    The sentence in the documentation says that the AREF pin (not the internal reference voltage) is 3.3V by default. That's clearly wrong. Without an external resistor, the AREF pin is 0V by default.

    On this page https://www.pjrc.com/store/teensylc.html is written: "The AREF pin is used to set the analog input range. By default, AREF is 3.3V due to a resistor. External shunt-type reference chips may be connected...

    No, the VUSB pad does not replicate the connector pad. The fuse is between the connector and the VUSB pad. The other three surface pads (GND, D+ and D-) replicate the connector pads, but VUSB doesn't.

    Yes, there are two VUSB tags in the schematic and there are also two VUSB pads on the board. One is a surface pad on the back side, and the other is a through hole. They are connected to each other and the fuse is not...

    There seems to be a bug in the schematic of the Teensy LC on this page: https://www.pjrc.com/store/teensylc.html The VUSB pad on the back side is not connected directly to the USB connector. It is connected to the...

    Well, I have an example running with ADC and DAC, but I'm still unable to find any documentation for the functions. For example, there is a function analogReference(). Where is the documentation for this function,...

    Where can I find the documentation for analogWriteResolution() and analogWrite() functions? The AREF pin is only an input, correct? Michael

    Hello, where can I find a code example for the DAC on Teensy LC? What's the output voltage range? Does the DAC use the same reference voltage as the ADC? Is it possible to make the internal 2.56V reference available...
