Antenna Type; Notes - Ebyte E01 Series User Manual

nRF24L01P wireless module

5. Antenna Type

The default 0R resistance of E01-ML01SP2 is as above(left), the antenna type is PCB; To change the antenna type as IPEX, then change the 0R resistance as the left
one. This is suitable for other E01 models.

6. Notes

[Static] High-frequency analog devices have static-sensitive characteristics. Please avoid human contact with the electronic components on the
module as much as possible (All our production processes are performed according to the IC manufacturer's official anti-static standards).
[Soldering] When soldering, the soldering iron needs to be well grounded. For mass production, the production personnel is required to wear a
grounded wired electrostatic wristband.
[Power] The quality of the power supply has a great influence on the performance of the module. Make sure that the power supply of the module
has a small ripple, and you must avoid large power jitter. It is recommended to use π-type filters (ceramic capacitors/tantalum capacitors + inductors).
[Ground] The module ground wire uses a single point grounding method. It is recommended to use a 0 ohm resistor or a 10 ohm inductor to
separate it from the reference ground of other parts of the circuit.
[Antenna] The antenna installation structure has a great influence on the performance of the module. Make sure that the antenna is exposed,
preferably vertically upwards. When the module is installed inside the enclosure, a good antenna extension cable can be used to extend the antenna outside
the enclosure. The antenna must not be installed inside the metal shell, which will cause the transmission distance to be greatly weakened.
[Interference] If there are wireless modules working at other bands within the same product, it is necessary to reasonably plan the frequency and
