描述

樹莓派 Raspberry Pi – I2C 16 Channel PWM Servo & L293D-2 4 Motor Board

一、產品特色

1. This board use RS-Pi GPIO 17,18,27,22,23,24,25,4

GPIO 17,18,27,22   for  MA1, MB1

GPIO 23,24,25,4     for  MA2, MB2

2. GPIO 28 ~31  (need V2 – P5 connector) for ultrasonic sensor connector (2GPIO, one for Trig, one  for Echo) or other devices

3. 2 extra 12c input for sensors  (5V or 3v3) (5V port with Level converter)

switch S1 TO S5 ( use GPIO 7,8,9,10,11 signal)  (SPI signal)

Rs-Pi- 16channel PWM & 4 Motor Board plug in Raspberry Pi

二、Scratch驅動應用範例 Detail

(1) Servo Motor control

2 Servo in channel 0 & channel 7  Command “SE”+ “PWM (0-15)” + “a” +”angle” for Address 41  se7a10 –> channel 7 servo move 10 angle address 41 se7a-10 –> channel 7 servo move -10 angle address 41 se0a10 –> channel 0 servo move 10 angle address 41 se0a-10 –> channel 0 servo move -10 angle address 41
