ATMEGA328P microcontroller development board, Arduino-compatible R3 PLUS MCU development board
based on ATMEGA328P-AU
Operating voltage 5V/3.3V. Dual voltage level to support more shields
Reset Lateral. Lateral button is easier to use when connecting with shield
Bootloader switch Yes. The board can be configured to run program immediately when power-up by the switch
USB connector Micro USB. Micro connector is more commonly used, and shields won't be blocked anymore while connecting
DC jack Low profile. Shields won't be blocked anymore while connecting
Power output header Yes. Providing 5V/3.3V power output OR common-grounding with other boards
3.3V power output 800mA Max. R3 PLUS features higher driving capability
Oscillator Crystal oscillator. suit for applications where accurate clock reference is required
ADC channel 8. CFG used as ADC6 by configuration, and ADC7 from the Reserved PIN
USB driver Compatible with all main systems. Driver will never failed to install thanks to the onboard FT232
Firmware fixing Supported. Firmware can be fixed by using the onboard FT232, no extra programmer is needed Connecting with Waveshare Shields
