Description

Durian is the most popular fruit in Malaysia. Although it is full of thorn-covered rind, its content I am sure will amaze you. So, same with Durian Uno, it is covered with thorns and the function will also surprise you.

        

 

 

Hardware benefits

  1. Durian UNO's wide range of input power supply (DC 3.7V to 12V) makes it easy to attach different types of batteries such as AAx4, single 18650 Li-ion battery, and so on. While Arduino UNO will be unstable if the input power supply is less than DC 7V.

  1. We have increased the VCC and GND pin on Durian Uno which is user-friendly to connect the module without breadboard while Arduino UNO does.  Besides, Durian UNO makes servo motor plug and play directly. The DC current for 5V (VCC) up to 1A which able to drive 6 pieces of SG90 micro servo motor simultaneously and a MG995 servo motor without causing stability problem.

 

3.Based on our experience, above 80% of projects involve output such as DC water pump, DC motor, DC stepper motor, and else. Therefore, we had a built-in L298P motor driver on Durian Uno to make it easy to attach the DC motor, and water pump without experiencing messy wiring. 

      

Besides, Durian Uno is able to run the 4 loads with 2 different voltages (by controlling the PWM in ENA and ENB) without adding extra components.                

     

4.Durian Uno had built in the melody buzzer.

5.Durian Uno also provides the slot for Wi-Fi module, ESP8266, and Bluetooth module, HC-06.

      

6.Durian Uno had built in the ultra-sonic sensor connector and I2C connector to let users more convenience in connecting the ultrasonic sensor to the Durian Uno.

     

7. Durian Uno uses Type-C USB interface, Type-C cable is common and easy to get. It can more convenient to connect Durian Uno with the computer.

Durian Uno IoT Benefits

 

ESP8266 Wi-Fi Module & Durian Uno

  1. Durian Uno + ESP8266 Wi-Fi module (with Durian Blynk Firmware) is a dual-core processor that can work simultaneously in the same circuit. Both devices are working standalone.
    • Durian Uno as a control unit to control input/output pins.
    • with build in Durian Blynk Firmware, ESP8266 Wi-Fi module works as receive and transmit data to Blynk.

                  

Blynk code

To maintain the internet connection, Blynk runs some code in the background. Some of the code such as while loop function, delay function and else may interrupt the background process subsequently cause error. Durian Uno + ESP8266 Wi-Fi module (with Durian Blynk Firmware) overcome this problem as the Durian UNO and ESP8266 Wi-Fi module work independently. The code will upload into Durian UNO and it won't effect the process inside ESP8266 Wi-Fi module (with Durian Blynk Firmware). Therefore, the IOT project runs smoothly with Durian UNO + ESP8266 Wi-Fi module (with Durian Blynk Firmware).

  1. With the library of Durian Blynk ESP8266, Durian Uno works prefer with ESP8266 Wi-Fi module in IOT.
  2. With help of Durian Blynk ESP8266 Library, the code is easy to understand, and code troubleshooting becomes easy. 

 

 

Problem IoT Project when using ESP series controller and Solution with Durian UNO

  1. Most of the sensors and modules use 5V as operating voltage, when using the ESP32/ESP8266 as the main controller, the extra logic converter is needed since the ESP32 / ESP8266 are using 3.3 V as operating voltage. For example, MQ series gas sensor is connected with ESP series controller and the gas sensor's operating voltage is 5V. It will effect the accuracy of reading data. There's another example, l298 motor driver with ESP series controller. The 3.3V operating voltage as a PWM signal makes the motor driver unable to maxima the output as the 5V PWM is the signal to drive maximum output.
    Durian UNO's 5V operating voltage make it compatible with most of the sensors and modules. 

  2. Most of the libraries are not yet completely compatible with the ESP series controller. Besides, the debugging of the library's issue is taking time. Therefore, those beginners who get started with IoT projects will get into trouble and perhaps will lose confidence in their project.
    Durian Uno is compatible with the majority of sensor libraries and with the help of Durian Blynk ESP8266 library makes it easy to use and user-friendly. Durian UNO definitely builds the beginner's confidence and generates more interest in IoT projects. The great engineer will be born soon! 

  3. The while loop, delay function for the ESP series controller may cause error when using it for IOT project. 
    Durian UNO and ESP8266 Wi-Fi module work independently. The while loop, delay function free to use without causing error in IOT project.
