Brief Introduction
Based on originally imported RF IC SI4463 form Silicon Labs, E10 series are small size Sub-1GHz SMD wireless transceiver module, with SPI interface
and 26M crystal oscillator, developed by Chengdu Ebyte. The 30dBm module with PA and LNA, the communication stability and distance are largely
improved.
E10 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.

● 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.

Make it ground well with large space for grounding and small power ripple. Filter capacitor is necessary and make sure it is close to pin VCC and
Air data rate for SPI shall not be too high，1Mbps is recommended.

When transmitting：GPIO2 = 0; GPIO3 = 1;
When receiving：GPIO2 = 1; GPIO3 = 0;
To control via SI4463, in the program initialization one can set pins as below:

6. FAQ
6.1. 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
Due to antenna quality or poor matching between antenna and module.
6.2. 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.
