More info


SparkFun BlackBoard is a base plate compatible with Arduino. Similarly to Arduino Uno, the board has an ATmega 328P microcontroller, the terminal layout is compatible with Arduino UNO, thanks to which shield extensions can be used. The PCB uses the CH340G chip for communication with the computer. The user has 14 GPIO ports (inputs / outputs), of which 6 can generate PWM signal. The board also has 6 analogue inputs and an ISP connector for programming using a programmer. The PCB also includes a Qwiic standard connector that allows easy connection of modules / sensors, which also have a connector that complies with this standard. SparkFun BlackBoard can be supplied with 7 ... 15 V voltage using a DC connector.
