Introduction

ELECFREKAS Motor:bit is a kind of motor drive board based on micro:bit. It has integrated a motor drive chip TB6612, which can drive two DC motors with 1.2A max single channel current. Motor:bit has integrated Octopus series' sensor connectors. You can plug various sensors into it directly. Among these connectors, P0, P3-P7, P9-P10 support sensors with 3.3V power voltage only; P13-P16, P19-P20 support 3.3V or 5V sensors. You can change electric level by sliding the switch on the board.

Detailed Introduction Of Some Connectors:

1. VCC Switch-3.3V/5V electric level switch.
Slide switch to the end of 5V, the electric level of the blue pins (P13,P14,P15,P16,P19,on motor:bit is 5V, and the voltage of the red power pins is 5V too. Similarly, when slide switch to 3.3V, the voltage of blue pins and red pins are 3.3V.

2. Digital Pin Connector.

Digital pins: P4,P5,P6,P7,P9,P10

G-3V3-S connector: 3V3 stands for 3.3V power voltage, G is for GND, S is for signal. GVS is a standard sensor connector, which enables you to plug onto servos and various sensors conveniently. At the same time, it supports our Octopus Bricks series'products.

3. 3.3V/5V dual electric level

GND-VCC-SIG connector:P13, P14, P15, P16, P19, P20.

The specialty of G-VCC-SIG connector lies in that it can support 3.3V or 5V power device by shifting electric level of 3.3V/ 5V through VCC connector. At the same time, it supports our Octopus Bricks series'products.

Motor Input Connector: Two motor input connectors in total. M1+, M1- and M2+, M2- separately controls a channel of DC motor.

M1,M2 Motor Control Instruction: P8 and P12 relatively controls the rotating direction of M1 and M2; P1 and P2 control motor speed.

Programming

Positive Rotation Of Motor:

P8 in high electric level means the positive rotation of motor. You can adjust the logic value of P1 to control motor speed. Negative Rotation Of Motor:

P8 in low voltage level means the negative rotation of motor. ou can adjust the logic value of P1 to control motor speed.
