  • Quickly see the logic state of any GPIO pin with bright red and green LEDs - even pulses as short as 1mS can be seen!

  • Rapidly prototype with the included breadboard!

  • Easily dig deeper by connecting test equipment to any GPIO pin, the breakout headers make it easy!  You can connect:

    • A DMM to measure voltages

    • An oscilloscope to view waveforms

    • A protocol analyzer to decode SPI/I2C/UART communications

    • A function generator to drive signals into the circuit

    • A counter/timer to measure timing
