 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

Referring to KeepIS' post on page 8 of this thread re: removal of diode and capacitor from nano board rear side. I received two slightly different nano designs, one of which I (think) I've identifed the diode and capacitor. The other one at the top is less clear. Anyone want to have a stab at identifying the relevant diode and capacitor? Soon to attempt firmware downloads ahead of commencing the build.  |

The second one is correct, these can be supplied with a newer USB-C connector as well, I have just confirmed that both types work, and they are indeed the correct components to remove. As a refresh: 1: The Diode isolates the USB external +5V from the Nano controller. 2: Cap removal stops the USB Port from resetting the Nano controller on port connection and when connecting to a Serial program for setting the Menu options. The First Board? I will have to look when I get a chance, not sure I have one exactly like that? They can be in very odd places on some boards. EDIT: No the First board is non standard, I do have a couple, I could not isolate then from resetting the Controller. Use them for the LCD display or better still, the poida Saturation tester. : Edited 2026-09-04 12:06 by KeepIS NANO:Inverter V 8.4ks - Linux AvrDude GUI script V4.1 |
