TYWE1S is a low-power embedded Wi-Fi module that Tuya has developed. TYWE1S consists of a highly integrated wireless RF chip (ESP8266EX) and an external flash chip, with an embedded Wi-Fi network protocol stack and varied library functions.
TYWE1S 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.
TYWE1S further contains a low-power 32-bit CPU, 2-MB ﬂash memory, 36-KB static random-access memory (SRAM), and rich peripherals.
TYWE1S has two rows of pins with a 1.5 mm pin spacing. Each row has 9 pins.
The TYWE1S dimensions are 18±0.35 mm (W)×23.5±0.35 mm (L) ×3.1±0.15mm (H). The thickness of the PCB is 1.0 mm±0.1 mm.

- P indicates power supply pins, I/O indicates input/output pins, and AI indicates analog input pins.
- RST is only a module reset pin and cannot be used for clearing information about Wi-Fi network configuration.
- Pin 17 can only be used as an ADC interface but cannot be used as a common IO interface. Once not used, it needs to be pulled up.
- As an ADC input interface, the input voltage range is 0 to 1.0V.

TYWE1S uses two types of antennas: onboard PCB antenna and external antenna. By default, the onboard PCB antenna is preferred.
The user can modify the antenna access method by switching the jumper resistor: (TYWE1S is equipped with resistor 0omh/0402 red mark).
To ensure optimal Wi-Fi performance when the Wi-Fi module uses an onboard PCB antenna, it is recommended that the antenna be at least 15 mm away from other metal parts.
To ensure antenna performance, the PCB should not be routed or clad with copper in the antenna area. The main points of the layout: 1. Make sure that there is no substrate medium directly below or above the printed antenna. 2. Make sure that the area around the printed antenna is far away from the metal copper skin, so as to ensure the radiation effect of the antenna to the greatest extent.
Parameters of the U.FL RF connector are shown as below:
The moisture-proof bag must be placed in an environment where the temperature is below 40°C and the relative humidity is lower than 90%.
The shelf life of a dry-packaged product is 12 months from the date when the product is packaged and sealed.
There is a humidity indicator card (HIC) in the packaging bag.
Set oven temperatures according to the following temperature curve of reflow soldering. The peak temperature is 245°C.
A: Temperature axis
B: Time axis
C: Liquidus temperature: 217 to 220°C
D: Ramp-up slope: 1 to 3°C/s
E: Duration of constant temperature: 60 to 120s; the range of constant temperature: 150 to 200°C
F: Duration above the liquidus: 50 to 70s
