Pin definition

Table 1 shows the general pin attributes of TYBT2-IPEX

Table 1. The typical pin definition of TYBT2-IPEX

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, which can be used as PWM output pin, default for Green LED line
4	B	I/O	Normal IO pin, which can be used as PWM output pin, default for Blue LED line
5	WW	I/O	Normal IO pin, which can be used as PWM output pin, default for Warm White LED line
6	CW	I/O	Normal IO pin, which can be used as PWM output pin, default for Cold White LED line
7	R	I/O	Normal IO pin, which can be used as PWM output pin, default for Red LED line
8	3.3V	P	Supply voltage
9	TX	I/O	UART TX, which can be used as a normal IO pin
10	RX	I/O	UART RX, which can be used as a 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

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 the WW pin is outputting the PWM signal, It has an opposite phase comparing the PWM signal from the R/G/B/CW pins. If there’s any customization needed for PWM output, please contact our BD manager.

Antenna information

Antenna type

TYBT2-IPEX requires an external 2.4GHz band antenna with an IPEX generation terminal on one end.

Reduce antenna interference

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. Also, in order to minimize the attenuation of RF performance and to facilitate the free emission of RF signals, the antenna is preferably placed close to the edge, meanwhile, the antenna cannot be surrounded by metal objects or blocked by some high devices.
To ensure good isolation, when there are two or more antennas of the same frequency band, the distance between the antennas should be widened as much as possible, it is preferably greater than 5 cm.

Production guide

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

The anti-moisture bag should be kept in an environment with temperature < 30°C and humidity < 85% RH.
The expiration date is 6 months since the dry packaging products are sealed.

Cautions:

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