Placa-mãe Mikrotik RB912UAG-2HPND Single-Band 2,4 GHz Wi-Fi 4

The RB912UAG-2HPnD motherboard is a compact single-band 2.4 GHz Wi‑Fi 4 (802.11n) router board designed for integration into router devices and custom network setups. It includes an integrated high‑power 2.4 GHz wireless card, an additional miniPCIe slot for a secondary 802.11 wireless card or a 3G modem, Gigabit Ethernet and a USB Type‑A port. The board supports PoE and operates at 8–30 V with typical power consumption of 13.5 W. Built‑in 16 kV ESD protection is provided on both Ethernet and MMCX ports.

Advantages

The motherboard combines an integrated high‑power 2.4 GHz radio with an extra miniPCIe slot for flexible expansion, enabling addition of a second wireless card or a 3G module. Gigabit Ethernet allows higher throughput to match 802.11n speeds, while PoE support and compact dimensions (105 x 105 mm) simplify installation in various enclosures. The 16 kV ESD protection on Ethernet and MMCX ports increases reliability in environments prone to electrostatic discharge.

Suitable for

• Small routers and gateway devices
• Custom wireless access points on the 2.4 GHz band
• Deployments requiring a secondary miniPCIe wireless or 3G modem
• Environments needing Gigabit uplink for higher throughput
