You need to add a CPU
No, that is embedded on to the motherboard. Normally it’s a Intel ATOM or AMD E-xxx Series. Most dual core as well ;)
a hard disk
Most modern BIOSes support booting from USB flash drives ($5), so no problem there.
a hefty power supply
A 45W PSU should work nicely.
a wireless I/F
Only a additional $6 from DX
For that price… I would rather have a Mini-ITX motherboard (like this and this). Of course you have to purchase ram, but it can be bought relatively cheap these days.
As for GPIO… Bitbang the serial/parallel port or use a FTDI FT-X series converter to handle that.
I really don’t understand the idea of integrating a MPU (along with minimal support components) with no expansion capabilities other than low speed serial interfaces. Perhaps i’m the only one who thinks that…
Interestingly enough, a SHT15 Breakout Board will mount (almost) perfectly within the case.
Or, you can save more than $10 if you have sampling privileges, or know a overseas “SparkFun” shop ;)
It’s sort of like how hulu works; pay a premium for something now (or in red) or wait a while for someone to release the same exact board (Thanks OSHW!) often in blue at a fairly more reasonable price.
The datasheet doesn’t include the actual dimension data, but rather includes a link to another document that does have it.
It’s a physical design limitation, And it is valid until 2199, not 2099. Smart software could compensate by maintaining it’s own century counter in the RTC’s SRAM. However i doubt this device could last more than 200 years in the field. Wikipedia has a nice article on semiconductor failure modes if your interested.
Anyone else have problems with the PCDunio USB Micro-B connector used for power tearing off the board after a few connect/disconnects?
Well, the case is not transparent but translucent. Black would give the most contrast, or a clever lighting setup using the case itself for lighting diffusion.

Depends on how waterproof the case really is.
