Many users prefer the ESP32 when implementing WiFi & Bluetooth into their IoT projects. But Ai-Thinker BW16 offers dual-band WiFi 4 & Bluetooth 5.0 connectivity through Realtek’s RTL8720DN chipset which may provide more reliable connectivity where the 2.4 GHz band is crowded.
The module integrates an Arm Cortex-M4F compatible high-performance MCU, an Arm Cortex-M0 compatible low power MCU, WiFI 802.11 a/b/g/n, MAC, Bluetooth and RF baseband, and provides a set of configurable GPIO ports to control peripheral devices.
One significant difference between BW16 and ESP32 module is that it has two serial port interfaces, so attention should be paid to the wiring of the UART interfaces. The following diagram shows the two serial interfaces of the BW16 module.
The secondary LOG serial port is also accessible as shown in the figure above in order to print debug messages and/or download the firmware.
Ai Thinker’s dual-band module can be used in various applications including manufacturing, the Smart Home, Smart Agriculture, as well as in the hospitality sector.
