Burning and Debugging Tools for TLSR9 Series


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.
