Thanks! I didn't realize you could power the Teensy straight off the 3.3V pins. I thought it had to be via USB or the Vin pin. That should gracefully solve my issue. I do have a follow-up question. I noticed you mentioned and linked step-down regulators. Is there any benefit to using these over...

Thank you for the response. Unless I am misunderstanding, it seems that using ballast resistors (presuming there are two -- one after each Teensy's 3.3V output) would cause a sizeable voltage drop at larger currents. I am expecting to draw about 300mA from my 3.3V devices and it is important...

Hi, I am using two Teensys that communicate with each other to handle separate parts of a project. I am currently designing the wiring for my system and need to power some 3.3V devices. So far, I am planning on using the 3V3 ports on the Teensys to provide this power, however this would mean...
