Product details of UNO R3 Development Board (ATmega328p and CH340) + 50cm Cable Overview: Ideal board for creative projects in the field of electronics. It uses the ATmega328P microcontroller and the CH340 Serial USB converter. The product includes a 50cm cable. Technical Specifications: • Operating voltage: 5 V; • Jack supply voltage: 7-12 V; • I / O pins: 14; • PWM pins: 6 (out of 14 I / O); • Pini ADC: 8; • Flash memory: 32 kB (8 occupied by bootloader); • TWI, SPI and UART communication; • Operating frequency: 16 MHz. This development board can be the basis of many electronics projects. In combination with other devices, such as sensors and shields of Ethernet or Bluetooth, you can design innovative installations that can automate your home. The difference from the original Arduino Uno board is the package in which the ATmega328p microcontroller is located and the fact that it is programmed using the CH340 integrated circuit. Remember to install the driver for the CH340 CIP before use. To be able to program the board for other examples: Download Arduino IDE . Don't delay, buy today. Add to cart now!
