Brief Introduction
E01 series 2.4Ghz wireless transceiver module based on nRF24L01P with SPI interface features small size and various application usage.
E01 series modules are embedded with imported electronic parts, such as industrial crystals with high precision and TCXO. With built-in PA and LNA, the
20dBm module has better performance for communication and operating range; 0dBm modules with imported parts owns excellent RF performance, especially
popular among users who require low power consumption.
E01 series strictly stick to the design rules home and abroad of FCC, CE, CCC and meet the related RF certifications and export standards. As hardware
platform,users need to carry out secondary development.

●When designing current supply circuit, 30% margin is recommended
to be remained so as to ensure long-term stable operation of the
whole module;
●The current at the instant of transmitting may be high, but the total
energy consumed may be lower due to very short transmitting time;
●When using external antenna, the impedance matching degree at
different frequency points between antenna and module may affect
the transmitting current value at different levels.

be higher for some RF chips with communication protocol or the
developers have loaded their own protocol to the whole module;
● The current at pure receiving mode will be mA level, users can
realize µA level of receiving current through firmware development.

●If the module stays at maximum voltage for a long time, it may be
damaged;
● The power supply pin has certain surge-resistance ability, but the
potential pulse is higher than the maximum power supply voltage;
●The power supply is not advisable to be below 3.0V, or the RF
parameters will be influenced at different degree.
● For max 30dBm, voltage is no less than 4.75V，or RF parameters
will be affected to different extend.

● Due to the error of the materials, each LRC component has ± 0.1%
error, so error accumulation will occur since multiple LRC
components are used in the whole RF circuit, and the transmitting
currents will be different at different modules;
● The power consumption can be lowered by lowering the
transmitting power, but the efficiency of the internal PA will be
decreased by lowering transmitting power due to various reasons;
● The transmitting power will be lowered by lowering the power
supply voltage.

3. Recommended Circuit Diagram
No.
Brief introduction of connection between module and MCU (STM8)
1
CE pin can be high level for long-term, but it needs to set as POWER DOWN mode when the module writes registers, and it is
recommended that CE is controlled by MCU pin.
2
As interrupt pin for IRQ, it can be used to wake-up MCU and achieve fast response;
But the user can get the interrupt status through SPI (not recommended, it is not conducive to the overall power consumption, and with
low efficiency）.
4. Electrical Parameters

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

take measures such as shielding to reduce the influence of harmonic interference and inter-modulation interference.
[Crystal] If there is a crystal near the circuit board on the module, increase the linear distance between the crystal and circuit board as much as
possible.

8. FAQ
8.1. Communication range is too short
The communication distance will be affected when obstacle exists.
Data lose rate will be affected by temperature, humidity and co-channel interference.
The ground will absorb and reflect wireless radio wave, so the performance will be poor when testing near ground.
Seawater has great ability in absorbing wireless radio wave, so performance will be poor when testing near the sea.
The signal will be affected when the antenna is near metal object or put in a metal case.
Power register was set incorrectly, air data rate is set as too high (the higher the air data rate, the shorter the distance).
The power supply low voltage under room temperature is lower than the recommended value, the lower the voltage, the lower the transmitting power.
Due to antenna quality or poor matching between antenna and module.
8.2. Module is easy to damage
Please check the power supply source, ensure it is within the recommended value, voltage higher than that will damage the module.
Please check the stability of power source, the voltage cannot fluctuate too much.
Please make sure antistatic measure are taken when installing and using, high frequency devices have electrostatic susceptibility.
Please ensure the humidity is within limited range, some parts are sensitive to humidity.
Please avoid using modules under too high or too low temperature.
