What is a Microcontroller?

MicrocontrollerA microcontroller (or MCU for microcontroller unit) is a small computer on a single integrated circuit. In modern terminology, it is similar to, but less sophisticated than, a system on a chip or SoC; an SoC may include a microcontroller as one of its components. A microcontroller contains one or more CPUs (processor cores) along with memory and programmable input/output peripherals. Program memory in the form of Ferroelectric RAM, NOR flash or OTP ROM is also often included on chip, as well as a small amount of RAM. Microcontrollers are designed for embedded applications, in contrast to the microprocessors used in personal computers or other general purpose applications consisting of various discrete chips.

CH340 Driver for Windows, Mac and Linux

Install 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 ( 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.

UNO R3 (CH340) as a Cheaper Alternative to Arduino Uno

In today’s world, there are always alternatives to everything. In the Arduino world, if budget is not a constraint, you can always buy the official Arduino Development Boards. Of course, they are all expensive. For students, it is not practical to buy them. There are cheaper alternatives and one of them is the board that use CH340 USB to serial converter. The alternative for Arduino Uno R3 is the UNO R3 (CH340). Our price for the later is just P 350.00 compared to P 1,100.00 for the original one.

What is Arduino?

Arduino is an open-source electronics platform based on easy-to-use hardware and software. The platform is composed of a board (hardware) and a free software as the IDE (Integrated Development Environment) for writing and uploading your code. The most popular board is the Arduino Uno. If you’re just starting to learn microcontroller programming, you need to have an Arduino Uno.

If you don’t have an arduino uno yet, you can buy it HERE.
