TechnoSam Arduino Uno R3 SMD Micro Controller Board Electronic Hobby Kit

Specifications Microcontroller: ATMEGA328P Power: 5V Recommended power: 7-12V Power limit: 6-20V Digital Pins (In/Out): 14 (6 with PWM) Analog inputs: 6 Maximum current per pin: 20mA Flash memory: 32KB SRAM: 2KB Clock: 16MHz CH340 Installation It is quite common for compatible Arduino boards to include the CH340 chip instead of the FT232RL that the original Arduino boards have. These chips are responsible for managing the USB interface of the board. Since these chips manage the communication between our Arduino and the PC, we must have the appropriate driver installed for them to work without problems. Compatible Arduino boards work correctly on some system versions and with some versions of the IDE. However, there are some system-IDE combinations where the original Arduino IDE is not able to communicate with our compatible Arduino board. To solve the problem we must download the CH340 driver from the manufacturer's website (WCH). Here are the download pages: Windows: http://www.wch.cn/download/CH341SER_EXE.html Mac: http://www.wch.cn/download/CH341SER_MAC_ZIP.html Linux: http://www.wch.cn/download/CH341SER_LINUX_ZIP.html To install it we will follow the following steps: 1. Connect the compatible Arduino board to the USB port. 2. Install the corresponding driver according to the operating system. 3. Reboot the system. 4.Open the Arduino ID and in the Tools menu select the appropriate Arduino board and the corresponding port. 5. Once the CH340 driver is installed, we should be able to communicate with our compatible Arduino board without problems.
