There are times when your budget is not enough to buy the Original Arduino boards. An original Arduino Uno is priced at P 1,100.00 at the official website (arduino.cc). If you’re a student, that’s a lot of money, so your only option is to buy the cheaper alternatives which is priced at around P 350.00 to 450.00, a big savings right? The only difference is that the USB to serial chip is being replaced by a chinese-made chip, CH34x.
After buying the cheaper board and plugging it in your PC, you noticed that it’s not working or the arduino IDE can’t detect it. Don’t panic, you just need to download and install the CH34x driver.
Here are the steps:
- Download the driver here. CH34x-Driver-Windows
- Unzip the file
- Run the installer, CH34x_Install_Windows_v3_4.exe
- In the Arduino IDE when the CH340 is connected you will see a COM Port in the Tools > Serial Port menu, the COM number for your device may vary depending on your system.
- If you run into problems, just visit the manufacturer’s site. http://www.wch.cn/download/CH341SER_EXE.html
- Download the driver here. ch340g-ch34g-ch34x-mac-os-x-driver-master
- Inside the zip file you will find a PDF and a “pkg” file, short version, double click the pkg file, the PDF has some extra information.
- If you run into problems, just visit the manufacturer’s site. http://www.wch.cn/download/CH341SER_MAC_ZIP.html
- The Driver is almost certainly built into your Linux kernel already and it will probably just work as soon as you plug it in.
- If not, you can download the driver here. CH340_LINUX
- If you run into problems, just visit the manufacturer’s site. http://www.wch.cn/download/CH341SER_LINUX_ZIP.html
