Lima is a QCA 4531 chipset based module with a 650 MHz CPU and 802.11N 2x2 (MIMO) radio. Module is available in two temperature ranges: commercial* (Lima) and industrial** (Lima-I).

Lima is a surface mountable, dual-sided, Wi-Fi enabled Linux module for the (IoE) internet of everything applications.

Faster CPU, 300 Mbps data-rate, low power consumption, larger 32 MB flash memmory and a development kit with more interfaces (e.g. PCIe) are the key differentiators from Carambola2 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
