TYZS9V is a low power-consuming embedded Zigbee module developed by Hangzhou Tuya Information Technology Co., Ltd. It consists of a highly integrated wireless radio processor chip (EFR32MG13P732IM48-C) and several peripherals, with a built-in 802.15.4 PHY/MAC Zigbee network protocol stack and robust library functions. TYZS9V is embedded with a 32-bit low power-consuming ARM Cortex-M4 core, 512 KB flash, 64 KB RAM data memory, and robust peripheral resources. TYZS9V runs on the FreeRTOS platform that integrates all Zigbee MAC library functions. You can develop built-in Zigbee products as required. Figure 1 shows the architecture of TYZS9V. Figure 1 TYZS9V architecture
TYZS9V provides two rows of pins with the distance of 2.0 mm between every two pins. TYZS9V size: 26 mm (W) x 16 mm (L) x 1 mm (H) Figure 2 shows the overall pin layout of TYZS9V. Figure 2 Front and back views of TYZS9V
Table 1 describes the interface pins. Table 1 TYZS9V interface pins | No. | Symbol | I/O Type | Functions | | ------------ | -------- | ------------ | ------------------------------------------------------------ | | P1.1 | GPIO0 | I/O | Functions as a GPIO, corresponding to the PA3 pin of the internal IC. | | P1.2 | GND | P | Module reference ground pin | | P1.3 | VIN | P | A pin for external DC power supply and supports a maximum of 30 V DC power supply. | | P1.4 | 3.3V | P | A pin for 3.3 V voltage and can be used to output 3.3 V power supply. | | P2.1 | PWM1 | I/O | Functions as a GPIO and can output PWM signals to control lights. It corresponds to the PF5 pin of the internal IC. | | P2.2 | PWM3 | I/O | Functions as a GPIO and can output PWM signals to control lights. It corresponds to the PF4 pin of the internal IC. | | P2.3 | PWM2 | I/O | Functions as a GPIO and can output PWM signals to control lights. It corresponds to the PA2 pin of the internal IC. | | P2.4 | GPIO2 | I/O | Functions as a GPIO, corresponding to the PA5 pin of the internal IC. | | TP1 | nRST | I | Hardware reset pin, and the chip is reset when the level is low. TYZS9V has a power-on reset function, and this pin is not necessary in the actual situation. | | TP2 | ADC | AI | ADC port(1),12-bit precision SAR analog-to-digital converter. | | TP3 | SWCLK | I/O | JLINK SWCLK programming pin, which can also be used as a GPIO in normal programs. | | TP6 | SWDIO | I/O | JLINK SWDIO programming pin, which can also be used as a GPIO in normal programs. | | TP5 | TXD | O | UART0_TXD communication interface, corresponding to the PA0 pin of the internal IC. | | TP4 | RXD | I | UART0_RXD communication interface, corresponding to the PA1 pin of the internal IC. | 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 clear the Zigbee network configuration. (1): This pin can only be used as an ADC interface and cannot be used as a common I/O pin. If this pin is not used, it must be disconnected. When this pin is used as the ADC input interface, the input voltage range must be 0 to AVDD, which can be configured using software.

By default, the onboard PCB antenna is used. The antenna gain is about 2.0 dBi.
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 negative effect on antenna radiation performance, do not route copper or cable wires along the antenna area of the user PCB board.
