UCTRONICS PoE hat for Raspberry pi

For Pi 4 and 3 B+: This PoE HAT can be used to deliver clean and reliable power to the raspberry pi 3 model B+ and raspberry pi 4 model B (not included)..
Intelligent Temperature Control: the 25mm×25mm brushless cooling fan will turn automatically when the temperature of the processor is high..
Smaller Size: Save more space than the official HAT, can be held in the most case for Raspberry Pi.We recently released a new version of PoE HAT with fan, which can support 48V non-standard switches, please search B09MCGFX12.
NOTE: The network switch or power sourcing equipment (PSE) is needed to supply the PoE signal, and they must be compliant with the IEEE 802.3af or 802.3at PoE standard, particularly section 33.4.1 with regards to PSE electrical isolation of the leads. For the non-isolated switch, such as some Ubiquiti switches can not provide proper isolation, they can only work with CAT 5E and CAT 6E network cable..

Isolation Amplifiers 4.5 - 5.5 SV 8 dB (5 pieces)

Isolate and amplify the weak control signal (only a few milliamps of current) by photoelectricity, and finally output a higher power control signal to directly drive the motor, contactor, solenoid valve, etc..
The response time is as low as milliseconds and there is no limit on the number of switches. It can directly replace traditional relays, reducing maintenance time and costs..
Photoelectric isolation is used between the input stage and the output stage, and the two stages are completely independent, which effectively avoids the instability caused by mutual interference of the system and effectively protects the output node of.
Made of high-quality electronic components, stable and reliable performance..
Hole punching and PCB module mounting are more convenient..
