Hello Forum,
 

I have a need to develop a 3.3V circuit using the SX28.  The whitepaper gives the range as 3-5 volts, so I should be in good shape.  I assume I'll need to program the SX with my biltz and PDB (serial line is 5V), and then remove the chip and put it in my 3V breadboard circuit.  Any way to allow the SX to stay in place on the PDB, but be powered by a 3V regulated supply on the breadboard?  Sure would make my life easier if this is possible.  Anyone tried this before?  Any ideas?

 

Regards!
