The wireless ARMmite was a spec design for our SparkFun distributor. Built to their parameters and sold for a number of years. It has been retired as a product.
However, there has still been a great deal of interest in wireless connectivity. The Zigbee standard is a good match for low cost, low power data connectivity. Coridium combined the BASICchip, Zigbee and LCD display into a compact demonstration unit. This board mates with a standard Newhaven display and provides a number of IOs analog and digital, with 2 configured for 4-20mA sensors. It also has an optional power supply that can accept up to 36V.
This device has not been produced as a product, but is available for OEMs.
