Komikan is a dual-band 802.11ac Wave2 module with BT v4.1 support. Two integrated radios

(2.4 and 5GHz) can achieve up to 1.166Gbps data rates and are backed by a powerful 1GHz

MIPS24Kc CPU. The module is in LGA (land grid array) form and is ideal for designs restricted

by space. Komikan does not require heat-sink like other 802.11ac Wave2 modules and has low

power consumption specs. It has multiple I/O interfaces to connect peripherals and comes with

OpenWRT Linux operating system.
