JN5168 - Current Consumption

jianalai — Tue, 04 Apr 2017 05:14:44 GMT

I have using the different DR1174 board and JN5168 module to measure the current in deep sleep mode.

First DR1174 and JN5168 - 159uA

Second DR1174 and JN5168 - 33uA

Is it different version of module or board will affect the current consumption?

Why is it so?

yes, the different version of the board can affect the power consumption, please check that the boards has the same rev.

We have tested the different version of the board with same module and the different version of module with same board. The following is the test results.

1. 1st board and 1st module - 8.8uA

2. 2nd board and 1st module - 8.8uA

3. 1st board and 2nd module - 340uA

4. 2nd board and 2nd module - 340uA

Based on the test results, the version of board will not affect the power consumption, but the version of module will affect the power consumption.

The following the version of module we are using for the testing.

1st Module:

JN5168-001-M00

01199

ZSD342

FCCID:TYOJN5168M0

IC:7438A-CYO5168M0

2nd Module:

JN5168-001-M00

01069

ZSD322-Y

FCCID:TYOJN5168M0

IC:7438A-CYC5168M0

May I know which version of Module can achieve better power consumption?

Pls advise.

Yes. The power consumption is affected by the evaluation board. Both Module can get exactly same value of current as datasheet when directly measure the current from the Module.
