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.

(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). Figure 6-5 HIC for TYWRD1S Bake a module based on HIC status as follows when you unpack the module package: (1) If the 30%, 40%, and 50% circles are blue, bake the module for 2 consecutive hours. -
Page 18: Recommended Oven Temperature Curve
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. Before SMT placement, take electrostatic discharge (ESD) protective measures. -
