WiFi module introduction–TYLC2V

1. Product Overview

TYLC2V is a low power consumption module with built-in Wi-Fi connectivity solution designed by HangZhou Tuya Technology Corporation. The Wi-Fi Module consists of a highly integrated wireless radio chip ESP8266 and some extra component that has been programed with Wi-Fi network protocol and plenty of software examples. TYLC2V include a 32-bit CPU, 1M byte flash, 50k SRAM and various peripheral resources.

TYLC2V is a RTOS platform, embedded with all the Wi-Fi MAC and TCP/IP protocol function examples, users can customize their Wi-Fi product by using these software examples.

5.Antenna Signal

5.1 Antenna Type

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

5.2 Reduce Antenna Interference

While using the On-board PCB antenna, in order to have the best Wi-Fi performance, it’s recommended to keep a minimum 15mm distance between the antenna part and the other metal pieces.

User’s own PCBA design is recommended NOT to pass any wire, NOT do copper pour under the region of the module’s antenna, to avoid interferences.

6. Production Guide

6.1 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.
