1.1 General Features

The WL1837MODCOM8I EVB includes the following features:

  • WLAN, Bluetooth, and BLE on a single module board
  • 100-pin board card
  • Dimensions: 76.0 mm (L) x 31.0 mm (W)
  • WLAN 2.4- and 5-GHz SISO (20- and 40-MHz channels), 2.4-GHz MIMO (20-MHz channels)
  • Support for BLE dual mode
  • Seamless integration with TI Sitara and other application processors
  • Design for the TI AM335X general-purpose evaluation module (EVM)
  • WLAN and Bluetooth, BLE, and ANT cores that are software- and hardware-compatible with prior WL127x, WL128x, and BL6450 offerings for smooth migration to device
