Power Connection Method

Step 1: The JTAG interface is located to the left of the mini USB interface. Please note “Telink” text orientation.

Step 2: Connect the TLSR9 DEV KEY to the JTAG interface using DuPont wires.

Step 3: With this connection in place, the Telink IDE tool can be used to download FW. Please ensure the DIP button is set correctly.

  • 2 wire JTAG interface is enabled when button 1 is on and button 2 is off.
  • 4 wire JTAG interface is enabled when button 1 is off and button 2 is on.
  • The TLSR9 DEV KEY includes a 5V LDO.
  • It is not necessary to have a USB connection if the TLSR9 DEV KEY is connected to TLSR9518ADK80D via DuPont wires.
  • USB connection via USB cable is only necessary when using the USB function.


RF Test

To verify or develop application:

  • Power on
  • Connect RF SMA to equipment either through cable or whip antenna.


Dual Analog Microphone Function

To enable the dual analog microphone function, the jumpers should be set as indicated in the diagram / picture below.


Audio Input Path Test

  • The Dual analog microphone function is enabled by changing jumper setting as shown in the diagram / picture below.
  • Other jumper settings should not be changed from their default positions.
  • Some audio analyzer can be used for testing, such as APx525.


Audio Output Path Test

  • All jumpers are kept in default setting, and the connection of audio output path is as below.
  • Some audio analyzer can be used for testing, such as APx525.


Audio Input/Output Path Demo

To enable audio functionality during development, please connect as shown in the diagram / picture below.



  • All GPIO’s of TLSR9518A are connected to pins to facilitate testing.
  • Please refer to design schematics for GPIO pin reference.
