1. INTRODUCTION
We bring you the Maker UNO, an Arduino UNO compable board designed and developed
specially for students to learn coding and microcontroller. We named it Maker UNO to
encourage everyone to be a maker by geng started with this amazing board. By the way, it
is in PURPLE !
3 years ago, we re-engineered Arduino UNO and introduce CT-UNO . It has been used in
many projects development, among students, engineers, teachers, and makers. We have
also been conducng training using CT-UNO for several years, and from the observaons and
feedback gathered; there are some features are under-ulized, yet there are some features
which are needed for beginner. Working hand in hand with ARUS and rero team, we iniate
the redesign of CT-UNO, making it more affordable, and more beginner friendly. It is Arduino
UNO R3 compable, and by that, Maker UNO can be programmed via Arduino IDE and
compable with all the example code and libraries for Arduino UNO.
“We named it Maker UNO to encourage everyone to be a maker
by getting started with this amazing board!”
We have removed the DC jack (12V adapter input) and the 5V linear regulator as 90% of the
beginner and projects use 5V from USB only. so the board can be offered at more affordable
price. But don't get us wrong, Maker-UNO is not removing components, we actually
design-in more components to help everyone to learn programming, coding and
microcontroller. We added a piezo buzzer that will act as simple audio output, of course you
can program it. Yet, to ensure the compability of Arduino UNO, we have also added a slide
switch to disable this piezo buzzer and leave the IO as it is. Aside from the standard LED on
pin 13, Maker-UNO comes with a programmable LED on every digital pin, from pin D0 to D13
:) That is a lot of LEDs. We believe LEDs provide very good visual/light digital output where
the eyes can observe, while piezo buzzer offers sound feedback where the ears can hear.
That is good enough for outputs, how about input? We reserve the reset buon and added a
programmable push buon. How good is that? Now you can learn digital input, output,
PWM (piezo buzzer and LED brightness) with just the Maker-UNO board.

Not to forget the change of FTDI chip to CH340 IC, the low cost yet stable USB to UART IC.
Maker-UNO combines the simplicity of the UNO Opboot bootloader (which load program
faster), the stability of the CH340 and the R3 shield compability of the latest Arduino UNO
R3 .
Of course, we preserve the good feature of CT-UNO, the USB Micro B socket for program
loading and to power the board. This enable everyone to ulize the USB cable of Android
smart phone and power bank. Program can be loaded from your computer by ulizing your
Android phone USB cable. Select "Arduino/Genuino UNO" for the "Board" in Arduino IDE
and choose the correct COM port, you are ready to upload the code. If you do not have the
Micro-B USB cable , please get it as it is sold separately.
Maker-UNO has all the amazing features Arduino UNO has to offer, 14 Digital I/O pins with 6
PWM pins, 6 Analog inputs, UART, SPI, external interrupts, not to forget the I
2
C too. The SDA,
SCL and IOREF pins which being broken out on UNO R3 are on MAKER-UNO too. We has also
populated the ISP header pins (SPI and power). With this, Maker-UNO will be compable
with all Arduino UNO shield.
Features:
●SMD ATmega328P microcontroller(the same microcontroller on Arduino UNO) with
Opboot (UNO) Bootloader.
●USB Programming facilitated by the CH340.
●Input voltage: USB 5V, from computer, power bank or standard USB adapter.
●500mA (maximum) 3.3V voltage regulator.

●On board programmable push buon (pin 2, need to configure as INPUT_PULLUP).
●On board piezo buzzer (pin 8).
●Ulize USB Micro-B socket.
●PURPLE PCB !

5.2 Using Arduino Uno Shield
Since Maker-UNO doesn’t have Vin, any Arduino shield that require Vin is not compable.
However, if the shield have opon to choose power source (either Vin or external voltage), it
can be used with Maker Uno (by using external voltage). For example:
●Cytron 3A Motor Driver Shield
●Cytron G15 Shield
●Cytron 10A Motor Driver Shield
●Etc…
The rest, it is fully compable with Maker Uno. For example:
●LCD keypad Shield
●Cytron XBee Shield
●Cytron SKM53 GPS Shield
●Etc…
So which Arduino shield is not compable with Maker Uno? Below is the example of shield
that need Vin and it don’t have opon to select power source.
●GPRS Shield V3.0
●Etc...
NOTE
How do I know either the shield is working with my Maker Uno?
You can refer to the product’s schematic (Arduino shield) and check for the Vin connection.
For further questions, please visit to our technical forum for similar question or post your
question there.

CAUTIONS
What is the differences if I just select Arduino/Genuino Uno instead of Maker UNO?
Arduino/Genuino Uno by default will set all IO pins to INPUT. If you upload a Blink example
to Maker UNO, you will get LED 13 blink and also other LEDs light up randomly,
(somemes all LED turns on). This is because INPUT is floang, as long as you don’t set
those pins to OUTPUT or connect to external circuit, it will produce a floang voltage (can
be 1V, 2V or any voltage in range of 0-5V). This floang voltage somemes is enough to
light up the LED. Actually this is not a problem, just making confusion for newbie/beginner
to start learning using Maker UNO.
We create a custom board package for Maker UNO to cater this confusion. What Maker
UNO board package do is to inialize all digital IO pins to OUTPUT by default. So when you
upload Blink example, only pin 13 will blink, other pins will remain off. This approach is
good for newbie/beginner, HOWEVER we advise to use this method only for early lesson.
Once you already understood regarding INPUT and OUTPUT, we advise you to select
Arduino/Genuino Uno as a board for safety purpose.
