Meet the components

Me Auriga


Me Auriga is the updated version of Orion and is equipped with multiple on-board sensors for temperature and sound intensity, a gyroscope, and a buzzer driver. It features a one-key power switch, wireless Bluetooth control and firmware upgrade capability. The original two red ports have been updated to four ports with the same functions. Port 5 is isolated only with serial communication function, so it cannot be used to update a program but only for communication. It is also compatible with USB serial ports. Ports 6-10 are compatible with dual digital, analog, I²C bus, unibus, and analog serial ports. Me Auriga has an encoder motor port, a smart servo port and an LED Ring Light Panel port (with a power switch). The size of PCB is also enlarged.

For more information, see About Me Auriga.

Me Ultrasonic Sensor

Me Ultrasonic Sensor is an electronic module designed for distance detection. The distance range it can detect is 3–400 cm. mBot Ranger can use this module to avoid obstacles or for other programs about distance detection. The yellow tag on the interface of this module indicates that it is a single digital interface and that it should be connected to a port with the yellow tag on the main control board.

For more information, see About Me Ultrasonic Sensor (for mBot Ranger).

Me Line Follower

Me Line Follower is designed for line-following robots. There are two sensors, each with an IR transmitting LED and an IR static induction phototransistor. mBot Ranger can move along a black line on a white background or a white line on a black background. It features fast detection and simple circuits. The blue tag on the interface of this module indicates that it is a dual digital interface and that it should be connected to a port with the blue tag on the main control board.

Photoelectric Encoder Motor 180 RPM


The Photoelectric Encoder Motor 180 RPM is equipped with an optical encoder that enables high-accuracy control. With two M4 threaded holes on each of the three sides, it can be easily connected to Makeblock mechanical parts and thus can be used flexibly in combination with other parts. The customized material it uses reduces noise and promises large output torque. It supports multiple motor drivers and main control boards, such as Orion, MegaPi, MegaPi Pro, and Me Auriga.
