VLinK E901 2.4G WiFi 6 plus BLE 5.1 IOT Module Instructions

The E901WiFi 6 +BLES.1 IOT module uses ESWIN&IECR6600, a single-band 2.4GHz Combo (802.llax +BLES.1) chip line. It uses WiFi/BLE coexistence architecture, which can meet the re□irements of low latency, long distance and low power application scenarios at the same time, and pro@le big data transmission sercvice.

The ECR6600 uses built-in PM Us compatible with DC-DC/LDO modes, high-performance PA, and high-gain LNA and digital filters to improve power conversion efficiency, realize dynamic power output, and protect the device against interference in complex environments

The ECR6600 adopts lxl radio architecture, uses OFDMA technology to support multi-user access, optimizes data stream transmission based on lxl space, and the transmission rate can be increased by 25%.

On the safe side, the ECR6600 uses the WPA3 security mechanism to provide two-way authentication protection for smart home and mobile payment portals. In addition, the E901 has a simple design with a 24x16mm universal IOT module size that meets FCC/CE/SRRC certification requirements.

Preheating zone: The temperature is from 40 ° C to 150 ° C, the temperature rise rate is controlled at about 2 ° C /s, and the temperature zone time is 60 ~ 150s.

Average temperature zone: the temperature is 150℃ ~ 200℃, steadily and slowly rising, the temperature rise
rate is less than 1℃/s, and the time in the region is controlled at 60 ~ 120s (Note: the region must be slowly heated, otherwise it is easy to lead to bad welding).
Reflux zone: temperature from 217℃ ~ Tmax ~ 217℃, the whole interval time is controlled at 60 ~ 90s. Cooling zone: The temperature is from Tmax to 180℃, and the maximum temperature drop rate can not exceed 4℃/s.
The temperature from room temperature 25℃ to 250℃ should not exceed 6 minutes.

The reflow curve is recommended only. The client needs to adjust it according to the actual production situation.
The target reflux time is 60 to 90s. For some boards with large heat capacity that cannot meet the time requirements, the reflux time can be set relax to 120s.

JEP140 recommendation: For devices with small thickness, the thermocouple is directly attached to the surface of the device when measuring the temperature of the package, and for devices with large thickness, the thermocouple is drilled into the surface of the device for measurement. Due to the requirements of quantifying the thickness of the device, it is recommended to use all the holes in the surface of the package buried in the thermocouple type (especially thin devices, except drilling is not possible).

Radiation Exposure Statement

This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20cm between the radiator and your body.
This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. Country Code selection feature to be disabled for products marketed to the US/ Canada.
This device is intended only for OEM integrators under the following conditions:

1. The antenna must be installed such that 20 cm is maintained between the antenna and users, and
2. The transmitter module may not be co-located with any other transmitter or antenna,
3. For all products market in US, OEM has to limit the operation channels in CHl to CHll for 2.4G band by supplied firmware programming tool. OEM shall not supply any tool or info to the end-user regarding to Regulatory Domain change. (if modular only test Channel 1-11)

As long as the three conditions above are met, further transmitter testing will not be required. However, the OEM integrator is still responsible for testing their end-product for any additional compliance requirements required with this module installed.

Important Note:

In the event that these conditions cannot be met (for example certain laptop configurations or co-location with another transmitter), then the FCC authorization is no longer considered valid and the FCC ID cannot be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization.

End Product Labeling

The final end product must be labeled in a visible area with the following”
Contains FCC ID: 2AXX8-E901-NI-WS”

Manual Information to the End User

The OEM integrator has to be aware not to provide information to the end user regarding how to install or remove this RF module in the user’s manual of the end product which integrates this module.
The end user manual shall include all required regulatory information/warning as show in this manual.
