Devon IT: TC15 

• Hardware
• Disassembly
• Firmware
• Linux

The TC15 thin client was launched around September 2014 along with the TC20. It was announced by CloudTerm. I have no idea who CloudTerm are but suspect they were part of the Devon IT stable. The website cloud-term.com existed between 2015 and 2017 but as far as I can see from the 'wayback machine' was fairly content free and devoid of ownership/contact information. It also did not get updated during its lifetime following its appearance in 2015 through to its demise in 2017.

The TC15 is a neat and small unit.

The TC15 was shipped with either Devon IT's Detos operating system (Linux) or WES7. My unit came wiped clean.

Power Supply

The unit came with a standard external 12V 3A supply. I don't know whether this was original or not. The plug is a standard 5.5mm/2.5mm coax plug.

Expansion

There's no space available for squeezing additional hardware into the case.

Flash: The Flash memory is easily replaceable. It's an mSATA card plugged in to the top of the motherboard..

RAM: The RAM is a standard DDR3L SODIMM mounted on the rear of the motherboard. The unit came fitted with a 2GB hynix part: 2GB 1Rx8 PC3L-12800S-11-13-B4 (HMT325S6EFR8A-PB). I did try out an 8GB Hynix part (8GB 2Rx8 PC3L-12800S-11-13-F3) that worked.

mPCIe: There is a mPCIE socket on the rear of the motherboard. I assume this is for the usual WLAN option

Links: On the top of the motherboard adjacent to the ethernet socket is a conventional 3-pin link field for clearing the CMOS memory. Briefly move the link to the two pins furthest from the ethernet socket to reset the CMOS contents.
