Duckbill 2 485


ARM9 based Linux Server with Ethernet and RS-485 interface in a thumb drive format

Duckbill 2 485 is a tiny ARM9 based computer in a thumb-drive format with an interface for RS-485 communication. It is intended to be set up as Ethernet to RS-485 gateway but can also be used as a small home-server for automation purposes. The default delivery option contains a software for bridging the RS-485 to Ethernet. Nevertheless the device is programmable in all common Linux programming languages.

Duckbill 2 485 is available in two different variants:

  • Duckbill 2 485, the USB powered variant
  • Duckbill 2 485+, powered via 24 V supply connector.

Duckbill 2 485 can be powered either by a USB power adapter or via a USB port of your router.

The open software approach enables comprehensive further development of software by the community.
