User Manual

Use 5V DC (4V to 5.5VDC range works) with positive-center voltage. If you try to plug in a negative-center power

supply, the polarity-protection will kick in and you will not see any lights on the Crickit.

The Crickit uses a power management chip to keep you from accidentally powering it from 9V or 12V, damaging your

electronics. Look for the OK and /!\ warning LEDs. If you see the green OK LED, the power is fine! If you see the red

warning LED, the voltage is too low, too high, or too much current is being used.

You can turn off the Crickit at any time with the On/Off switch. This will turn off the 5V power, completely disabling all

motors, as well as turning off the seesaw control chip.

There's also a Reset button. This button will reset the seesaw chip, and can be used to load new seesaw firmware (you

won't likely have to do that). On the Feather Crickit, this button

also

connects to the Feather reset pin. On the Circuit

Playground Crickit, it

does not

connect to the Playground Reset button.

On the Feather Crickit only, if you double-click the Feather reset button to load new firmware, such as a new version of

CircuitPython, the Crickit will also go into double-click firmware-update mode. After you load the new firmware on the

Feather, wait for the firmware to start up, and then click the reset button again, once, to get the Crickit back into

regular operation mode.

Power options to consider:

3 x AA Battery Holder (https://adafru.it/BzH) with On/Off Switch (needs JST to 5.5/2.1 adapters)

Wall power supply (https://adafru.it/BzI) - 5V, 2A, US

And more options in the https://www.adafruit.com/categories (https://adafru.it/BzC)!

4 x Hobby Servos

Hobby servos are

really

popular in robotics because

they're fairly low cost, very easy to use, and reliable.
