Chip PC Technologies EX-PC: Hardware 

• Hardware
• Firmware
• Linux

This Chip PC Technologies thin client is a small and neat unit. It is very clearly marked EX-PC on the side panel and elsewhere carries the model number XPD4741. However, their website in May 2014 shows the EX-PC as a totally different beast based on an AMD dual-core processor. (Don't you hate it when they change the hardware but not the name?). Their website is totally anchored in the present - even using their search engine and the term XPD4741 returns " did not match any entries", but using Google you can find some datasheets that they're holding.

The XPD4741 is a rebadged Clientron U800 series thin client which is also marketed as the 10ZiG RBT-616V).

Expansion

As usual, clicking on the photo (right) will take you to a larger scale photo of the circuit board.

It is fairly compact in size so there is little space to fit anything internally.

Flash: The Flash memory is replaceable. It's a DOM plugged into a standard 44-pin IDE connector.

RAM: The RAM is a single DDR2 SO-DIMM. The Clientron datasheet for the U800 says that it supports: "DDR2 400/533 from 256MB to 2GB"

Wireless: The datasheet does mention "Optional WLAN module" but originally I didn't look into how this is fitted. In March 2020 Pete pointed out a Clientron U800 data sheet that says "WLAN: Option (Internal USB header for WLAN module)"
