Overview

TI WiLink™ 8 module family The WL1837MODCOM8I is one of the two evaluation boards for the TI WiLink™ 8 combo module family. For designs requiring performance in the 2.4 GHz band only, see the WL1835MODCOM8.

The WL1837MODCOM8I, which is compatible with many processors including TI’s Sitara™ processors, easily enables customers to add both Wi-Fi® and Bluetooth® to home and building automation, smart energy, gateways, wireless audio, enterprise, wearables and many more industrial and Internet of Things (IoT) applications. TI’s WiLink 8 modules are certified and offer high throughput and extended range along with Wi-Fi and Bluetooth coexistence in a power-optimized design. Drivers for the Linux and Android high-level operating systems (HLOSs) are available free of charge from TI for the Sitara AM335x microprocessor (Linux and Android version restrictions apply).
