Maker UNO – Arduino UNO Compatible Board, Developed to Learn Coding and Microcontroller
We bring you the Maker-UNO, An Arduino UNO compatible board designed and developed especially for students to learn coding and microcontroller. We named it Maker UNO to encourage everyone to be a maker by getting started with this fantastic board. Oh! BTW, it is PURPLE color.
We have removed the DC jack (12V adapter input), and the 5V linear regulator as 90% of the beginners and projects only use 5V from USB. So the board can be offered at a more affordable price. But don’t get us wrong, Maker-UNO is not removing components; we design more components to help everyone learn programming, coding, and microcontroller. For example, we added a piezo buzzer that will act as simple audio output; of course, you can program it. Yet, to ensure the compatibility of Arduino UNO, we also have 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 has a programmable LED on every digital pin, from pin D0 to D13.
That is a lot of LEDs. We believe LEDs provide excellent visual/light digital output where the eyes can observe, while the piezo buzzer offers sound feedback where the ears can hear. That is good enough for outputs; how about input? We reserved the reset button and added a programmable button. 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 regular USB to UART IC.
Maker-UNO combines the simplicity of the UNO Optiboot bootloader (which loads the program faster), the stability of the CH340, and the R3 shield compatibility of the latest Arduino UNO R3. Of course, we preserve the excellent feature on CT-UNO, the USB MicroB socket for program loading and to power the board. This enables everyone to utilize the USB cable of the Android smartphone and power bank. The program can be loaded from your computer by utilizing 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 fantastic features Arduino UNO has been offered. 14 Digital I/O pins with 6 PWM pins, 6 Analog inputs, UART, SPI, external interrupts, not to forget the I2C too. The SDA, SCL, and IOREF pins which are being broken out on UNO R3, are on CT-UNO too. We have also populated the ISP header pins (SPI and power). With this, Maker-UNO will be compatible with all Arduino UNO shields.
