When the serial port is closed, the DTR pin goes from low to high. But since the capacitor in the reset line is already charged by this point, the voltage on the RESET pin becomes 2xVcc (DTR + capacit…

Hello, i have a brand new nrf52840 development kit with jlink on board
When it arrived, LED was blinking (the one near actual NRF chip.
However, when i tried uploading simple code

Sometimes, a few simple components are integrated into the harness, like e.g. a LED indicator or switch mounted at a connector housing, a resistor at the end of a bus line, diodes for protecting again…

Here's a lesson I learned, and an enhancement suggestion. I accidentally reversed the power on VIN for less than 1 second. It didn't fry my $7 Uno knock-off, but I heard it instantly pop the microsc…

Chances are that it will be destroyed, so we can think it as a **sacrificial device** ;-)
...it costs a few bucks :-)
Better this than your main PC!

Verified my logic and the probe is functioning... Voron 2.4 r1 Octopus 1.1 never needed a diode and ran klicky standard without issue. Thing is, the LED is always on dims briefly while probing..

It is still under development, just need a polygon pour to connect GND pins

1N5817 is solid for add-in USB-backpower protection diode purposes, but could be swapped /optioned with a lower forward voltage alternative if a SOD123 surface mount pad option was added. The surface…
