Program and debug sx28 @ low voltage (2 - 3.3 V)

MarcoPyoyoyo

Hello,

What about SX Key Ring - Stock code #45211 that is in the SXBrochure2006.pdf ?

Is possible to program and debug an "in-circuit" application that need a supply voltage of 2 - 3.3 V with sxkey tool?

I don't see the SX Key Ring in PARALLAX product section, Is there any other tool to do this?

Thank You

All you need to do is connect the SX-Key Vdd pin to +5 and connect the other 3 pins to the SX as normal.
If you have a 5 volt power supply it wouldn't take much to make a little adapter.
At 3.3V you would be okay. I don't know about 2 volts though...
