ZigBee module introduction--TYZS5(Engineering version)1. Product overviewThe TYZS5(Engineering version) is a low-power embedded Zigbee module developed by Hangzhou Tuya Information Technology Co., Ltd. The module consists of a EFR32MG13P732 highly integrated wireless RF processor chip and a small number of peripheral devices. It has a built-in 802.15.4 PHY/MAC Zigbee network protocol and a large number of library functions. The TYZS5 embeds a low-power 32-bit ARM Cortex-M4 core, 512KByte Flash program memory, 64KB RAM data memory, and a wealth of peripheral resources.
The TYZS5(Engineering version) is a FreeRTOS platform that gathers all Zigbee MAC and TCP/IP libraries into one place. It enables users to build on the product and develop embedded Zigbee products that suit their individual needs.
The TYZS5 (Engineering Edition) supports the engineering version of the app configuration intelligent solution, batch-free network one-click configuration of equipment, scenarios, and apartment types; support engineering data management platform data visualization management, monitoring landing project progress, service stability.

Module interfaces2.1 Package dimensionsThe TYZS5 (Engineering version) has 2 rows of pins with a 2mm gap and a total of 14 external pins.
TYZS5(Engineering version) dimensions: 14.8mm (W) x 20.4mm (L) x 2.0mm (H). TYZS5(Engineering version) dimensions are as shown in Figure 2:

2.2. Pin definitionInterface pins are defined as shown in Table 1:
Table 1, TYZS5 interface pins description
Pin numberSymbolIO TypeFunction
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, RX serial port.
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"s an internal connection to the 3.3V network, no external handling is necessary.
11 TXD O UART0_TXD, TX serial port.
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 analog input pin.
nRST 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.
