Re: #qmx Don¡¯t Use USB-C PD to power your QMX?! #qmx
¿ªÔÆÌåÓýDon,I assumed the added current limiting resistance. ?It¡¯s just that I had not seen this as a recommendation to protect the QMX and control the ?usable voltage to the advised 12 volts. A friend recently recommended that I use a 12 volt Zener in my supply line from my batteries because fully charged they are over 13 volts¡¡ versus the ¡°standard¡± diodes in series and having to short them out as the battery voltage dropped.? Thanks for your thoughts. ?I am still learning after 63 years in this wonderful hobby. Dave David J. Wilcox¡¯s iPad On Sep 4, 2023, at 11:21 AM, Donald S Brant Jr <dsbrantjr@...> wrote:
