    ATtiny3217 microcontroller. The voltage limits configured in the on-board debugger on ATtiny3217 Curiosity Nano are 1.8-5.5V. Info:  The target voltage is set to 3.3V when the board is manufactured. It can be changed through MPLAB X IDE project properties and in the Atmel Studio device programming dialog.

  • Page 15: External Supply

    3.3.2 External Supply ATtiny3217 Curiosity Nano can be powered by an external voltage instead of the on-board target regulator. When the Voltage Off (VOFF) pin is shorted to ground (GND), the on-board debugger firmware disables the target regulator, and it is safe to apply an external voltage to the VTG pin.

  • Page 16: Vbus Output Pin

    VBUS Output Pin ATtiny3217 Curiosity Nano has a VBUS output pin that can be used to power external components that need a 5V supply. The VBUS output pin has a PTC fuse to protect the USB against short circuits. A side effect of the PTC fuse is a voltage drop on the VBUS output with higher current loads.
