Remote Control

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.
