描述

樹莓派 Raspberry Pi – DC Power Bank Multi Function Board

一、產品特色

1. LM2596S：STEP DOWN POWER MODULE

2. Input voltage range: DC 7.2V to 12V (input voltage must be higher than the output voltage above 1.5V. Could not boost)

3. Output voltage range: DC voltage from 5V to 10V continuously adjustable, high efficiency (92%) of the maximum output current of 2A.

4. can use 7.2V battery or 9V/10V/12V DC power adapter input –> DC 5V output with 3.3V power regulator provide 3.3V power build-in 4 channel Logic Level converter, for 5V logic device input signal.

5. 2 –  5V i2c input port with Logic level converter

6. 1 – 3.3V i2c input port .

7. 8 GPIO  pin with 8 LED (GPIO 17,18,27,22,23,24,25,4)

8. 4 V2 P5 pin  with 4 LED (GPIO 28,29,30,31)

二、Scratch驅動應用範例 Detail

  Command GPWMLED”A” or “B” or “C” or “D”   A GPIO 17,18,27,22,23,24,25,4 B GPIO 28,29,30,31 C GPIO A + B Z STOP LED flashing

   S”speed 1 to 10″   1 fast   10 slow”

三、機械手臂控制示範 

1. Change Maplin Robot Arm from PC base, USB port to Raspberry Pi Base,

GPIO Motor Control,

2. remove Battery use 12V DC power adapter for Raspberry Pi and Robot Arm.

3.Use a.Rs-pi–L293D-3 6 Motor Board  –

Control Robot Arm 5 Motor (M1,M2,M3,M4,M5)

b.Rs-Pi-Power Bank Multi-function Board

Use DC12V adapter, provide Raspberry Pi 5V and

all the power for 5V DC Motor

4. xWindow control mode

Maplin-Arm.py       use keyboard and Mouse control

5.Scratch GPIO control mode

a. setting GPIO 17,18,27,22,23,24,25,4 as output
