Notice No Category Static Soldering Power supply Ground Antenna Interference Oscillator Notice High frequency analog device Avoid touching components on module if possible, since the high frequency analog device features electrostatic susceptibility Electric soldering iron must be well connected to ground when soldering Power supply quality influence on module performance, please insure the power supply will not appear big ripple to avoid dither in power supply. Module ground apply single point grounding. It's recommended to use ohm inductance or 10mH inductance and set it apart from reference ground of other circuit in other part. Mounting structure of module antenna influence module performance. Please insure little noise interference around antenna. Note: Antenna must not mount in metallic shell, otherwise the transmission distance be weakened greatly. If there are different frequency modules inside one product, the frequency should be well programmed to reduce the influence of harmonic interference and intermediation interference If there is oscillator close to the PCB in which module mount, please increase the distance between oscillator and PCB if possible. Typical Circuit MCU Note: 1. IRQ is a Interrupt Pin, which can be used to activate SCM to achieve quick response.IRQ could be unconnected to obtain interruption status by SPI(It' not recommended because of the low efficiency. And it will influence Power Consumption.) 2. CE can be connect to high voltage level for a long term， in this way write register must be set to POWER DOWN mode first. 3. Truth-value table for relationship between TX_EN and RX_EN as shown: Driver Statement 1. IC nRF24L01P+RFX2401 is adopted in this module, it's driving means is same as nRF24L01P, user can operate ELSP01 in accordance with manual for chip nRF24L01P. 2. Connect LNA EN to MCU, LNA=1(Opened), LNA=0(Closed) 3. If user want to achieve auto-answer, LNA should be in high level during transmit process, to ensure interface circuit be in working state. FAQ： ★ Communication distance is close which did not achieve specified value. With physical characteristics of poor penetrability for 1 Obstacle 2.5GHz frequency , communication distance loss will be increased when these is line communication failed. Interference from temperature, humidity and co-frequency 2 interference source will increase packet loss rate. Place antenna inside metal shell or there is metal nearby 3 Metal the antenna will cause signal attenuation. RX_EN PIN in emitting devices didn't keep high level will 4 RX_EN PIN reduce the reception sensitivity for responding signal. 功率寄存器设置错误、空中速率设置过高（空中速率越高， 5 Parameter values 距离越近）。 POWER Parameters setting error, the speed set too high. When voltage is under 3.3V, the lower voltage, the less 6 Low voltage transmission power. ★ Heat of module, module will be damaged easily. Check power supply and ensure it's between 2.0V~3.6V. 1 Supply voltage Module will be damaged permanently, if the voltage is over 3.6V 2 Stability ESD 4 5V lEVEL Please check power supply stability, and the power noise. Please insure ESD protect circuit have been applied in mounting process, especially LNA is a easy damaged part. Communication line must be in series with 1k-1.5k resistance if use 5V electrical level.
