HLK-M50 RDA5981 Serial Port Wireless WIFI Transparent Transmission Module Secondary Development Voic

Introduction: The HLK-M50 WiFi module is a low-power chip that integrates MCU, PMU, clock, and IEEE802.11b / g / n MAC / PHY / radio. Module supports 2.4GHz IEEE802.11b / g / n, USB Host and Device 2.0 HS, Micro SD card (SDMMC interface), UART, I2C, I2S, PMW, SPI and other interfaces, analog keys (GPADC0). Software using mbedOS5.1 operating system, has two versions : WiFi serial transmission function version and secondary development. Second development version provides rich development interface, users can develop their own applications based on mbedOS through C or C ++. Development kit to provide a large number of guidance documents and test routines to facilitate rapid development of users. Specifications:
