Pin definition

The following table shows pins of the module:

Pin number	Symbol	Type	Function
1	nRST	I	Hardware reset pin. The chip is reset when the level is low. TYZS1L has a power-on reset function, and this pin is not necessary in the actual situation.
2	ADC	AI	Interface 1 of the ADC (a 12-bit precision SAR analog-to-digital converter), corresponding to the PB11 pin of the IC.
3	NC	-	NC pin. External processing is not required.
4	GPIO0	I/O	Functions as a GPIO, corresponding to the PA3 pin of the IC.
5	SWO	I/O	Functions as a GPIO or an output pin in the JLINK communication state, corresponding to the PF2 pin of the IC.
6	PWM3	I/O	Functions as a GPIO, corresponding to the PF4 pin of the internal IC.
7	PWM1	I/O	Functions as a GPIO, corresponding to the PF5 pin of the internal IC.
8	VCC	P	Power-supply pin of TYZS1L (typical power-supply voltage: 3.3 V).
9	GND	P	Module reference ground pin.
10	GPIO2	I/O	Functions as a GPIO, corresponding to the PA5 pin of the IC.

Antenna

Antenna types

By default, the onboard PCB antenna is used. In addition, external antennas can be connected through I-PEX connectors, which are applied to extend the coverage in complex installation environments.

Antenna interference reduction

When you use an onboard PCB antenna on a Zigbee module, make sure that the antenna on the module is at least 15 mm away from other metal parts to ensure optimal wireless performance. It is recommended that the antenna location on the PCB be hollowed out.
To prevent a negative effect on antenna radiation 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

• The stamp-hole module must be mounted by the SMT machine. After being unpacked, it must be soldered within 24 hours. Otherwise, it must be put into the drying cupboard where the RH is not greater than 10%, or it needs to be packaged under vacuum again and the exposure time needs to be recorded (the total exposure time cannot exceed 168 hours).

  • SMT equipment:
    • Mounter
    • SPI
    • Reflow soldering machine
    • Oven temperature tester
    • Automated optical inspection (AOI) equipment
  • Baking equipment:
    • Cabinet oven
    • Anti-static heat-resistant pallets
    • Anti-static heat-resistant gloves

• Storage conditions for a delivered module are as follows:

  • 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.
  • The package contains a humidity indicator card (HIC).
    

• The module needs to be baked in the following cases:

  • Vacuum packing bag was found to be damaged before being unpacked.
  • There is no humidity indicator card (HIC) in the vacuum packing bag.
  • After being unpacked, 10% and above circles on the HIC become pink.
  • The total exposure time has been more than 168 hours since unpacking.
  • More than 12 months have passed since the sealing date of the bag.

• Baking settings:

  • Temperature: 60°C and ≤ 5%RH for reelizing and 125°C and ≤5%RH for palletizing (please use heat-resistant pallet rather than plastic pallet)
  • Time: 48 hours for reelizing and 12 hours for palletizing
  • Alarm temperature: 65°C for reelizing and 135°C for palletizing
  • Production ready temperature after natural cooling: < 36°C
  • The number of drying times: 1
  • Re-baking condition: If a module remains unused for 168 hours after being unpacked, it must be baked again.

    Important: If this batch of modules is not baked within 168 hours, do not use the wave soldering to solder them. Because these modules are 3-level moisture-sensitive components, they are very likely to get damp when exposed outside. In this case, if they are soldered at high temperatures, it may result in component failure or poor soldering.

• In the whole production process, take electrostatic discharge (ESD) protective measures.

• To guarantee the passing rate, it is recommended that you use the SPI and AOI to monitor the quality of solder paste printing and mounting.

Recommended oven temperature curve

Perform mounting with the SMT based on the following reflow oven temperature curve. The highest temperature is 245°C. The reflow temperature curve is as below:

• 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

• G: Peak temperature: 235 to 245°C

• H: Ramp-down slope: 1 to 4°C/s

  Note: The above curve is just an example of the solder paste SAC305. For more details about other solder pastes, please refer to Recommended oven temperature curve in the solder paste specifications.
