TYSW-012 Round Universal Remote Control

Product Overview

TYSW_012 is an infrared (IR) universal remote control that Hangzhou Tuya Inc. has developed. It consists of a low-power TYWE3S Wi-Fi module, an IR emitter, and an integrated IR receiver. Figure 1 shows the TYSW_012 architecture.

Figure 1 TYSW_012 architecture

The TYWE3S module consists of a highly integrated RF chip (ESP8266) and several peripheral components, with a built-in Wi-Fi network protocol stack and robust library functions. It is embedded with a low-power 32-bit CPU, 1 MB flash memory, and 50 KB SRAM, and has extensive peripherals. TYWE3S is an RTOS platform that integrates all the function libraries of the Wi-Fi MAC and TCP/IP protocols. Figure 2 shows the TYWE3S architecture.

Production Instructions

Storage conditions for a delivered product are as follows:

1. The moisture-proof bag is placed in an environment where the temperature is below 30°C and the relative humidity is lower than 85%.

2. The shelf life of a dry-packaged product is six months from the date when the product is packaged and sealed.

Precautions:

1. Throughout the production process, each involved operator must wear an ESD wrist strap.

2. During the operation, strictly protect the product from water and stains.
