Plugs into the Raspberry Pi GPIO connector.
Has eight Blue LED's and controls up to 2 5V DC motors,
1. This board use RS-Pi GPIO 17,18,27,22 for two Motor
GPIO 17,18 for MA1 GPIO 27,22 for MB1
2, GPIO 17,18,27,22,23,24,25,4 with status LED easy too know the GPIO high/low
3. GPIO 23,24,25,4,7,8,9,10,11 have GPIO pin for software PWM (Servo Motor) or sensors
4. 2 i2c device input port J1 GND,5V,SDA,SCL
5V Port with Logic Level converter protect
J30 GND, 3V3,SDA,SCL
for plug-in other sensors(3.3V & 5V)
5. Red LED for Power Status for Motor (V+ input)
Full Support by our Pi_Scratch software can be very easy control by Scratch
(1) BASIC GPIO Motor control
BASIC GPIO Motor on off control
define GPIO 17,18,27,22, as output
1. GPIO 17,27 LED "ON" & 18,22 LED "OFF" car move forward
2. GPIO 18,22 LED "ON" & 17,27 LED "OFF" car move backward
3. GPIO 18,27 LED "ON" & 17,22 LED "OFF" car turn right
4. GPIO 17,22 LED "ON" & 18,27 LED "OFF" car turn left
5. GPIO 17,27 LED "OFF" & 18,22 LED "OFF" car STOP
(2) PWM GPIO Motor control
A - GPIO 17,18 Motor A B - GPIO 27,22 Motor B
command "Motor Name"+ "DM"+"speed"
speed (10 ~100) clockwise
speed (-10 ~ -100) anticlockwise
ADM100 DC Motor A full speed 100
BDM100 DC Motor B full speed 100
ADM50 DC Motor A speed 50
BDM50 DC Motor B speed 50
ADM-100 DC Motor A anticlockwise full speed 100
BDM-100 DC Motor B anticlockwise full speed 100
ADM0 DC Motor A stop
