1. Product Overview
ZS3L is a low-power embedded Zigbee module that Tuya has developed. It consists of a
highly integrated RF processor chip (EFR32MG21A020F768IM32-B) and several
peripheral components, with an embedded 802.15.4 PHY/MAC Zigbee network protocol
stack and robust library functions. ZS3L is embedded with a 32-bit low-power Arm
Cortex-M33 core, 768 KB flash memory, and 64 KB random-access memory (RAM), and
has extensive peripherals.
ZS3L is a FreeRTOS platform that integrates all the function libraries of the Zigbee MAC
and TCP/IP protocols. You can develop embedded Zigbee products as required.

5. Antenna Information
5.1 Antenna Type
ZS3L uses an onboard PCB antenna
5.2 Antenna Interference Reduction
To ensure optimal Zigbee performance when the Zigbee module uses an onboard PCB
antenna, it is recommended that the antenna be at least 5 mm away from other metal
parts.
To prevent adverse impact on the antenna radiation performance, avoid copper or traces
along the antenna area on the PCB.

6.2 Recommended PCB Layout
Figure 6-3 ZS3L pins
ZS3L can be mounted onto a PCB by using an SMT placement machine or through-hole
mounted onto the PCB through a pin header. Figure 6-4 shows the pin header
dimensions.

6.3 Production Instructions
1. Use an SMT placement machine to mount the stamp hole module that Tuya produces
onto the PCB within 24 hours after the module is unpacked and the firmware is
burned. If not, vacuum pack the module again. Bake the module before mounting it
onto the PCB.
(1) SMT placement equipment
i. Reflow soldering machine
ii. Automated optical inspection (AOI) equipment
iii. Nozzle with a 6 mm to 8 mm diameter
(2) Baking equipment
i. Cabinet oven
ii. Anti-static heat-resistant trays
iii. Anti-static heat-resistant gloves
2. Storage conditions for a delivered module are as follows:
(1) The moisture-proof bag is placed in an environment where the temperature is
below 30°C and the relative humidity is lower than 70%.
ZS3L Datasheet
Hangzhou Tuya Information Technology Co., Ltd. 16 V1.0.1
(2) The shelf life of a dry-packaged product is six months from the date when the
product is packaged and sealed.
(3) The package contains a humidity indicator card (HIC).
Figure 6-6 HIC for ZS3L
3. Bake a module based on HIC status as follows when you unpack the module
package:
(1) If the 30%, 40%, and 50% circles are blue, bake the module for 2 consecutive
hours.
(2) If the 30% circle is pink, bake the module for 4 consecutive hours.
(3) If the 30% and 40% circles are pink, bake the module for 6 consecutive hours.
(4) If the 30%, 40%, and 50% circles are pink, bake the module for 12 consecutive
hours.
4. Baking settings:
(1) Baking temperature: 125±5°C
(2) Alarm temperature: 130°C
(3) SMT placement ready temperature after natural cooling: < 36°C
(4) Number of drying times: 1
(5) Rebaking condition: The module is not soldered within 12 hours after baking.
5. Do not use SMT to process modules that have been unpacked for over three months.
Electroless nickel immersion gold (ENIG) is used for the PCBs. If the solder pads are
exposed to the air for over three months, they will be oxidized severely and dry joints
or solder skips may occur. Tuya is not liable for such problems and consequences.
6. Before SMT placement, take electrostatic discharge (ESD) protective measures.
7. To reduce the reflow defect rate, draw 10% of the products for visual inspection and
AOI before first SMT placement to determine a proper oven temperature and
component placement method. Draw 5 to 10 modules every hour from subsequent
batches for visual inspection and AOI.
6.4 Recommended Oven Temperature Curve
Perform SMT placement based on the following reflow oven temperature curve. The

8. Appendix: Statement
Federal Communications Commission (FCC) Declaration of Conformity
FCC Caution: Any changes or modifications not expressly approved by the party
responsible for compliance could void the user's authority to operate this equipment.
This device complies with Part 15 of the FCC Rules.Operation is subject to the following
two conditions: (1) This device may not cause harmful interference, and (2) this device
must accept any interference received, including interference that may cause undesired
operation.
Note: This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to part 15 of the FCC Rules.These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This
equipment generates, uses and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the
user is encouraged to try to correct the interference by one or more of the following
measures:
—Reorient or relocate the receiving antenna.
—Increase the separation between the equipment and receiver.
—Connect the equipment into an outlet on a circuit different from that to which
the receiver is connected.
—Consult the dealer or an experienced radio/TV technician for help.
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 minimum
distance 20cm between the radiator and your body.
Important Note
This radio module must not installed to co-locate and operating simultaneously with other
radios in host system except in accordance with FCC multi-transmitter product procedures.
Additional testing and equipment authorization may be required to operating
simultaneously with other radio.
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 to 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
ZS3L Datasheet
Hangzhou Tuya Information Technology Co., Ltd. 21 V1.0.1
this manual, including: This product must be installed and operated with a minimum
distance of 20 cm between the radiator and user body.
This device have got a FCC ID：2ANDL-ZS3L.The final end product must be labeled in a
visible area with the following: “Contains Transmitter Module FCC ID:2ANDL-ZS3L”
This device is intended only for OEM integrators under the following conditions:
1) The antenna must be installed such that 20cm is maintained between the antenna and
users, and
2) The transmitter module may not be co-located with any other transmitter or antenna.
