The XL4432-SMD wireless module is designed by our company using Silicon Labs\' Si4432 B1 Edition chip, which is a complete, compact, low-power wireless transceiver module. SI4432 One of Silicon Labs EZRadioPRO series ISM band wireless chips introduced by Silicon Corporation in 2009 is a highly integrated wireless ISM band transceiver chip that operates over the 240-960 MHZ band with extremely high reception sensitivity (- 121 dBm) and the maximum output power can reach +20 DBm, which to some extent to meet the RF signal amplification development difficult problem. And then the maximum power setting conditions, the open communication distance of up to 1000 meters. Known as "through the wall of the king," said. The module integrates all RF related functions and devices, users do not need to understand the relevant knowledge of the radio, you can use this module can easily develop stable and reliable wireless related products.
The XL4432-SMD is based on Silicon\'s original factory-specific information and is designed to feature the most versatile SI4432 features. Module devices are all used Murata high-frequency specifications of the inductor capacitor, crystal 10ppm high-precision specifications to ensure that the module\'s wireless characteristics are fully reflected. From Shenzhen professional OEM processing plant using high-precision placement machine environmentally friendly lead-free solder processing, all modules have been professional equipment testing, module consistency and stability are fully protected. SPI interface, small size, stamp hole interface to facilitate the embedded design, fully expand the distance, so that your equipment performance to a higher level.
Shipping list XL4432-SMD wireless module one Silver plated 433M antenna one
1, the frequency range: 410-440M (antenna match the best range, and the domestic free ISM band)
2, the sensitivity: up to -120 ~ -121dBm (1.2Kbps)
3, the maximum wireless transmission power output: 20dBm (1.2Kbps, 433M)
4, the data transfer rate: 0.123-256kbps
5, modulation mode: FSK, GFSK and OOK
6, power supply: 1.8-3.6 V
7, ultra-low power consumption in the power mode is 10nA (4.21ms), in standby mode 300nA, sleep mode 600nA (1.21ms); receive current 18.5mA, the maximum emission current 80mA (200us).
8, digital received signal strength indicator (RSSI)
9, the timer wake-up function, wireless wake-up function (WUT)
10, antenna automatic matching and two-way switch control
11, can be configured packet structure
12, pre-sync signal detection
13, 64 bytes send and receive data register (FIFO)
14, on-chip integrated low battery power detection
15, on-chip temperature sensor and 8-bit analog-to-digital converter
16, the operating temperature range: -40 ~ +80 ° C (temperature characteristics and product consistency is much better!)
17, integrated voltage regulator
18, frequency hopping function
19, power on reset function
20, built-in crystal error adjustment function
21, the chip automatically calculates and verifies CRC-16, and supports three 16-bit CRC polynomials
22, up to 4 bytes of the head can be used at the receiving end using the header filter, which can be set by address to receive.
1, the antenna must be open around, away from the battery, metal, etc., the antenna around the PCB is prohibited copper, if necessary, PCB and antenna overlap part of the hollow or punch.
2, when the design of the product on the metal shell, metal cabinets, must be used Antenna feeder The signal from the antenna leads to external SMA antenna Or sucker antenna, otherwise the signal is shielded by the metal shell so that the distance greatly reduced, requiring distance, you can use high-gain antenna.
3, power supply design. Power is the heart of the entire system, the design should be considered. Si4432 wireless module recommended operating voltage 3.3V, transient current can provide more than 200mA.
4, using DCDC, LDO buck, but also consider the impact of ripple and surge current. Ripple can be connected to the module power supply where the LC network processing; inrush current can be connected to a large capacitor.
5, if the use of battery-powered, should consider the battery transient current is sufficient, it is recommended to use lithium batteries Ni-MH battery is not recommended with dry batteries.
6, the software design, should try to use packet communication, communication set the lower the rate, the farther away.
7, when using the DEMO program outside the communication rate of communication, the application of parameter calculation tool to recalculate the communication parameters. And according to their product communication requirements, appropriate adjustments.
