TB-02 Specification V1.0

1.INTRODUCTION

The TB-02 intelligent lighting module is a Bluetooth module based on the TLSR8250F512

chip and compatible with BT 5.0 low-power Tmall Genie Mesh. This module supports the

Bluetooth module directly controlled by Tmall Genie and has a Bluetooth mesh networking

function. Peer-to-peer network communication, using Bluetooth broadcast for communication,

can ensure timely response in the case of multiple devices. It is mainly used in intelligent light

control, which can meet the requirements of low power consumption, low latency, and

short-range wireless data communication.

Features

 Can be directly controlled by Tmall Elf without a gateway

 1.6mm pitch pin vertical solder DIP18 package

 6 PWM outputs

 With on-board antenna, no need to design antenna

 Brightness (duty cycle) adjustment range 5% -100%

 Factory default 50% duty cycle for cool and warm colors

 PWM output power 1KHz

 With night light function

 With wall switch to switch color temperature function

6.DESIGN GUIDE

1、Application circuit

2、Antenna layout requirements

(1) Place the module on the edge of the motherboard, and the antenna area extends beyond the edge of

the motherboard.

3、Electricity Supply

(1) Recommended 3.3V voltage, peak current above 50mA (2) It is recommended to use LDO power supply; if using DC-DC, it is recommended to control the ripple within 30mV. (3) The DC-DC power supply circuit is recommended to reserve the position of the dynamic response capacitor, which can optimize the output ripple when the load changes greatly.

XII

TB-02 Specification V1.0

(4) 3.3V power interface is recommended to add ESD devices.

4、PWM Dimming Solution Design Instructions

For lamps that require dimming, you only need to connect the PWM pins of the corresponding color to the control end of the subsequent stage drive circuit; the PWM independently outputs a 100-level adjustable digital signal, and the subsequent stage circuit can be voltage The driving type may be a current driving type.

Connection diagram

5、LED Drive Reference Design

TB-02 module application only needs 3.3V power supply and simple driving circuit to achieve intelligent light control. Take MOS tube to drive a channel of white light as an example, the design reference is as follows; CW_I is the module's positive white light PWM output , Q1 is MOS tube, WW is LED lamp beads, the other 4 road lamp driving circuit is the same as this road design method.

6、Secondary development

The TB-02 module supports users to write their own firmware programs to achieve customized functions.

If you use a Linux machine to develop the firmware, you can refer to the SDK, documentation and source address of Anxin's collation:

https://github.com/Ai-Thinker-Open/Telink_825X_SDK.

If you use Windows development, you can refer to the original SDK provided by the chip manufacturer. Download address:

This exterior label can use wording such as the following: “Contains Transmitter Module FCC ID:2ATPO-TB-02 Or Contains FCC ID:2ATPO-TB-02” When the module is installed inside another device, the user manual of the host must contain below warning statements;

1. 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. (2) This device must accept any interference received, including interference that may cause undesired operation. Note: 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.

Changes or modifications not expressly approved by the party responsible for compliance could void the user's

2. authority to operate the equipment. The devices must be installed and used in strict accordance with the manufacturer's instructions as described in the user documentation that comes with the product. Any company of the host device which install this modular with limit modular approval should perform the test of radiated & conducted emission and spurious emission,etc. according to FCC part 15C : 15.247 and 15.209 &

15.207 ,15B Class B requirement, Only if the test result comply with FCC part 15C : 15.247 and 15.209 & 15.207 ,15B Class B requirement，then the host can be sold legally.
