1. INTRODUCTION
CuteDuino is an Attiny85 based microcontroller development board similar to the Arduino
line, only cheaper, smaller, and a bit less powerful. With a compact yet powerful Attiny85
microcontroller and the ability to use the familiar Arduino IDE, the CuteDuino is a great way
to jump into electronics, or perfect for when an Arduino is too big or too much.
It is inspired and build around the DigiSpark which uses the micronucleus bootloader.
CuteDuino comes with direct USB connection which allows it to be programmed directly
over a bit banged USB connection. Yup, no USB to UART bridge in between. Besides, the
CuteDuino can also be used to emulate any USB 1.0 device!
The board is broken down into 10 individual pins and has 2 indication LEDs: Power and
active high LED connected to pin 1 (arduino designation). It has 5 GPIO pins but two are
shared with the USB interface. The other three pins have one analog input and two PWM
outputs. The shared pins (USB) have an extra analog pin and a PWM pin which can be used
if your board does not need to be USB connected to the computer after programming. This
version runs on 5.0V and has an onboard voltage regulator so you can also run on a 12V
supplied to the "VIN" pin. With the new Arduino IDE (v1.6.4 and above), you can install all
the necessary library and example with simple import, please follow this tutorial.
CuteDuino come with this features:
●Inspired by Digispark.
●With the new Arduino IDE v1.6.4, we have prepared the board manager URL, install
CuteDuino accordingly with this tutorial.
●Power via USB or external power (7 - 12V).
●On board 5V 800mA (Max 1A) voltage regulator.
●Pre-built with micro USB receptor.
●5 I/O pins (2 I/O shared with USB).
●2 ADC, analog input pin (pin 2 = A1, pin 4 = A2), A2 shared with USB.
●3 PWM output pin (pin 0, 1 and 4), pin 4 shared with USB.
●8K flash/program memory (~6k after bootloader).
●512 bytes of SRAM.
●512 bytes of EEPROM.
●ATtiny85 running at 16 MHz (Internal oscillator).

7. GETTING STARTED
This section will guide user to get started with CuteDuino. There are two parts which are
“Installing CuteDuino USB Driver” and “Program CuteDuino with Arduino IDE”. For
further information can refer to this link.
7.1 Installing CuteDuino USB Driver
Download the Digispark package which include the open source Arduino IDE (v1.5.8C)
Digispark Addons and Digispark driver. Double click the files to execute it. It will extract the
necessary files and install the USB driver. Easy!
Alternatively, if you want to download the driver only, please download from CuteDuino
Github folder. Extract to the zip file.
1. DigisparkWindowsDriver
Using Micro-B USB cable, connect CuteDuino to computer. Once connected, the PWR LED
will turn ON.

Product User’s Manual – CuteDuino
Windows Security will popup, choose Install driver software anyway. Reminder, for
Windows 8 user, if driver signature enforcement is not disable, Windows Security will not
popup and driver installation will not succeed.
Windows has successfully updated your driver software.
