I have discovered that some of the newer 20x4 LCD displays work at 3.3 volts.
Dimmer than at 5 v, but still quite usable. Just think, direct connection
to a Pi, Beaglebone Black, or PCDuino without level shifters.
Has anyone tried these particular displays at 3.3 volts?

Download a bootable Ubuntu image for the PCD Lite here:
Note that the Ubuntu image for the regular PCDuino doesn’t seem
to work on the Lite. Note also that when expanding the partition
to the max size of a 16 GB micro SD card, resize2fs takes about half
an hour to run. Probably correspondingly longer for a 32 GB card.
So, be patient.

These little redboards are great for prototyping with a solderless breadboard.
Just make one change when assembling – use stackable headers instead of the
supplied ones. The pins on the stackable headers need just a little tweaking
to get them to fit into a solderless breadboard, and voila, you’ve got a complete
hardware development system. And if you should somehow blow the ‘328, just get a new
one for a couple of bucks and plug it in.
This item is a hidden treasure, and Sparkfun should do more to publicize it.

Well, the next version of this board will probably be a killer.
Here’s what the pcDuino needs.
1) Get rid of the semi-compatible Arduino headers and instead
have a socket for plugging in an ATM328 coprocessor daughter board
that accepts Arduino shields with no adapter needed.
2) More video output options, including RCA jacks for NTSC/Pal monitors,
a VGA jack, more HDMI video modes supported, etc.
3) Socket the SOIC chip, so it can be replaced if blown.
Well, hey, I can always dream.
You know what the pcDuino needs to make it a runaway bestseller?
A conversion kit or set of cables to enable it to interface with
a Motorola Atrix lapdock, just like the Raspberry Pi can do.
Yeah, so for under 100 bucks extra, you can get a single-unit HDMI display,
with keyboard and trackpad to hook up to the pcDuino.
Is this doable, or what?
No public wish lists :(
