Description
The HLK-M50 is a wireless serial WiFi module designed for smart home IoT applications. It integrates various components such as MCU, PMU, clock, and IEEE802.11b/g/n MAC/PHY/radio, and supports 2.4GHz WiFi, USB, Micro SD, UART, I2C, I2S, PMW, and SPI interfaces. It runs on mbedOS5.1 operating system and has two versions - one with WiFi serial transmission function and the other for secondary development. The second development version offers a variety of interfaces for users to develop their own applications using C or C++. The module has 96K Bytes of user SRAM, 32K Bytes of icache, and 8Mbit flash memory. It also supports up to 17 GPIO ports and 2 serial ports with configurable baud rate. Additionally, it has 2 I2S interfaces and 1 I2C interface with support for master or slave operation and 3 standard speed modes.
