Variants of the Banana Pi RV2
Banana Pi offers two versions of the RV2 Board: the standard model and an upgraded version that comes with an integrated, soldered to the board Power over Ethernet (PoE) module.
The PoE feature allows routers and other network devices to transmit both data and electrical power over a single Ethernet cable. While routers themselves are not typically powered via PoE, they often serve as Power Sourcing Equipment (PSE)—delivering power to other devices.
Routers equipped with Power over Ethernet (PoE) technology are commonly utilized in settings where a centralized power supply and streamlined cabling are crucial. Here are several applications of Power over Ethernet:
- Wireless Access Points (WAPs): Routers with PoE ports can power WAPs, enabling flexible placement without needing nearby electrical outlets.
- IP Cameras: Security systems benefit from PoE routers that power surveillance cameras, especially in hard-to-reach areas.
- VoIP Phones: Office routers with PoE can power VoIP phones, reducing clutter and simplifying installation.
- IoT Devices: Smart sensors, environmental monitors, and access control systems can be powered directly from PoE-enabled routers.
An in-depth look at the board
Fantastic buy. OpenWRT compatible only on the snapshot version, but it runs smoothly. Strange choice to put PoE on the WAN port: my LAN switch has PoE, so I swapped WAN and one of the LAN ports to make it work.
I understand. Yes, it’s cheap, good quality, and works well.
Bought a CR1220 battery, but no way to have RTC work.
Bought an M.2 disk, but it seems not recognized (maybe because is a SATA one, not NVME: very difficult to find M.2 NVME disks with B-Key).
Lacks a lot of informations and settings…
Try the ImmortalWrt snapshot, its better. SATA shouldn’t work, so your right.
