HLK-M50 RDA5981 Serial Port Wireless WIFI Transparent Transmission Module Secondary Development Voice Remote Control
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.
