HLK-B300 UART to WI FI6 Module Low Power Support Serial to WI FI STA/WI FI AP/BLE Compatible with TCP/IP Protocol (Test Kit)

The HLK-B300 is a low-cost embedded UART-Wi Fi (serial-to-wire less) module.; It features a built-in TCP-compatible/IP protocol stack and enables conversion between user serial ports and wire less networks (Wi Fi/BLE 5.4 ).; With the HLK-B300 module, traditional serial devices can transmit their data over the Internet without requiring any configuration changes, providing a complete and fast solution for users to transmit data from their serial devices over the network.; The system includes 20 MHz and 40 MHz, basebands supporting Wi Fi 802.11 a/b/g/n/ax and BLE 5.4.; ArmV8-M core, clock
speed: 160 MHz. Built-in 512 KB RAM and 4 MB embedded Flash memory.
Operating voltage: 2.13.
63 V (typical: 3.3 V).
