![]() I searched for quite a while before coming across this post and even then it was with the aid of a colleague I was brand new to Arduino and was of course very disappointed when I could not get the simple Blink sketch to load. This procedure fixed my problem on Mac OS X 10.9.1 with Arduino 1.0.5 and an OSEPP Uno R3 Plus After disconnecting the Uno, the Mac rebooted as normal, so no lasting damage done, but I am a bit wary of trying to plug the clone in again.Īnyway, note that the chip says CH340 on it, but the drivers are CH341. I downloaded the mirrored driver, rebooted the mac, and when I connected the Uno, my MacBook died and restarted with the grey serious error screen and refused to boot. After a bit more googling I found the kiguino site. Once I realised that I found the USB转串口芯片 CH340 - 南京沁恒微电子股份有限公司 site, but the Mac driver doesn't appear to be there. After inspecting the board with a magnifying glass, I saw that I did not have an FTDI chip in my Chinese clones of an Uno and a Mega, but a CH340G instead. Yes, I have been struggling for a month or so, and finally realised (after reading Arduino in OS X 10.9 Mavericks - Serial Port Issues - IDE 1.x - Arduino Forum) that other chips were being used, in lieu of the FTDI chip, for example the Prolific 2305. ![]() I bought a UNO R3 ATmega328P CH340G USB Driver Development Board - IDE 1.x - Arduino ForumĪnd another blog site that explains the whole process really simply for noobs like me:Īctually the dude has even mirrored the relevant driver that solves the problem without having to find it on an all chinese or all russian website! For any others who haven't been able to solve this one yet: if, like me, you decided to go with the cheaper chinese kick off arduino clone boards and had problems similar to this one, please check the following forum post, as it solved the problem for me:
