1.Product Overview
The BW16-Kit development board is a core development board designed by B&T for the BW16
module, which continues the classic design of the NodeMCU development board, leading all I/O to
the pin headers on both sides, on board RGB light, developers can also connect peripherals according to
their own needs.Standard pin headers on both sides make operation easier when using bread boards for
development and commissioning.
BW16 is a dual-frequency Wi-Fi + Bluetooth SoC module developed based on RTL8720DN.It
supports dual-frequency (2.4GHz or 5GHz) WLAN and low power Bluetooth 5.0; and integrates
ARMV8 (Cortex-M4F) high performance MCU, ARM V8M (Cortex-M0) low power MCU,
WLAN (802.11 a / b / g / n), MAC, Bluetooth and RF baseband, and provides a set of
configurable GPIO ports for the control of different peripherals.
BW16 also integrates internal storage and supports simple application development for full Wi-Fi
and BT5.0 protocol capabilities.

Tips：
The BW16 module are electrostatic sensitive devices (ESD) and require special ESD
precautions typically applied to ESD sensitive components. Proper ESD handling and packaging
procedures must be applied throughout the processing, handling, transportation and operation of
anyapplication that incorporates the BW18 module. Don’t touch the module by hand or solder with
non-anti-static soldering iron to avoid damage to the module.
