I have been asked if I had a uBit Raduino by many who bought RaduinoX PCBs.

I have sold over 50 X PCBs and tested units.

Well I finally got a few built and tested today.

The Big Extra is I added an I2C Bit Expander.?? This add 16 MORE I/O ports to fiddle with.

2 - 12 Pin Molex Connectors add 16 I/O and some +5V and Ground pins, as well as some control pins

for the Microchip Expander IC.?? You can use Adafruits Library MCP23017 to create 16 more Digital Pins.

You can see from the pictures it squeezes in just like the original.

I tested it in uBit today with a signal generator.? The only antenna I have is a 40M copper pipe loop.

There were NO signals anywhere!? Not even my BitX buddy at 7.200 MHz!

The Signal Generator was heard way down to about 0.4uV at 3 and 10 Mhz.??

So, the receiver seem to work fine.

Rainy weather and an RF dead day!

email me for any more info...
