Product Description
The UNO R3 CH340 is a microcontroller board based on the ATmega328P, designed for beginners and advanced users in the field of electronics and programming. It is a clone of the popular Arduino UNO R3 but uses the CH340 USB-to-serial converter chip, making it more cost-effective. The board features 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header, and a reset button.
Key features of the UNO R3 CH340 include:
- Microcontroller: ATmega328P
- Operating Voltage: 5V
- Input Voltage (recommended): 7-12V
- Input Voltage (limit): 6-20V
- Digital I/O Pins: 14 (6 provide PWM output)
- Analog Input Pins: 6
- DC Current per I/O Pin: 20 mA
- Flash Memory: 32 KB (ATmega328P) of which 0.5 KB used by the bootloader
- SRAM: 2 KB (ATmega328P)
- EEPROM: 1 KB (ATmega328P)
- Clock Speed: 16 MHz
- USB-to-Serial Chip: CH340G
The board is compatible with the Arduino IDE, making it easy to program and integrate into various projects. It supports both Windows and Mac operating systems, though additional drivers may be required for the CH340 chip. The UNO R3 CH340 is widely used in educational settings, DIY projects, and prototyping due to its versatility, ease of use, and affordability.
