KEYESTUDIO Development Board ATmega328P for Arduino UNO with USB Cable

Description: It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it via an external DC power jack (DC 7-12V) or via female headers Vin/ GND(DC 7-12V) to get started. TECH SPECS Microcontroller: ATmega328P-PU Operating Voltage5V Input Voltage (recommended): DC7-12V Digital I/O Pins:14 (D0-D13)(of which 6 provide PWM output) PWM Digital I/O Pins: 6 (D3, D5, D6, D9, D10, D11) Analog Input Pins: 6 (A0-A5) DC Current per I/O Pin: 20mA DC Current for 3.3V Pin: 50mA Flash Memory: 32 KB (ATmega328) of which 0.5 KB used by bootloader SRAM: 2KB (ATmega328P-PU) EEPROM: 1KB (ATmega328P-PU) Clock Speed: 16MHz LED_BUILTIND: 13 Specialized Functions of Some Pins Serial communication: Digital pins 0 (RX) and 1 (TX). PWM Interfaces (Pulse-Width Modulation): D3, D5, D6, D9, D10, D11 External Interrupts: D2 (interrupt 0) and D3 (interrupt 1). These pins can be configured to trigger an interrupt on a low value, a rising or falling edge, or a change in value. SPI communication: D10 (SS), D11 (MOSI), D12 (MISO), D13 (SCK). These pins support SPI communication using the SPI library. IIC communication: A4 (SDA); A5(SCL) The package contains: 1 x KEYESTUDIO Development Board for Arduino R3 Board 1 x USB cable
