ZS13S is a Zigbee module that Tuya has developed. It consists of a highly integrated wireless RF processor chip (EFR32MG21A020F768IM32-B), a few peripherals, a built-in 802.15.4 PHY/MAC Zigbee network protocol stack, and rich library functions.
ZS13S is embedded with a low-power 32-bit ARM Cortex-M33 core, 768-KB flash program memory, 64-KB RAM, and rich peripherals.
ZS13S integrates all function libraries of the Zigbee MAC and TCP/IP protocols. You can develop embedded Zigbee products as required.
ZS13S has three rows of pins with a 1.27 mm pin spacing.
The ZS13S dimensions are 15±0.35 mm (W)×18±0.35 mm (L) ×2±0.15 mm (H). The size of a pad of a single pin is 1.5 mm*0.7 mm. The dimensions of ZS13S are as follows:

By default, the copper column antenna is used. In addition, external antennas can be connected through IPEX connectors, which are applied to extend the coverage in complex installation environments.
The dimensions of the IPEX base:
When the Zigbee module uses a copper pillar antenna, to ensure the optimal performance of the antenna, it is recommended that the antenna be at least 15 mm away from other metal parts. It is recommended that the antenna area corresponding to the adapter plate be hollowed out.
To ensure the antenna radiation performance, the PCB should not be routed or clad with copper around the antenna area.
The ZS13S dimensions are 15±0.35mm (W)×18±0.35 mm (L) ×1±0.1mm (H).
The Tuya SMT module should be mounted by the SMT device. After being unpacked, it should be soldered within 24 hours. Otherwise, it should 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).
Storage conditions for a delivered module:
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.
There is a humidity indicator card (HIC) in the packaging bag.
The module needs to be baked in the following cases:
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.
Set oven temperatures according to the following temperature curve of reflow soldering. The peak temperature is 245°C.
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.

Radiation Exposure Statement
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled rolled environment. This equipment should be installed and operated with a minimum distance of 20cm between the radiator and your body.
This radio module must not be installed to co-locate and operating simultaneously with other radios in the host system except in accordance with FCC multi-transmitter product procedures. Additional testing and equipment authorization may be required to operate simultaneously with other radios.
The availability of some specific channels and/or operational frequency bands are country dependent and are firmware programmed at the factory to match the intended destination. The firmware setting is not accessible by the end-user.
The host product manufacturer is responsible for compliance with any other FCC rules that apply to the host not covered by the modular transmitter grant of certification. The final host product still requires Part 15 Subpart B compliance testing with the modular transmitter installed.
The end-user manual shall include all required regulatory information/warning as shown in this manual, including: This product must be installed and operated with a minimum distance of 20 cm between the radiator and user body.
The RF module is considered as a limited modular transmitter according to FCC rules. Even though the RF module gets an FCC ID, the host product manufacturer can not use the FCC ID on the final product directly. In these circumstances, the host product manufacturer integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining the FCC authorization by a Class II permissive change application or a new application.
