Arduino UNO R3 Development Board with CP2102 – Compatible Model High Quality

The Uno R3 CP2102 ATmega328P Development Board serves as a cost-effective alternative to the official Arduino Uno R3, replacing the ATmega16U2 with the CP2102 USB-to-serial chip for reliable PC connectivity.​

Key Specifications

This board uses the ATmega328P microcontroller running at 16 MHz, with 32 KB flash memory (including bootloader), 2 KB SRAM, and 1 KB EEPROM. It provides 14 digital I/O pins (6 PWM-capable), 6 analog inputs, UART/I2C/SPI support, a USB-B port, DC jack (7-12V recommended), and ICSP header.​

Power and Dimensions

Operating at 5V with up to 20 mA per I/O pin, it supports USB or external power sources. Physical size measures 68.58 mm long by 53.34 mm wide.​

Usage Notes

Compatible with Arduino IDE after installing CP2102 drivers, it’s ideal for prototyping in automation projects like sensor integration or motor control, given your background in PLCs and Arduino programming. Connect via USB for immediate programming or power independently for standalone operation
