TYWE2L Module Datasheet

TYWE2L is a low power-consuming built-in Wi-Fi module developed by Hangzhou Tuya Information Technology Co., Ltd. It consists of a highly integrated wireless radio chip (ESP8285) and several peripherals, with a built-in Wi-Fi network protocol stack and robust library functions.

Overview

​TYWE2L also provides a low power-consuming 32-bit CPU, 1 MB flash, 50 KB SRAM, and various peripheral resources.

TYWE2L is an RTOS platform that integrates all the function libraries of the Wi-Fi MAC and TCP/IP protocols. Users can develop embedded Wi-Fi products as required based on the function libraries.

​Figure 1 shows the schematic diagram of TYWE2L.

Module interfaces

Dimensions and footprint

TYWE2L provides two rows of pins with a distance of 2.0 mm between every two pins.

TYWE2L dimensions: 3 mm (W) x 15 mm (L) x 17.3 mm (H) (see figure 2)

Pin definition

Table 1 describes the interface pins.

​ Table 1 TYWE2L interface pins

Note: P indicates power-supply pins and I/O indicates input/output pins.

Test pin definition

Table 2 describes the test pins.

​Table 2 TYWE2L test pins

Note: I/O indicates input/output pins.

If IO0 is disconnected, the module enters the normal running state. If IO0 is at a low level, the module enters the firmware programming state.

Test pins are not recommended.

Antenna

Antenna type

​TYWE2L uses the onboard PCB antenna.

Antenna interference reduction

​To ensure optimal Wi-Fi performance when the Wi-Fi module uses the onboard PCB antenna, it is recommended that there be a space of at least 15 mm between the module antenna and other metal parts.

Packaging information and poduction instructions

Mechanical dimensions

Note: PCB frame tolerance ±0.15 mm, PCB depth tolerance ±0.1 mm

Production instructions

Storage conditions of a delivered module are as follows:

1. The anti-moisture bag is 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.

Precautions:

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.

Appendix: Statement

FCC Caution: Any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate this device.

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

Note: This device has been tested and found to comply with the limits for a Class B digital device, according to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This device generates, uses, and can radiate radio frequency energy and, if not installed and used following the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation.

If this device does cause harmful interference to radio or television reception, which can be determined by turning the device off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.
• Increase the separation between the device and receiver.
• Connect the device into an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.

Radiation Exposure Statement

This device complies with FCC radiation exposure limits set forth for an uncontrolled rolled environment. This device should be installed and operated with a minimum distance of 20cm between the radiator and your body.

Important Note

This radio module must not be installed to co-locate and operating simultaneously with other radios in the host system except following FCC multi-transmitter product procedures. Additional testing and device authorization may be required to operate simultaneously with other radios.

The availability of some specific channels and/or operational frequency bands are country dependent and are firmware programmed at the factory to match the intended destination. The firmware setting is not accessible by the end-user.

The host product manufacturer is responsible for compliance with any other FCC rules that apply to the host not covered by the modular transmitter grant of certification. The final host product still requires Part 15 Subpart B compliance testing with the modular transmitter installed.

The end-user manual shall include all required regulatory information/warnings as shown in this manual, including “This product must be installed and operated with a minimum distance of 20 cm between the radiator and user body”.

This device has got an FCC ID: 2ANDL-TYWE2L. The end product must be labeled in a visible area with the following: “Contains Transmitter Module FCC ID: 2ANDL-TYWE2L”.

This device is intended only for OEM integrators under the following conditions:

The antenna must be installed such that 20cm is maintained between the antenna and users, and the transmitter module may not be co-located with any other transmitter or antenna.

As long as the 2 conditions above are met, further transmitter tests will not be required. However, the OEM integrator is still responsible for testing their end-product for any additional compliance requirements required with this module installed.

Declaration of Conformity European Notice

Hereby, Hangzhou Tuya Information Technology Co., Ltd declares that this module product is in compliance with essential requirements and other relevant provisions of Directive 2014/53/EU,2011/65/EU. A copy of the Declaration of conformity can be found at https://www.tuya.com.

This product must not be disposed of as normal household waste, in accordance with the EU directive for waste electrical and electronic equipment (WEEE-2012/19/EU). Instead, it should be disposed of by returning it to the point of sale, or to a municipal recycling collection point.
