Description
- PI-POE25W is compatible with Raspberry PI 3B+,PI4,CM3/CM3+/CM4,etc…
- PI-POE25W is compatible with IEEE 802.3at (25.5W), IEEE 802.3af (13W)
- Output Voltage 5V, Peak current up to 5A, continuous current 4.5A
- PI-POE25W is a small size module 65mm*56mm*9.5mm (L*W*H), with a small size, low noise fan(Fan Maxim Speed 6500 RPM only 23 dB)
- PI-POE25W Fan Speed can be controlled by software through I2C (GPIO2, GPIO3), easy setup, come with Quick Start, we provide design service for raspberry pi
Size:PI-POE25W
InnoMaker PI PoE 25w module fan Maximum Speed up to 6500 RPM, Fan Speed can be controlled by software through I2C (GPIO2, GPIO3), When power up, it runs at maxim speed;
Quick Start:
Step1:
Edit config.txt by command ‘sudo nano /boot/config.txt’, add ‘dtparam=i2c_arm=on,dtparam=i2c_vc=on’ and save file;
Step2:
Install tools by command ‘sudo apt-get install i2c-tools’, ‘sudo reboot’ ;
Step3:
Check I2C Bus Quantity by command ‘i2cdetect -l’ ,’i2cdetect -y 1′ ;
Step3:
Set PWM initialize By Total 4 commands (Must run all 4 command )
‘i2cset -f -y 1 0x62 0x00 0x00’
‘i2cset -f -y 1 0x62 0x01 0x04’
‘i2cset -f -y 1 0x62 0x08 0x03’
‘i2cset -f -y 1 0x62 0x02 0xff’ ;
Step4:
We normally set it by command, ‘i2cset -f -y 1 0x62 0x06 0xff’ ;
Note: ‘value 00-ff, 00 means max, ff means minimum, when the value is less than 80, the fan will have noise, so the recommended value between 80-ff’ ;
Step5:
Check Temperature by command ‘/opt/vc/bin/vcgencmd measure_temp’
