Pin definition

Table 2.1 describes the interface pins.

​ Table 2.1, TYLC3V interface pins

Pin Symbol I/O Type Functions
1 WW I/O PWM2_N, common I/O interface, which can be used for PWM output of the LED driver. It controls the warm white LED by default.
2 GND P Power supply reference ground pin
3 VIN P Power supply input pin
4 3.3 V P Power supply output pin
5 CW I/O PWM4, common I/O interface, which can be used for PWM output of the LED driver. It controls the cold white LED by default.
6 B I/O PWM1, common I/O interface, which can be used for PWM output of the LED driver. It controls the blue LED by default.
7 G I/O PWM0, common I/O interface, which can be used for PWM output of the LED driver. It controls the green LED by default.
8 R I/O PWM5, common I/O interface, which can be used for PWM output of the LED driver. It controls the red LED by default.
  • P indicates power-supply pins and I/O indicates input/output pins.
  • When the WW pin is used for PWM output, its polarity is opposite to that of the R, G, B, and CW pins used for PWM output. If you have special requirements for the light color controlled by PWM output, contact our business manager.

Antenna Information

Antenna type

​ TYLC3V uses the plug-in spring antenna working in the 2.4 GHz Wi-Fi band for the PCB.
Figure 5.1 shows the antenna dimensions.

Antenna Interference Reduction

​ To ensure optimal RF performance, it is recommended that there be a space of at least 15 mm between the module antenna and other metal parts. The antenna must be far away from the PCB and high devices, especially high metal parts.

If the distance is too small, the electromagnetic wave radiated by the antenna generates the induced electromotive force at the edge of the PCB. In this case, an induced magnetic field is generated, which consumes some energy of the original electromagnetic field, reducing the antenna radiation efficiency. It is recommended that the antenna be at least 15 mm away from the PCB.

Production Instructions

Storage conditions of a delivered module are as follows:

  • The anti-moisture bag is placed in an environment where the temperature is under 30°C and the relative humidity is under 85%.
  • The shelf life of a dry-packaged product is six months from the date when the product is packaged and sealed.

Precautions:

  • Throughout the production process, each involved operator must wear an electrostatic ring.
  • During the operation, strictly protect the module from water and strains.
