The core processor of DT-W5G1 module adopts ultra-low power processor and 2G-5G dual-frequency chip. The chip integrates 32-bit microcontroller with 16-bit streamlined mode and 160 MHz main frequency in smaller size package. DT-W5G1 has a complete Wi-Fi network function, which can be used as a slave plane and carried on other host MCUs. DT-W5G1 can be booted directly from external Flash when it responds alone. The built-in cache memory can improve the system performance and optimize the storage system. In addition, DT-W5G1 can be used as Wi-Fi adapter only through SPI/SDIO or I2C/UART, and should be applied to any microcontroller-based design.

  • DT-W5G1 module supports standard IEEE802.11a/b/g/n protocol and complete TCP/IP protocol stack. Users can use this module to add networking functions to existing devices, or to build independent network controllers.
  • DT-W5G1 module for maximum practicability, Wi-Fi function embedded in other systems to provide unlimited possibilities.
  • DT-W5G1 module has the characteristics of wide bandwidth and long distance communication, and can be used for wireless image transmission.
