Introduction to BLE Module--TYBLC3

Introduction to BLE Module–TYLC3

1.Product Overview

TYLC3 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. TYLC3 include a 32- bit CPU, BLE/2.4G radio, 512K byte flash, 16k SRAM and 4-channel PWM.

Users can customize their LED products by using these PWM signals. Figure 1 shows the block diagram of the TYLC3.

5.Antenna Information

5.1 Antenna Type

Antenna can be connected using On-board PCB antenna only.

5.2 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.

6. Packaging Information And Production Guide

6.1 Mechanical Dimensions

​ Figure 3. Dimensions of the module

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 < 30℃ 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.
