The ESP32 Bluetooth® and WiFi enabled module RF-WM-ESP32B1 features a single core — a 32-bit RISC-V processor with a maximum clock speed of 160 MHz. It is equipped with 384 KB ROM, 400 KB SRAM, 8 KB RTC SRAM, and 4 MB Flash memory. Featuring an industrial-grade 40 MHz crystal oscillator, the module supports various advanced peripherals such as SPI, UART, I2C, I2S, and PWM. The low power consumption, compact size, long-range coverage, and robust interference resistance make it ideal for IoT devices, such as industrial automation, health care, consumer electronics, etc.
WiFi+BLE Combo Module
The combo module integrated a RISC-V-based processor with WiFi and Bluetooth LE 5.0 radios help building devices with great coverage and improved usability.
Support ESP-MQTT
The WiFi+Bluetooth module supports MQTT over TCP, SSL with mbedtls, MQTT over Websocket, MQTT over Websocket Secure.
Bidirectional Transparent Transmission
The WiFi BT module is embedded with WiFi transparent transmission protocol to realize rich functions with AT commands and also transmits data by serial port to MCU bidirectionally.
