1. Product Overview

TYWRD1S is a low-power embedded Wi-Fi module that Tuya has developed. It consists

of a highly integrated RF chip (RDA5981B) and several peripheral components, with an

embedded Wi-Fi network protocol stack and robust library functions. TYWRD1S is

embedded with a low-power 32-bit CPU, 2 MB flash memory, and 448 KB static

random-access memory (SRAM), and has extensive peripherals.

TYWRD1S is an RTOS platform that integrates all function libraries of the Wi-Fi MAC and

TCP/IP protocols. You can develop embedded Wi-Fi products as required.

TYWRD1S Datasheet Note: 1. P indicates power supply pins, I/O indicates input/output pins, and AI indicates analog input pins. nRST is only a hardware reset pin and cannot clear the Wi-Fi network configuration. 2. This pin can only function as an ADC input and not a common I/O. If this pin is not used, it must be disconnected. When this pin is used as an ADC input, the input voltage range is 0 V to 1.0 V. 3.

Use an SMT placement machine to mount the stamp hole module that Tuya produces onto the PCB within 24 hours after the module is unpacked and the firmware is burned. If not, vacuum pack the module again. Bake the module before mounting it onto the PCB. (1) SMT placement equipment i. Reflow soldering machine ii. iAutomated optical inspection (AOI) equipment iii.

Anti-static heat-resistant gloves Storage conditions for a delivered module 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 70%. (2) The shelf life of a dry-packaged product is six months from the date when the product is packaged and sealed. (3) The package contains a humidity indicator card (HIC).

TYWRD1S Datasheet 5. Do not use SMT to process modules that have been unpacked for over three months. Electroless nickel immersion gold (ENIG) is used for the PCBs. If the solder pads are exposed to the air for over three months, they will be oxidized severely and dry joints or solder skips may occur. Tuya is not liable for such problems and consequences. 6. Before SMT placement, take electrostatic discharge (ESD) protective measures. 7.
