Whisker Kickstarter Item

Note: This item is currently only available on Kickstarter, it will be for sale on our site after the Kickstarter is complete and rewards have been fullfilled


WhiskerZero is one of TinyCircuits' second generation processor boards, specifically designed for low-cost Whisker projects. WhiskerZero is based on the Atmel SAMD21 32-bit ARM Cortex M0+ processor (the same one used in the Arduino Zero) and provides a USB connectivity port, power management and battery charger in a single 15x32mm board. Note: The battery is not included and is sold separately. 

    Main Features:

    • Atmel SAMD21 processor (same as is used on the Arduino Zero)
    • More memory compared to TinyDuino (both Flash and RAM)
    • Power switch, regulator, lithium battery management on board
    • Precision clock crystal and Real Time Clock hardware built in, low power standby
    • 4 individually addressable I2C Whisker Ports

      • Atmel ATSAMD21G18A 32 bit ARM processor at 48MHz, Arduino Zero compatible
      • 32.728KHz clock crystal, RTC hardware built in with standby mode down to 0.2mA
      • Ultra compact size and weight (smaller than a US Quarter!)
        • 15mm x 32mm (.59 inches x 1.26 inches)
        • Max Height: 4.6mm (0.18 inches)
        • Ultra-thin 0.61mm (0.024 inches) PCB
        • Weight: 1.40 grams (0.049 ounces)
      • Atmel 32-bit ATSAMD21G18A ARM Microcontroller
        • ARM Cortex M0
        • 256KB Flash, 32KB SRAM
        • 12-bit ADC, 10-bit DAC
        • Default Clock speed: 48MHz
      • 2.7V – 5.5V operating voltage with built in 3.3V regulator
      • Arduino compatible bootloader with CDC Serial port, plug and play on OSX and Windows 10
      • 4 individually addressable I2C Whisker Ports 


      • This processor board is designed for low-cost Whisker projects, so this board does not include the TinyShield expansion connector.
      • To send text to the Arduino IDE Serial Monitor, use the SerialUSB object instead of Serial
      • If you were able to upload a sketch to the WhiskerZero and now it does not respond, you may need to force this into bootloader mode. To do this, power off the WhiskerZero using the slide switch. Plug the USB cable into the WhiskerZero and your computer. Then press and hold the button on the bottom on the WhiskerZero while sliding the switch to the ON position. Then try uploading your program to the WhiskerZero and it should work. You may need to try this several times if it does not work the first time.
      • All batteries are sold separately
