ThinCan DBE62

The DBE62 retained the AMD Geode LX design used in the DBE61, upgrading networking capabilities to VIA VT6122 Gigabit Ethernet controller and adding expansion possibilities for an optional internal USB extension daughterboard, serial port daughterboard or combined USB plus serial daugterboard.

Variants

  • DBE62D-700: 512KB NOR Flash for BIOS, 256MB DDR SDRAM, 64MB NAND Flash for OS payload — delivered with an LX700 as preproduction samples.

Driving the DBE62

  • The DBE62 is covered by the same Linux and X.org drivers as the DBE61.
  • The VIA VT6122 network controller is covered by Linux kernel module via-velocity or by the VIA Linux driver velocityget available from VIA Arena.
  • If you need to swap phone out and master channels for the audio, the following kernel command line snippet can do that for built-in drivers:
snd-ac97-codec.ac97_quirk=swap_hp cs5535audio.ac97_quirk=1

Booting the DBE62

The DBE62 benefited from the Coreboot development efforts made for the DBE61. Support in Coreboot-v3 is good, but extensive testing and stress testing is still to be conducted.

USB daughterboard

DBE62 has an additional header on board, where 2 of the USB ports are looped through. Artec has designed an extension board that can be plugged into this header. The extension board has an USB hub and 2 internal USB A ports; one of the Geode's physical ports is connected to one internal port; the second Geode port is connected to USB hub, where another internal port and 2 external ports are routed back. The internal USB ports can be used to add more internal hardware in the case (i.e. WLAN module, GPS module, etc).

Serial daughterboard

DBE62 has an added header on board, where the second Geode serial port is routed (TTL levels!). Artec has designed an extension board, that contains TTL-RS232 converter and DB15 connector. The extension board can be installed to bring out the DB15 connector on the side panel of ThinCan. The serial port supports RS/TX and RTS/CTS lines.

12V output board

Artec has designed an GPIO output expansion board for ThinCan. The board connects to LPC header and the software can mux the LPC data pins to GPIO outputs to control the board. The board has 12V input and 4 NPN transistors to switch 4 outputs (negative terminal is swiched). The board is installed as one side panel of the box; it has 5 detachable 2-pole screw terminals.
