RobotZero is one of TinyCircuits' second generation processor boards, adding performance upgrades and additional features to the original TinyDuino including (4) Whisker connectors, (2) motor ports, (4) servo ports, and a built in 9-Axis sensor. RobotZero 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 30x30mm board. We've kept our standard TinyShield expansion port, allowing for use with our current shields.

Main Features:

Atmel SAMD21 processor (same as is used on the Arduino Zero)
More memory compared to TinyDuino (both Flash and RAM)
TinyShield expansion connector, built in micro USB connection
Power switch, regulator, lithium battery management on board
Precision clock crystal and Real Time Clock hardware built in, low power standby
Populated 9-Axis Sensor: 3D accelerometer, 3D gyroscope, and 3D magnetometer
(4) Whisker Ports
(2) Motor Ports
(4) Servo Ports
Up to 10 ADC inputs, up to 10 PWM outputs, up to 16 external interrupts

NOTES:

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 TinyZero and now it does not respond, you may need to force this into bootloader mode. To do this, power off the TinyZero using the slide switch. Plug the USB cable into the TinyZero and your computer. Then press and hold the button on the bottom on the TinyZero while sliding the switch to the ON position. Then try uploading your program to the TinyZero 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
