No! I'm pretty sure the footprints for these chips are different; double check the data sheets before you do that. The 3.6 doesn't hurt anything since the voltage goes through the diodes; its closer to 3.3-3.4v

Hi there,


I dig up this topic because I've been sent a v3.3 module soldered by an inexperienced saabist that didn't worked at all... and for good reason, there were shortcuts all around RN52, MCP2515, diodes and LEDs upside down, etc.


I've been able to bring the RN52 back to life and cleanup every bad soldering but a chip didn't stand the treatment : IC3 voltage regulator which was a Micrel 5209 3,6V series on this pcb.



Should I replace it with the same chip or can I use the one used on the latest PCBs (i.e. NCP1117ST33T3G) delivering 3,3V ?



Thanks guys
