Rambutan
Product brief
Rambutan is based on QCA 9557 or 9550 SoC
and comes in two temperature temperature
ranges: commercial (Rambutan-C) and industrial
(Rambutan-I).
IT is a surface mountable, dual-sided, Wi-Fi
enabled Linux module.
Daul-band radio (2.4 or 5 GHz), powerful
720 MHz CPU, 300 Mbps data-rate, 128 MB
RAM and Flash, Gigabit Ethernet port and
a development kit with multiple interfaces
(e.g. PCIe, hardware SPI etc.) are the main
advantages of the Rambutan module.
OpenWRT linux distribution source code is
available on GitHub https://github.com/8devices
and is supported by our growing community on
http://www.8devices.com/community forum.
