Serial port to WIFI transparent transmission test version
HLK-M20 WiFi module integrates DBB/PMIC/RF/PA/Memory/LNA/Balun and supports 2.4GHz IEEE 802.11b/g/n.
The module is quite excellent in power consumption control. Rx power consumption is 1/2 of the same type of low-power WiFi modules on the market, Tx power consumption is only 70% of theirs, and power consumption in deep sleep mode is only 8uA, DTIM1 power consumption is 0.9mA.

Product HLK-M20 supports serial port to WiFi STA, serial port to WiFi AP mode
·In this mode (STA mode), through settings, the data of COM1 and WiFi can be converted mutually.
·WiFi security supports the current mainstream encryption methods.
·In this mode (AP mode), through settings, the data of COM1 and WiFi can be converted mutually.
·The WiFi device can connect to the product and become a device under the WiFi LAN.
·WiFi security supports the current mainstream encryption methods.
