Re: Low voltage warning with DC/DC Buck converter

Hello, Based on the suggestion that my breakout cable used wires that were too small/thin, I built my own USB C connector. With my home made cable and connector, the lightning bolt and low voltage errors have gone away. For anyone else who might be in a similar situation, I used 22 AWG wire for this...

Re: Low voltage warning with DC/DC Buck converter

Hello LTolledo, Thanks for the feedback! I am powering the Pi using a USB C breakout cable from the buck. I'm not sure what the gauge of wire is inside of the breakout cable. All of the other internal wiring, barrel connector, cooling fan, rocker switch, and buck input, are connected using 22 AWG wi...

Low voltage warning with DC/DC Buck converter

Hello, Context: I'm running a Raspberry Pi 4 in a SmartiPi case with a Raspberry Pi 7" display (powered off the GPIO pins). I'm running a fresh install (updated today) of Raspbian. My ultimate goal is to run this off of my ham radio power supply (which provides 13.8vdc). I'm using a XL4015 5A D...

Raspberry Pi 4 Reset Button?

Hello, I'm trying to add a reset button to my Raspberry Pi 4. Previous versions the the Pi (2,3, and 3+) required that I briefly short a pair of pins near the USB connectors (no programming required). The new Pi 4 has PoE pins where the reset pins used to be. Is it possible to reset the Pi 4 like th...

Re: Mouse issue after rpi-update

This fix worked for me! I'm running a Raspberry Pi 2 connected to a Avocent Cybex KVM which is connected to a Logitech K360 wireless keyboard and mouse.

Re: RS-232 RTS voltage levels?

Hello, I spoke with Yaesu's service department regarding the PTT trigger. They said that PTT is activated when the microphone is shorted (grounded). I've cobbled together a drawing using the Yaesu FT-60 manual's drawing (pg 11), k6vug's drawing [k6vug], and a drawing from the Yaesu MH-34B4B speaker/...

Hello Hippy, As luck would have it, I have a Prolific PL2303 cable on-hand for consoling Cisco devices : ) I agree that probably any pin capable of providing a signal could trigger the PTT, assuming the PTT can be triggered by a 3.3v signal. I'm not sure what options are available within the SoundMo...

Re: RS-232 RTS voltage levels?

Hello Burngate,

Thank you for the great explanation! I've e-mailed Yaesu asking for the PTT trigger signal level. Hopefully it's not above the 3.3v the Pi provides.

If the trigger requires something higher than the 3.3v I suppose I'll try my luck with a USB to RS-232 adapter.

Thanks again,
