Lima

Product brief

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-C) 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 memmory options (up to 

128 MB RAM and up to 64 MB Flash) and a 

development kit with more interfaces (e.g. PCIe) 

are the key differentiators from Carambola 2 

module.

OpenWRT linux distribution source code is
