  • Product Code: CUTEDUINO
  • Warranty Period: 12 months
Have you ever wanted to use the small tiny Arduino for simple task like just human detection or to welcome a customer in your shop? Or maybe controller for RainbowBit only require 1 pin from Arduino? Now you can consider the CuteDuino. It is designed and produced base on DigiSpark. This is the lowest cost Arduino IDE programmable microcontroller board. No extra programmer or USB to UART chip is needed, just USB cable you are ready to program it with your favorite Arduino IDE :)

CuteDuino is designed based on ATtiny85, small chip but with a lot of power. ATTiny85 has 8KB of Flash, with the preloaded USB bootloader, around 6K of flash left for user. Comes with 5 I/O pins with PWM and ADC input too. It runs at 16MHz internal oscillator.

Well, we have modify the DigiSpark with breadboard friendly pin layout, higher current voltage regulator and on board Micro-B USB receptor. Most of Android phone uses Micro-B USB cable so you can utilize it. Of course CuteDuino is Arduino compatible, take it as 5 I/O (2 shared with USB) Arduino main board. There are several tutorials ready for you. not to forget the User's Manual.

  • ATtiny85 on-board, 8K of flash, 512 byte of SRAM, 512 bytes of EEPROM.
  • Internal oscillator runs at 16MHz.
  • USB bootloader so you can program it with the modified version Arduino IDE (from DigiSpark), or
  • With Cytron Arduino 3rd Party Boards URL, you can use the latest Arduino IDE.
  • Micro-B USB jack for power and/or USB uploading, you can put it in a box or tape it up and use any USB cable for when you want to reprogram.
  • Accorcding to DigiSpark, it is supported on All OS (Linux, Mac OS and Windows), yet we can only tested it on Windows.
  • ~6K bytes available for use (~2K taken for the bootloader).
  • On-board 5.0V voltage regulator with 800mA output capability and ultra-low dropout. Up to 15V input, thermal and current-limit protection.
  • Power with either USB or external output (such as a battery).
  • On-board green power LED and red pin #1 LED.
  • Reset button for entering the bootloader or restarting the program. No need to unplug/replug the board every time you want to reset or update!
  • 5 GPIO - 2 shared with the USB interface. The 3 independent IO pins have 1 analog input (ADC) and 2 PWM output as well. The 2 shared (USB) IO pins have 1 more analog inputs and aPWM output.
  • Hardware I2C / SPI capability for breakout & sensor interfacing.
  • Works with many basic Arduino libraries including RainbowBit library.
  • Comes with mounting holes.
  • Super small and Cute of course!
* Avoid using the shared IO (pin 3 and 4) during program loading as it may affect the USB communication.

Getting Started with CuteDuino:

Does it include header pin while purchase? ( CCL, 02/11/2019 )
Hi, yes it comes together as shown in the picture. Thanks :)
why does cuteduino makes red led dim and ligth up? ( Blazejlo, 27/08/2019 )
Hi, can you explain in details by email your question to
my cuteduino connect and disconnect every 5 seconds and my computer (windows 7) says its unknown device ( Blazejlo, 28/07/2019 )
Hi, you may email all the related step that you make to
is it compatible with windows 7 ( blazejlo , 08/07/2019 )
Hi, sorry we can't verify that since we don't have any computer running Windows 7. Thanks.
mam problem z cuteduino.
chce zaprogramować go ale cały czas albo się odłącza albo pisze unkwon device ( korzystałem z instrukcji )
jak można temu zaradzić?
( Blazejlo, 05/04/2019 )
Hi, sorry we only understand English. If you have any problem with this product you may email to .
What are the dimensions of the Cuteduino? ( Joshua, 21/09/2016 )


The dimension of the board is 42mm x 15mm.

If you have further question, you can ask at our technical forum, as this session is only for short inquiry. Thanks. smiley??

Does the Cuteduino support keyboard or other HID devices emulation, e.g. mouse? ( Marcus, 09/06/2016 )

Hi. Yes it does support. Thanks :)

Is this board have analog input?? ( Eawan, 07/03/2016 )

Hi, It does has analog input. You can refer to the pinout diagram. Thanks. :)

Hai.. Can i use this board with RF transmitter and receiver module to control vibrator motor (usually use in phone) wirelessly. Can you advice me? ( Samsul, 16/12/2015 )

Hi. It is possible to do so. For further inquiry, kindly visit our technical forum as this session is only for short inquiry. Thanks. :)

Does Cuteduino have input,tx and rx pins? ( Azriel, 19/06/2015 )

There is no hardware UART, but you can utilize SoftSerial.h and TinyChangePin.h to utilize any IO for serial communication. Please come to our technical forum for further discussion as this section is for short inquiry, thanks :)
