Get Lima DVKThis SoC provides a 650 MHz CPU, 32 MB flash, and 64 MB RAM memory
Lima is a highly capable and adaptable single-band Wi-Fi SoM built using the Qualcomm QCA 4531 SoC. Its form factor, connection specifications, and scalability have made it an essential element of countless successful IoT/IoE projects built around Wi-Fi 4 (MIMO 2×2).
Our Cherry module is a pin-to-pin compatible upgrade to Lima. Cherry delivers Wi-Fi 6 compatibility and other updated features in the same compact package. Is this the upgrade you’ve been looking for?
Lima 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. Lima also supports open source QSDK.
