Product Overview
BW16 is a dual-band Wi-Fi + Bluetooth SoC module based on RTL8720DN. BW16 supports dual frequency (2.4GHz or
5GHz) WLAN and Bluetooth Low Energy 5.0; it integrates ARM V8 (Cortex-M4F compatible) high-performance MCU, ARM V8M
(Cortex-M0 compatible) Low-power MCU, WLAN (802.11 a / b / g / n), MAC, Bluetooth baseband and RF
Baseband, and provides a set of configurable GPIO ports for control of different peripheral devices.
BW16 also integrates internal memory to support simple application development, enabling complete Wi-Fi and BT
5.0 Protocol Features.

powered by(1) Recommended 3.3V voltage, peak current above 500mA
(2) It is recommended to use LDO power supply; if using DC-DC, it is recommended to control the ripple within 30mV.
(3) The DC-DC power supply circuit is recommended to reserve the position of the dynamic response capacitor, which can optimize the output when the load changes greatly.
Ripple.
(4) It is recommended to add an ESD device to the 3.3V power interface.
Use of GPIO port
(1) Some GPIO ports are led out of the module. If you need to use, it is recommended to connect a 10-100 ohm resistor in series with the IO port.
This can suppress the overshoot, and the level on both sides is more stable. Helps both EMI and ESD.
(2) The special IO port is pulled up and down, please refer to the instruction manual of the specification. This will affect the startup configuration of the module.
(3). The IO port of the module is 3.3V. If the IO level of the main control and the module does not match, a level conversion circuit needs to be added.
(4) If the IO port is directly connected to a peripheral interface, or a pin or other terminal, it is recommended to reserve ESD near the terminal of the IO cable
Device.
