Product Details
ATmega328 microcontroller with Optiboot (UNO) Bootloader. Rev3 shield compatible.
Program with a USB Micro-B cable using the Arduino IDE platform: Plug in the board, select “Arduino UNO” and you’re ready to upload code
Hardware peripherals you know and love: 20 Digital I/O pins with 6 PWM pins, 6 Analog Inputs, UART, SPI and external interrupts
Broken out the SDA, SCL and IOREF pins, so it will be compatible with future shields Power over USB or through the barrel jack 7 to 15VDC
The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.
