Plugwise Stretch 2.0 – Hardware

plugwise stretch 2.0

De hardware van de Plugwise Stretch 2.0 is een: Omnima EMB HMP (SKU 16190) met een Ralink RT3662F chip.
Besturingssysteem is Linux en standaard geleverd met OpenWrt / LuCi web configuration interface.

Let op: De software (Openwrt) ziet de RT3662F als een RT3883 chip.

De software van Plugwise dat geinstalleerd is op de Omnia EMB HMP kan eigen firmware zijn, de technische handleiding is (nog) niet op het internet te vinden.

Hardware:
• MIPS 74Kc 500MHz CPU
• 8 MB NOR Flash
• 64 MB SDRAM
• 1x WLAN 802.11n, access point (AP), station (STA), B, G, N or mixed mode operation
• 1x WAN/LAN Port 10/100M UTP
• 2x USB 2.0 OTG/OHCI/EHCI
• 1x UART serial port
• Antenna 3dBi Dipole detachable antenna x 2 (1 optional)
