TYWE5P Module Datasheet

Product Overview

TYWE5P is a low-power built-in Wi-Fi module developed by Hangzhou Tuya Information Technology Co., Ltd. It consists of a highly integrated radio frequency chip (ESP8266) and several peripheral components, with a built-in Wi-Fi network protocol stack and robust library functions. TYWE5P is embedded with a low-power 32-bit CPU, 1 MB flash, 50 KB SRAM, and robust peripheral resources.

TYWE5P is an RTOS platform that integrates all the function libraries of the Wi-Fi MAC and TCP/IP protocols. You can develop built-in Wi-Fi products as required.

5	GND	P	Power supply reference ground pin
6	GPIO0	I/O	GPIO_0 (Used during module power-on and initialization. Use it with caution.)
7	VCC	P	Power supply pin of the module (3.3 V)
8	GPIO2	O	UART0_TXD (used for printing the internal information of the module)
9	GPIO15	O	GPIO_15 (Used during module power-on and initialization. Use it with caution.)
10	GPIO13	I/O	GPIO_13
11	GPIO12	I/O	GPIO_12
12	GPIO14	I/O	GPIO_14
13	GPIO16	I/O	GPIO_16 (Connect it to a 10 KΩ pull-up resistor.)
14	EN	I	Module enablement pin. Connect it to 3.3 V power supply. (The module has been connected to a pull-up resistor.)
15	RST	I/O	Hardware reset pin (It is valid at low level and has been connected to a pull-up resistor.)

Note:

• P indicates power-supply pins, I/O indicates input/output pins, and AI indicates analog input pins.
• RST is only a hardware reset pin of the module, which cannot clear the Wi-Fi network configuration.
• UART0 is a user serial port. When the module is powered on and started, data is exported from the serial port, which can be ignored.

Antenna Information

Antenna Types

Only the onboard PCB antenna is used.

Antenna Interference Reduction

When using an onboard PCB antenna on a Wi-Fi module, make sure that the antenna on the module is at least 15 mm away from other metal parts to ensure optimal wireless performance.

To prevent a negative effect on antenna performance, do not route copper or cable wires along the antenna area of the user PCB board.

For details about the area of the onboard PCB antenna on a module, see Figure 3.

Production Instructions

Storage conditions of a delivered module are as follows:

1. The anti-moisture bag must be placed in an environment where the temperature is under 30°C and the relative humidity is under 85%.
2. The shelf life of a dry-packaged product is six months from the date when the product is packaged and sealed.

Note:

1. Throughout the production process, each involved operator must wear an electrostatic ring.
2. During the operation, strictly protect the module from water and strains.
