Vender PoE HAT ule Power Ethernet Expansion Board for Raspberry Pi 4B/3B+ al mejor precio

The Power-over-Ethernet (POE) ule offers a convenient and cost-effective way to deliver power to your device. The ule allows you to put a DC voltage onto specific pairs of the Ethernet cable so that devices connected to the network can use it as a power source. The ule is Perfect for any space limited PoE applications such as IP cameras, biometric readers, RFID, wireless access points, HDBaseT extenders, VOIP phones, networked audio etc. It's tiny size is a perfect match to the Raspberry Pi 4B and 3B+ in IOT and building automation applications. It is ultimate power solution for Raspberry Pi 4B/3B+. It delivers clean and reliable power to the latest Pi 4. Warning: PoE power output must be within the budget of the switch when powering multiple boards!!! STANDARDS COMPLIANT POWER OVER ETHERNET SWITCH REQUIRED!!! The network switch or power sourcing equipment (PSE) 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. "Passive PoE" (DC 24V or 48V) is not standards compliant and may cause damage to equipment. Do not use this product in an enclosed case without active air circulation!! Product Features: Easy to assemble Compatible With: Raspberry Pi 4 el B / Raspberry Pi 3 el B+ Built-in Cooling Fan Input: IEEE 802.3af Compliant PoE Output: 5V +-5% up to 2.5A Protection Circuitry: Transient Overvoltage, Undervoltage Lockout, Thermal Shutdown, Foldback Current Limiting Active airflow and adequate cooling required for stable continuous operation at high load. colour: blue Material: plastic Package Contents: 1 x HAT ule 1 set x installation accessoriesOnly the above package content, other products are not included.
