This daughter board is being revised and replaced by a USB version. ETA is 4th Qtr 2010 I2C Relay Daughter Board gives you control of 6 SPDT relays for general purpose use via the standard I2C Bus. Up to 7 relay boards can be daisy chained together for up to 43 seperate relays on a 4 pin connector. Each board also includes a switched 4.3 volt output useful for driving an IO line high ( Ex. To reset a computer ), to drive a larger external relay, or for general purpose. A status LED shows communication with the I2C host.

A handy addition to the RMS V1 with firmware 1.70+ and RMS V2, or any other I2C controller. (NOTE: Does not work with RMS-200 board. A new USB version for the RMS-200 is expected by the end of 3rd Qtr 2010)
