1 Introduction
Makeblock Orion is an easy-to-use mainboard based on Arduino Uno with improvements for education. It provides eight RJ25 ports to connect to all the other Me series modules with color-labels, can save you from horrible pin-wiring and help you focus on inventor amazing projects. Makeblock Orion supports most of programming software (Arduino / Scratch / ), and we offer the customized graphical programming software (Scratch for Robot / Makeblock App).
2 Features
- 100% Arduino compatible;
- Comes with Arduino library for easy programming;
- Support Scratch For Robot, cover all ages people;
- Using RJ25 cable connect the Me series electronic modules, super easy to wiring;
- Modular installation, and compatible with LEGO Bricks;
- Two-channel motor driver integrated (Two channels additional with Me-motor driver through PORT_1&2);
3 Parameters
Operating Voltage: 6-12V DC power;
Microcontroller: ATmega238;
Detecting Angle: prefer at 30 degree angle;
Dimension: 80 x 60 x 18 mm (Length x Width x Height);
4 Interface Description
There’re 8 RJ25 connectors in total. The tags on the connectors have 6 types of color. Check the following table for the function and attribute of each connector.
table 1 : The function of each tag color
Yellow, blue, gray, black, purple and white represent the output voltage of Vcc (5VDC), which is the Stable output voltage. Generally, it is connected to some voltage driver module with 5V.

5 Usage
- Connect the Makeblock Orion and computer with micro-USB cable first. The first time you use Makeblock Orion ,you need to install the USB interface driver.
-
Makeblock Orion support up-computer and mobile device control.(Arduino IDE/Scratch For Robot/Makeblock App control).

6 Programming Guide
1. Here’s an example to show you how to programming the buzzer of Orion in Arduino IDE:
A) Connect the Makeblock Orion and computer with micro-USB cable first.
B) Create a file in Aduino IDE, and write the buzzer control sketch as follow:
- #include
- #include
- #include
-
- void setup()
- {
- }
-
- void loop()
- {
- buzzerOn(); //turn on the buzzer
- delay(50); // wait 50 milliseconds
- buzzerOff(); //turn off the buzzer
- delay(50);
- }
If you got any error information, please check if there is a grammar mistake in your code.
C) Upload the program
D) After the uploading is successful, the buzzer will sound. If it doesn’t work, please check if the buzzer switch on the board is TURN ON.
2. Here’s an example to show you how to programming Me 130 DC Motor in Arduino IDE
A) Connect the Makeblock Orion and computer with micro-USB cable first.
B) Connect the Makeblock Orion and Me 130 DC Motor as below:
C) Create a file in Aduino IDE, and write the buzzer control sketch as follow:
- #include
- #include
- #include
-
- MeDCMotor motor1(M1); //130 DC Motor can connect to the motor interface(M1 or M2)
-
- uint8_t motorSpeed = 100; // value: between -255 and 255.
-
- void setup()
- {
-
- }
-
- void loop()
- {
- motor1.run(motorSpeed);
- delay(2000);
- motor1.stop();
- delay(100);
- motor1.run(-motorSpeed);
- delay(2000);
- motor1.stop();
- delay(100);
- }
If you got any error information, please check if there is a grammar mistake in your code.
D) Upload the program
E) After the uploading is successful, you can see the motor rotating in clockwise direction 2s, pause 100ms, rotating in anticlockwise direction 2s, pause 100ms.
3. Other Demo Code
There are some demo code of the Me series electronic modules from the File > Examples > MakeBlockDrive. You can use the demo code from Makeblock Library New or Makeblock Library Old to get started play the Me series electronic modules. We recommend that you use the latest code to get our best service support.
7 Power supply
Kindly advise to power the board by connecting 6V-12VDC to DC Connector of Makeblock Orion. Otherwise it will power off for PORT 1 and 2. There’s a switch on the board for controlling the power ON/OFF.
