Lima has 802.11N 2x2 radio supporting up to 300 Mbps data-rate and comes in two versions: commercial or industrial temperature

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 Carambola 2 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.

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