RDA5981 serial port WIFI transparent transmission module can be developed twice / voice remote / HLK-M50 external pin version

Introduction:

The HLK-M50 WiFi module is a low- that integrates MCU, PMU, clock, and IEEE802.11b / g / n / PHY / radio.
Module supports 2.4GHz IEEE802.11b / g / n, USB Host and Device 2.0 HS, Micro SD card (SDMMC interface), UART, I2C, , PMW, and 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 or ++. Development kit to provide a large number of guidance documents and routines to facilitate rapid development of users.
