Serial to Bluetooth on an EMU BLACK Power Supply question

Hello !
I want to use a Serial to Bluetooth on an EMU BLACK because the Cars CANBUS is 250mbps and CAN to Bluetooth Module Uses 500kbps… So i will need to use a serial to Bluetooth module.
Problem is EMU BLACK doesnt have a 3.3volt power supply, so how do we go around that, or whats an easy tested method to get that ?
Thanks !

Drop in heatshrink tube and forget about it forever.
If you search somewhere else make sure to look for a ‘buck module’.


Someone posted also this suggestion on the facebook page…

No.

This is a linear regulator which drops any delta (12 down to 3.3v) as heat. This can’t even handle 12v in.

This is why I mentioned to look for a ‘buck regulator’ because of the specific way they operate.
