![]() ![]() 7V 12V (recommended) Clock Speed, 16 MHz Flash Memory, 32 KB (2 KB. If this is your first experience tinkering with the platform, the UNO is the most robust board you can start playing with. Technical Specifications of Arduino UNO Input Voltage. ![]() The UNO is the best board to get started with electronics and coding. Instead, it features the Atmega16U2 programmed as a USB-to-serial converter. The Uno R3 differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. ATmega328P (for Arduino UNO R3) or Microchip ATmega4809 (for Arduino UNO. Arduino Uno Rev3 is a microcontroller board based on the ATmega328P, an 8-bit microcontroller with 32KB of Flash memory and 2KB of RAM. Note that the two ICSP headers are separately used to program the firmware to ATMEGA16U2-MU and ATMEGA328P-PU, but generally the two chips have been programmed well. Dimensions Adafruit Metro / Arduino UNO form factor Camera connector and M. The SparkFun RedBoard combines the simplicity of the UNOs Optiboot bootloader, the stability of the FTDI, and the shield compatibility of the Arduino R3. ![]() It contains everything needed to support the microcontroller simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. It has 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, 2 ICSP headers and a reset button. supply power to board through the MicroUSB connector or DC-jack voltage regulator (LDO) can accept incoming voltage from 6V to 12V DC. In addition, this chip contains 32 kilobytes of SRAM and 256 kilobytes of flash. A Renesas RA4M1 32-bit Arm Cortex-M4 microcontroller (MCU) running at 48 MHz powers the R4. Keyestudio Uno R3 is a microcontroller board based on the ATmega328 (datasheet), fully compatible with ARDUINO UNO REV3. Fortunately for shield compatibility, the UNO R4 continues with the same physical form factor. ![]()
