Rambutan is a high-performance dual-band Wi-Fi 4 SoM built on the versatile Qualcomm QCA 9557/9550 SoC. This capable SoM has found its way into numerous successful industrial applications due to its scalable price point.
8devices does not recommend this SoM for new product designs.
Rambutan supports FirmUx Networking, which is a proprietary embedded Linux framework that provides developers with powerful tools and integration procedures. Use it to unlock powerful network features and build your own full-featured firmware and device software. Rambutan also supports open source QSDK.
