So what do those pins (on/off, prog, vbat) do? How are they used?

Ultrasinic dish powerline noise Hi Edwin I believe that the MFJ is a 40khz FD detector. In relative terms its expensive for a such a simple device. I believe that a detector with broader frequency response that is not so frequency selectivey...

Thanks Paul! Glad to confirm this. Also good to know regarding the lack of this option on the T4.0

Maybe this is a dumb question. My goal is to charge and program the Teensy 4.1 through the same signal path as is used "out-the-box". Can I simply wire a microUSB-B cable's D+, D-, GND, and 5V lines to the correponding pins beneath the connector...

As someone designing my first PCB and kind of bouncing off all the different free PCB CAD systems for a week or two without finishing anything, I'm curious how you know which part definitions are good, and what does "good" mean? For example, when...

I'm contemplating doing something similar with a T4.1 for an enclosure design with very limited space. I'd like for programming and power to be fed through this stock/primary micro USB connection. Am I okay to desolder the Teensy's micro USB...

The mini flies. PID's not changed. Graupner SUMD protocoll added :)

I have a Teensy 4.1 development board which as we know all of its components are in accordance with the designs and procedures of the developer and the manufacturer. But here I plan to use Teensy 4.1 as the microcontroller of the system that I...

Maybe you've read this already / looking for something more discrete, but Mark's explanation here involves splitting a panel mount cable to program an externally powered Teensy without needing to sever the trace on the board itself: Although...

Thought I'd reach out as this will be my first time diving into PCB design/CAD software/custom circuit creation... I'm building a "standalone MIDI drum glove sequencer" doubling as MIDI controller, but for now it's codename "Chonky". So far...
