Overview

Rambutan is based on QCA 9557 or QCA 9550 SoC and comes in two temperature ranges: commercial* (Rambutan) and industrial** (Rambutan-I).

IT is a surface mountable, dual-sided, Wi-Fi enabled Linux module.

Dual-band radio (2.4 or 5 GHz), powerful 720 MHz CPU, 300 Mbps data-rate, 128 MB RAM and Flash and a development kit with multiple interfaces (e.g. Gigabit Ethernet port, PCIe, hardware SPI etc.) are the main advantages of the Rambutan module.

OpenWRT linux distribution source code is available on GitHub and is supported by our growing community on forum.

*Commercial temperature range: 0-65°C, **Industrial temperature range: -40-85°C
