User Manual
1. Introduction
WD112 is a hosted IoE Smart Network module that enables wireless internet connectivity for any
device wishing to be monitored or managed remotely. The WD112 is architected for ultra-low
power consumption, with near-zero power consumption in power down modes with fast wakeup.
This module comes with a single band 1-stream 11n radio Qualcomm QCA4002 and a ST
STM32F411 processor in ARM Cortex-M4 operating at frequencies up to 100MHz. This module
has an extra 2MByte flash memory, in addition to the flash memory internal to the MPU.
2. Features
2.412-2.484 GHz for worldwide market.
IEEE 802.11n, single stream 1x1.
Single Rx front end for multiple applications.
Full security support: WPS, WPA, WPA2, WAPI, WEP, TKIP.
On-chip memory
Serial interfaces: 3x USART, 2x SPI, 3x I2C
ROM API support
3 low-power modes and wake-up from low-power modes
