We have CT-UNO, our version of Arduino UNO. Now this is special edition of CT-UNO and we called it Cytron UNO Special Edition.

CT UNO SE (Cytron UNO Special Edition)

CT UNO SE or Cytron UNO Special Edition Product of MALAYSIA http://www.cytron.com.my/

What is so special about Special Edition :) The SE comes with special side connectors. With these connectors, CT-UNO is able to be stack on TOP or Bottom of shield.

Anyway, here is CT-UNO vs Arduino UNO.

Basically CT-UNO-SE is Arduino UNO R3 with special side connectors. CT-UNO-SE is exactly the same as CT-UNO, except for the side connectors :)

The CT-UNO combines the simplicity of the UNO Optiboot bootloader (which load program faster), the stability of the FTDI and the R3 shield compatibility of the latest Arduino UNO R3.


  • SMD ATmega328 microcontroller with Optiboot (UNO) Bootloader.
  • USB Programming Facilitated by the Ubiquitous FTDI FT231X (more stable).
  • Input voltage: DC7-15V.
  • 1A (maximum) 5V voltage regulator.
  • 500mA (maximum) 3.3V voltage regulator.
  • 0-5V outputs with 3.3V compatible inputs.
  • 14 Digital I/O Pins (6 PWM outputs).
  • 6 Analog Inputs.
  • ISP 6-pin Header.
  • 32KByte Flash Memory.
  • SRAM: 2KByte
  • EEPROM: 1KByte
  • 16MHz Clock Speed.
  • R3 Shield Compatible.
  • TX, RX, Power, pin 13 LEDs are moved to edge.
  • Utilize USB Micro-B socket.
  • White PCB!
  • Special version of site connector (CT-UNO-SE only)



Is Ethernet Shield V2.0 (https://www.cytron.io/p-shield-ether-sd) compatible with Cytron UNO SE? ( Fadhli, 18/01/2018 )

I just bought a Cytron UNO SE last 2 days, when I wanted to burn a simple code inside and it was keep on downloading and won't be able to burn inside. Can I know what is the problem having on the board? Error message: avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0xf6 ( Leon, 07/04/2016 )

Hi, it is more convenient if you can post a topic in our technical forum with the snapshot of the error that you get and etc. as this session is only for short inquiry. Thanks. :)

Can we replaced the cytron uno with arduino uno for mobile robot control?. Will the project have effects if we use the arduino uno?. ( puteri, 04/04/2016 )

Hi. Yes it is possible. Cytron UNO has same functionality with Arduino UNO. Check this article for more info. Thanks. :)

I just bought cytron uno se and when i use it, my SMD turns very hot. Is it normal? ( Lim Huang Sheng, 11/03/2016 )

Hi. No. It is not normal. Can you provide more details about your project so that we can help you to troubleshoot the problem. You can post a topic in our technical forum as this session is only for short inquiry. Thanks. :)

Will you restock with promotion price (rm30)? If yes, anytime soon? Hope still can get the promotion price. ( Nazmi, 04/03/2016 )
