SparkFun's module shows up in an FCC study on body sensor networks. We've also got a new speedometer tutorial and some new products.
Our friends at Nordic VLSI gave us a heads up that our nRF2401 breakout is being used in an FCC study. Near as I can figure, General Electric Healthcare (GEH) wants the FCC to open up the band from 2360MHz to 2390MHz for something called a 'Body Sensor Network' (BSN). GEH wants to snag a rather large slice of the spectrum pie and have it for themselves and their BSNs. Unfortunately this band overlaps with flight test telemetry systems and the Navy is a bit concerned.
Johns Hopkins Applied Physics Labs ran the tests. They had to come up with a way to tell if a new BSN device operating in this 236-2390MHz band would interfere with flight test operations. Checkout the hack they did to push the 2.4GHz Nordics into the 2.3GHz band:
Where's that 15-ft parabolic when I need one?
Onto new products!
Product Update! The Arduino USB Board is now being shipped with ATMega328. The new Arduino USB board is still fully compatible with the Arduino IDE, contains twice as much memory, and uses a faster baud rate to upload sketches.
