13, 16, 17, 18 NC N/A Unused pin
2 TXD O UART0_TXD
3 RXD I UART0_RXD
4 PWM3 I/O Light drive interface, which can be used a GPIO
5 PWM1 I/O Light drive interface, which can be used a GPIO
6 3.3 V P Power-supply pin of TYZS12 (typical power supply voltage: 3.3 V)
7 nRST I Hardware reset pin, and the chip is reset when the level is low. TYZS12 has a power-on reset function, and this pin may be unnecessary in the actual situation.
8 3.3 V P Power-supply pin of TYZS12 (typical power supply voltage: 3.3 V)
9 PWM2 I/O Light drive interface, which can be used a GPIO
10 GPIO2 I/O GPIO
11 GPIO0 I/O GPIO
12 ADC AI Interface 1 of the ADC, which is a 12-bit precision SAR analog-to-digital converter
TP1 SWDI O I/O JLINK SWDIO programming pin, which can also be used as a GPIO in common programs
TP2 SWCL K I/O JLINK SWCLK programming pin, which can also be used as a GPIO in common programs

Note: P indicates power-supply pins, I/O indicates input/output pins, and AI indicates analog input pins. nRST is only a module hardware reset pin, which cannot be used to clear the ZigBee network configuration. nRST can be used only as an ADC port and not a common I/O port. When not being used, nRST must be disconnected. When nRST is used as an ADC input port, the input voltage range is 0 V to the AVdd which is configurable using software.

5. Antenna Information

5.1 Antenna Types

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

5.2 Antenna Interference Reduction

When you use a copper column antenna on a ZigBee module, ensure that the antenna on the module is at least 15 mm away from other metal parts for optimal wireless performance. It is recommended that the antenna location on the PCB be hollowed out. To prevent negative impact on antenna radiation performance, do not route copper or cable wires along the antenna area of the user PCB board.

6. Packaging Information and Production Instructions

6.3 Production Instructions

Storage conditions of a delivered module are as follows:

1.The anti-moisture bag must be stored in an environment with the temperature and humidity lower than 30° C and 85% RH, respectively. 2.The shelf life of a dry-packaged product is six months from the date when the product is packaged and sealed.

Note: 1.During the whole process of production, all operators must wear the electrostatic ring and electrostatic clothing. 2.During operations, strictly protect the module from water and strains.
