                  1. The HLK-M50 WiFi module is a low-power chip that integrates MCU, PMU, clock, and IEEE802.11b/g/n MAC/PHY/radio modules.
                  2. The 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, and supports analog buttons (GPADC0).
                  3. The secondary development version (under development) provides a rich and easy-to-use development interface for users to develop their own applications based on mbedOS in C or C++. A large number of guidance documents and test routines are provided in the development kit to make it easy for users to start development quickly.
