- Tx output power: up to +8.5dBm
- Rx Sensitivity: up to -96dBm
- 50 Ω matched single-pin antenna input
- RSSI monitoring with +/-1 dB resolution
- Auto acknowledgment, retransmission, and flow control
1.1.2 Power Management Features
- Low power controller by Near-Threshold level power consumption
- Battery monitor for low battery voltage detection
- Brownout detection/shutoff and Power-On-Reset
- Multiple-power-state to optimize power consumption
2. User Manual
2.1 Supply Power
The TLSR9518ADG80D supports supply power via USB. As shown in Figure 2-1, the USB port is the primary power input; power can be supplied when the USB is plugged in.
Figure 2-1 USB power supply: A diagram illustrating the PCB layout of the Telink Dongle TLSR9518ADG80D, with the USB port clearly marked as the power input.
As shown in Figure 2-2, the marker indicates the 3.3V and GND port. 3.3V power can be supplied through these two ports.

2.2 Download Firmware
Firmware can be downloaded via two methods: USB burning or SWS burning. This process requires the Telink Burning EVK. The Telink Burning EVK features a USB port and 3.3V/SWS/GND ports. To download firmware using USB, connect the dongle's USB to the Burning EVK. For SWS download, connect the dongle's 3.3V/SWS/GND pins to the corresponding 3.3V/SWM/GND pins on the Burning EVK.
2.3 Functions of Each Module
As illustrated in Figure 2-3, the functions of each module on the board are marked. The dongle includes a PCB antenna for transmitting data packets. Onboard components include an LED, a button, and a debug port. The LED lights indicate the status of the TLSR9518ADG80D. The button allows control of the TLSR9518ADG80D, and the debug port can be used for debugging the dongle.
The TLSR9518ADG80D also supports headphone and microphone functions, which can be realized according to different software configurations.
