MikroTik R52HnD Wireless miniPCI Network Card for ISP & Business Deployments

MikroTik R52HnD is a dual-band 2.4/5 GHz miniPCI wireless card with two chains, designed for MikroTik devices with a miniPCI slot that require capable wireless connectivity across both bands. It is an improved version of the popular R52Hn, delivering higher transmit power and enhanced ESD protection up to ±15 kV — relevant for outdoor installations or environments with electrostatic discharge risk.

The card supports 802.11a/b/g/n standards on both bands, with a maximum data rate of 300 Mbps and a dual-chain configuration for more stable connections and better coverage compared to single-chain cards. The AR9220 chipset and Wi-Fi 4 support ensure broad compatibility with client devices in mixed installations — covering both legacy and modern hardware. A maximum power draw of 7W and a tested operating range of -40°C to +70°C make it suitable for outdoor deployments in demanding climatic conditions.

The R52HnD installs in any MikroTik device with a standard miniPCI slot and uses two MMCX connectors for antenna cables. The active band — 2.4 GHz or 5 GHz — is selected in RouterOS, allowing the card to be adapted to the specific requirements of the installation without replacement.

Recommended for MikroTik devices with a miniPCI slot requiring high-power dual-band wireless with ESD protection for outdoor or technical installations, for upgrading from single-chain cards or earlier generations, and for any scenario where the flexibility to operate on either 2.4 GHz or 5 GHz within a single card is a requirement.
