I had looked through the power up sequence page previously but wasn't sure how much of a requirement everything was (it mentions a USB voltage regulator needing power but assumed that was to convert 5V to 3.3V for powering the chip, something I'm doing externally). I was reading through another...

Hello, I have a project where I need to power a Teensy 4.1 from 3.3V. My current setup is as follows: - I have cut the VUSB/VIN pad jumper on the bottom of the Teensy - I have connected a CR2032 to the VBAT pin to keep the time management circuitry alive before connecting USB/wall power - I...

Hello, I recently purchased the Ethernet Kit for the Teensy 4.1 and I have been trying to check the link status of the device as just a first test to getting the device working. I went to the examples folder and found the NativeEthernet > LinkStatus sketch and uploaded that without any changes...

Awesome, thanks for all the info and quick responses. I really appreciate the help and the Teensy products is great to work with!
