Ai-Thinker BW16 is a dual-band WiFi & Bluetooth 5.0 IoT module (Sponsored)

Ai Thinker BW16 dual-band WiFi BLE 5.0 module

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. BW16 module 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. One of the module serial interfaces is used to send and receive AT commands to control connectivity from a host processor or microcontroller, while the other serial port is used […]

A comparison of ESP32-S3, ESP32-C3 and ESP8266 modules

ESP32-S3 vs ESP32-C3 vs ESP8266 modules

The ESP32-S3 chip is equipped with an Xtensa 32-bit LX7 dual-core processor clocked at up to 240 MHz, supports 2.4 GHz Wi-Fi and Bluetooth 5 LE, and boasts AI instructions, as well as a reliable security encryption engine, specially built for the AIoT market. Modules based on the ESP32-S3 processor bring many benefits to designers with support for Bluetooth Long Range mode, plenty of resources with 512 KB SRAM (TCM), 45 programmable GPIO pins, and rich communication interfaces. They can also handle high-speed Octal SPI flash with higher capacities, as well as off-chip PSRAM. So, what are the differences between the new ESP32-S3 modules, and typical ESP32-C3 and ESP8266 modules? Let’s find out.
