Overview

The diagram below illustrates the main components and default jumper settings on the TLSR9518ADK80D. It supports the functions listed here in the default setting:

• RF conducted test
• External Flash with reset button
• Chip reset button
• Mini USB interface
• 2-wire JTAG, default
• 4 LEDs, Key matrix up to 4 keys
• 2 line-in function (Dual Analog microphone supported when switching jumper from microphone path)
• Dual Digital microphone
• Stereo line-out

The TLSR9518ADK80D board features:

• USB connector
• RF SMA connector
• Chip Reset button
• Flash Reset button
• JTAG interface
• Multiple jumpers for configuration (e.g., SW1, SW2, SW3, SW4, SW5, SW6)
• LED indicators
• Key matrix inputs
• Audio connectors (e.g., A-MIC-L, A-MIC-R, SPK-R, SPK-L)
• Various pin headers for GPIO and other interfaces.

Power connection method with Telink Burning Board

TLSR9518A supports an easy debug method. Only three wires are needed:

• 5V from Telink Burning Board is connected to VBUS on TLSR9518ADK80D.
• SWM from Telink Burning Board is connected to SWS on TLSR9518ADK80D.
• GND from Telink Burning Board is connected to GND on TLSR9518ADK80D.

The Telink Burning Board connects to the TLSR9518ADK80D board via three wires: GND, SWS, and VBUS.

Power connection method with TLSR9 DEV KEY

A RISC-V core is embedded in TLSR9518A, enabling JTAG debug support. The 2x6 connector on the left of the mini USB interface is the JTAG interface. Initially, connect the TLSR9 DEV KEY to the JTAG interface using DuPont wires one by one. Subsequently, use the Telink IDE tool to download the firmware. Ensure the DIP button is in the correct setting. It supports a 2-wire JTAG interface when the “1” button is on and the “2” button is off. Conversely, it supports a 4-wire JTAG interface when the “1” button is off and the “2” button is on.

The TLSR9 DEV KEY has a 5V LDO. Therefore, when connecting the TLSR9 DEV KEY with the TLSR9518ADK80D via DuPont wires, a USB cable is not required. A USB cable is only necessary when using the USB function.

The TLSR9 DEV KEY connects to the TLSR9518ADK80D via DuPont wires to the JTAG interface, which includes pins for TRST, TDI, TDO, TCK, TMS, SRST, and GND.

RF test

First, power on the device. Then, connect the RF SMA through a cable to the equipment or through the whip antenna when verifying the chipset or developing functions. The corresponding tool is an EMI tool, which can be obtained from the wiki.

The setup involves connecting the TLSR9518ADK80D board to test equipment using either an RF cable for conducted tests or a whip antenna for radiated tests.

Dual analog microphone function

The dual analog microphone function is enabled by following the jumper settings as shown in the diagram. The diagram highlights the relevant jumpers on the TLSR9518ADK80D board for enabling this function.

Audio input path test

The dual analog microphone function is enabled by default. When testing the audio input path, adjust the jumper settings as indicated. Other jumpers should remain in their original positions. An audio analyzer, such as the APx525, can be used for testing.

The diagram shows the TLSR9518ADK80D board with audio input cables connected, leading to an audio analyzer. The connections are labeled as 'AIR' and 'AIL'.

Audio output path test

All jumpers are kept in the default setting for the audio output path test. The connection of the audio output path is shown below. An audio analyzer, such as the APx525, can be used for testing.

The diagram shows the TLSR9518ADK80D board with audio output cables (SPK-R and SPK-L) connected to an audio analyzer.

Audio input/output path demo

Sometimes, users want to listen to music directly during the development stage. The connection for this demo is shown below.

The diagram illustrates the TLSR9518ADK80D board connected to an audio source and an earphone for direct audio playback.

GPIO test

All GPIOs of the TLSR9518A have been connected to PINs. Users can then refer to the corresponding schematic and test all GPIOs.
