Supply power
The TLSR8208ADK56D supports supply power via USB or other 3.3V power. As shown in figure 2-1, the marker is the USB 5V port. Power can be supplied when USB is plugged in.
As shown in figure 2-2, the marker is the USB to LDO 3.3V port. 3.3V power can be supplied through the two ports.
Figure 2-2 USB to LDO 3.3V power supply As shown in figure 2-3, the marker is the 3.3V and GND port.
Download firmware
There are one ways to download firmware, SWS burning. But need another burning tool Telink Burning EVK. Telink Burning EVK have 3.3V/SWS/GND port. When using SWS download firmware, connect 3.3V/SWS/GND of dongle to 3.3V/SWM/GND of Burning EVK. The connection mode is shown in Figure 2-3.
Functions of each module
As shown in figure 2-4, The functions of each module on the board have been marked.
There are LED, key, ANT, E2PROM port and debug port on board. The LED lights can indicate what status the TLSR820ADK56D is in. The key allow us to control TLSR8208ADK56D. We can use debug port to debug TLSR8208ADK56D.
FCC
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
This device complies with part 15 of the FCC Rules. Operation is subject to
the following two conditions:
(1) This device may not cause harmful interference, and
(2) this device must accept any interference received, including interference
that may cause undesired operation.This equipment complies with FCC exposure
limits set forth for an uncontrolled environment. This equipment should be
installed and operated with minimum distance of 20 cm between the radiator and
your body. This transmitter must not be co-located or operating in conjunction
with any other antenna or transmitter.
Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment
