Recommended Posts

Hi all, 

I'm currently doing a project consisting of msp 432  launchpad along with cc3100 BOOST. I need help in powering the msp and boosterpack from an external supply.I have a a 5v and 3.3 v regulator with me. Please help.

Check the data-sheets for power consumption, especially the peek required by the CC3100 WiFi radio.

 

5V and 3.3V power rails are exposed. Check the schematics for the connecting the external power correctly, and for isolating the programmer/emulator part.

@Rei ViloI have 5 V and 3.3 V regulators setup with regulator ICs which are fed with a 12 V DC supply. I read in the document that while powering separately, we need to power the booster pack prior to the launchpad.So can I power the MSP launchpad with a 3.3 V and just plug in the boosterpack and place the jumpers so as to receive power from mcu.

Thanks for the help, Sir.
