Pin definition

Pin number Symbol IO type Function
1 PWM1 I/O Light driver port/GPIO pin usage.
2 PWM2 I/O Light driver port/GPIO pin usage.
3 I2C_SDA I/O I2C_SDA, GPIO pin usage.
4 I2C_SCL I/O I2C_SCL, GPIO pin usage.
5 VCC P Module power supply pin (common supply voltage: 3.3V)
6 ADC AI ADC, 12-bit precision SAR analog to digital converter
7 GND P The reference ground of the module.
0 SWDIO I/O JLINK SWDIO programming pin. Can be used as a GPIO pin in normal applications.
00 SWCLK I/O JLINK SWCLK programming pin. Can be used as a GPIO pin in normal applications.
8 RXD I/O UART0_RXD
9 nRST I Hardware reset pin, the chip is reset when the pin is LOW; Power-on reset of the module, the user can use this pin as needed
10 VCC P Module power supply pin (common supply voltage: 3.3V); Since there is an internal connection to the 3.3V network, no external handling is necessary.
11 TXD O UART0_TXD
12 GND P The reference ground of the module is internally connected to GND and does not need to be handled externally.

Description: P indicates the power pin; I/O indicates the input/output pin; AI indicates the analog input pin.

RST is only the module hardware reset pin; it cannot clear Zigbee net-pairing information.

(1): This pin can only be used as an ADC port. It cannot be used as a normal IO port. If it is not used, it needs to be left floating.

As an ADC input, the input voltage range is limited to 0-AVDD and can be configured by software.

Default PCB onboard antenna connection.

Antenna interference reduction

To optimize the Zigbee performance of the wireless module in combination with the PCB onboard antenna, it is recommended to keep the antenna at least 15mm from other metal parts.

The user PCB board should not be routed around the antenna area and should not be covered with copper to avoid affecting the antenna radiation performance. It is recommended that the adapter board antenna area be hollowed out.

For the module, PCB onboard antenna area, refer to the mechanical dimensions of TYZS2 below.

Note: Pin3/Pin4 is used by I2C communication or GPIO by default and can also be configured as a UART communication port using the software. Pin0/Pin00 is the JLINK programming interface. It can also be used as a normal I/O port after burning in the program. The default configuration of Pin8/Pin11 is the UART communication port.

Production guide

The storage conditions for the module after it has been shipped are as follows:

  1. The moisture-resistant bag must be stored at a temperature below 30℃, and under a relative humidity below 85%.

  2. The shelf life of dry-packedq13 products is 6 months following the packaged date.

Important:

  • All line workers must wear anti-static wrist straps and anti-static clothing throughout the entire production process.
  • It is strictly prohibited to allow a module to come into contact with water or other contaminants during operations.
