2 Module Interfaces 2.1 Dimensions and Footprint TYZS3 has two rows of pins with a 2 mm pin spacing. TYZS3 dimensions (H x W x D): 2.6 mm x 16 mm x 24 mm Figure 2-1 shows the TYZS3 front and rear views. Figure 2-1 TYZS3 front and rear views 2.2 Pin Definition Table 2-1 TYZS3 interface pins Pin No. Symbol I/O Type 1 nRST I Hardware reset pin. When the pin is at a low level, the chip is reset. TYZS3 is reset upon power-on, and therefore, this pin may not be used. 2 ADC AI 12-bit precision SAR ADC.
Pin No. Symbol I/O Type Function 3 NC N/A NC pin. External processing is not required. 4 GPIO0 I/O Used as a GPIO. It corresponds to the PA3 pin on the internal IC. 5 SWO I/O Used as a GPIO or an output pin in J-Link communication state. It corresponds to the PF2 pin on the internal IC. 6 PWM3 I/O Used as a GPIO. It corresponds to the PF4 pin on the internal IC. 7 PWM1 I/O Used as a GPIO. It corresponds to the PF5 pin on the internal IC. 8 VCC P Power supply pin.
information. 3. This pin can be used as an ADC interface or a common I/O interface. It must be disconnected when not being used. When this pin is used as the ADC input interface, the input voltage range must be 0 to AVDD, which can be configured by using software. 2.3 Test Pin Definition Table 2-2 TYZS3 test pins Pin No. Symbol N/A N/A I/O Type I Function Used for the module production test Note: It is not recommended that test pins be used. 3 Electrical Parameters 3.

to connect the module to an external antenna to extend the coverage in a complex installation environment. If you use an I-PEX connector, the module BOM needs to be changed. For the I-PEX connector version, contact Tuya business personnel. 5.2 Antenna Interference Reduction To ensure optimal wireless performance when the Zigbee module uses an onboard PCB antenna, it is recommended that the antenna be at least 15 mm away from other metal parts and that the antenna location on the PCB be hollowed out.
