![]() ![]() There may be a different USB-serial IC on the other side of the USB board. 'Chinese documentation' is one of those oxymorons like 'military intelligence', 'jumbo shrimp', or 'Kennedy School of Government'. The USB - serial converter does not appear to have brought out the DTR pin from the CH340G (verify that it actually is a CH340G). Check the connections with a voltmeter's continuity_checker/beeper. ![]() ![]() Sometimes these Arduino clones have the header pattern of holes reversed, sometimes the silkscreen is reversed, and sometimes they're all correct. Unless they are reversed and the hole that is actually closer to the tiny capacitor is the DTR. The reset capacitor is above the pin marked RAW. The DTR pin is the one in the corner marked BLK.
