The TASS Coax Relay System
The TASS (Totally Awesome Switch System) is a general purpose 8 port
DC-150 MHz relay-based switch. The hardware is designed to be very generic,
with an inexpensive processor such as an Arduino providing the system logic.
Control is via USB, with ethernet and other interfaces also available.
The TASS-R and TASS-SHIELD interface board for Arduino are now available
from TAPR and you can
order them here.
