0.26ma
Image

sat idle on the desktop was flitting round the 0.13ma mark
Image

had it on while installling the xserver and xfce desktop environment, and some playing, and its only used just over 300mah in just under 2 hours
Image

now even if my previous tests showing the guage is about 10% out, thats still not bad!!!!

So I got my zero and PiCB-tft all soldered up last night, but by the time I had everything set up and a fresh SD downloaded and installed it was time to leave the 'space... so didn't get to properly play.
I'll take a pic and upload it soon enough ;)

yay!!!

im actually pretty impressed with the pcb's. the edges are all nice and smooth, and the finish is pretty good too for the money!

I forgot the wire mod you mentioned and still haven't been able to boot it up yet...

very nice!! i especially like the resistor bending skills!! Without the 'fix' wire, the screen wont work. although your resistor is close enough to the gpio pins that you could bridge from 3.3v to the resistor instead of using up those 3.3v connectors at the bottom

whats the extra little board? is that the charge/boost/protect board you mentioned the other day?

Ooh. good call. though i was going to replace it with a SMD resistor as soon as i got hold of one. but a kynar mod is still doable anyway... ok :)

yes, a tiny one for the VMU, which I'd forgotten that I was waiting for. :oops: once the USB A socket is removed (other side of the board) and I swap the overly large inductor for a lower profile one (incoming from RS at half the cost of the board just for the inductor! - only because I didn't want 10x of a cheaper one)

anyway, will you still have any of these screen/board combos left or are they all spoken for?
