TLSR 8266 TUYA TYBT2 BluetoothBLE Module Chip Develop and Design Description

TYBT1 is a Bluetooth (BLE) module designed by HangZhou Tuya Technology Corporation, which is designed for outputting LED control signals. The BLE Module consists of a highly integrated wireless Bluetooth chip TLSR8266 and some extra electric circuits that have been programed with Bluetooth network protocol and plenty of software examples. TYBT1 include a 32- bit CPU, BLE/2.4G radio, 512K byte flash, 16k SRAM, 5-channel PWM, one I2C and one UART interface.

Users can customize their LED products by using these PWM signals. Figure 1 shows the block diagram of the TYBT1.

PIN NO.	NAME	TYPE	DESCRIPTION
1	SDA	I/O	I2C, data interface, internal pull-up 4.7k resistance
2	SCL	I/O	I2C, clock interface, internal pull-up 4.7k resistance
3	G	I/O	normal IO pin, can be used as PWM output pin, default for Green LED line
4	B	I/O	normal IO pin, can be used as PWM output pin, default for Blue LED line
5	WW	I/O	normal IO pin, can be used as PWM output pin, default for Warm White LED line
6	CW	I/O	normal IO pin, can be used as PWM output pin, default for Cold White LED line
7	R	I/O	normal IO pin, can be used as PWM output pin, default for Red LED line
8	3.3V	P	Supply voltage
9	TX	I/O	UART TX,can be used as normal IO pin
10	RX	I/O	UART RX,can be used as normal IO pin
11	GND	P	Ground
12	SW	I/O	Bluetooth chipset burning pin
13	RST	I	reset pin for the module,internal pull-up 4.7k resistance
14	GND	P	Ground

Note:P: Power supply pins; I/O: Digital input or output pins.

SW pin is ONLY used for burning firmware, Can NOT be used for other functions.

While Pin4 and Pin12 are used for I2C functions, external 4.7k pull-up resistances are necessary.

When WW pin is outputting PWM signal, It has opposite phase comparing the PWM signal from R/G/B/CW pin.

If there's any customization needed for PWM output, please contact our BD manager.

5.Antenna Information

5.1 Antenna Type

Antenna for TYBT2 module is using 2.4 GHz MIFA On-board PCB antenna.

5.2 Reduce Antenna Interferencey

In order to have the best RF performance, it's recommended to keep a minimum 15mm distance between the antenna part and the other metal pieces.

Since PCBA manufacture use SMT process to weld TYBT2 module and other electrical components onto the PCB board, RF performance will depend on the layout location and pattern of the On-board PCB antenna. The following figures are some recommended and dis-recommended demonstrations from out R&D team.

In demonstration 1 and 2 of figure 3, the on-board PCB antenna lays outside of the PCB frame. It's recommended to use layout pattern shown in demonstration 1 and 2. Either the on-board PCB antenna lays outside of the PCB frame directly or PCB frame carve out a certain area for the antenna. The overall PCBA performance for these two ways will be the same as testing the module independently.

Restricted due to some reason, if the on-board PCB antenna layout has to be inside the PCB frame, it's suggested to refer to demonstration 3. The antenna lays inside the PCB frame, but no copper or wire beneath the antenna. RF performance will have some loss, approximately 1~2 dBm.

It's NOT recommended to use demonstration 4, the antenna lays inside the PCB frame, and there are copper and wire beneath it. RF performance will have significant attenuation.

6.2 Production Guide

The storage for the delivered module should meet the following condition:

1. The anti-moisture bag should be kept in the environment with temperature < 30ºC and humidity < 85% RH.
2. The expiration date is 6 months since the dry packaging products was sealed.

Cautions:

1. All the operators should wear electrostatic ring in the whole process of production.
2. While operating, water and dirt should not have any contact with the modules.
