Ultra small wireless SI4432 Long Distance Wireless Transceiver Module

Ultra small wireless module SI4432 Long Distance Wireless Transceiver 1000 meters wireless module (transmitter and receiver) based on the SI443 chipset. Ranges up to 1000 meters can be achieved! Easy connection to Arduino etc.

Ultra small wireless SI4432 Long Distance Wireless Transceiver Module is a Ultra-thin small,PI connection,Stamp hole interface facilitate embedded design,stable performance. Module integrates all RF-related features and components. User even does not need to understand the knowledge of radio, you can easily develop a stable and reliable performance of wireless-related products with this module.

Features:

• Frequency range: 410-440M (antenna matching the best range, and the domestic free ISM band)
• Sensitivity: up to -120 ~ -121dBm (1.2Kbps)
• Maximum output power of wireless transmitter: 20dBm (1.2Kbps, 433M)
• Data transfer rate: 0.123-256kbps
• Modulation mode: FSK, GFSK and OOK
• Power supply: 1.8-3.6 V
• Ultra-low power consumption in the power-down mode 10nA (4.21ms), in standby mode 300nA, sleep mode 600nA (1.21ms); receive current 18.5mA, the maximum emission current 80mA (200us).
• Digital received signal strength indicator (RSSI)
• Regular wake-up function, wireless wake-up function (WUT)
• Antenna automatically matches and two-way switch control
• Packet structure can be configured
• Pre-synchronization signal detection
• 64 bytes Transmit Data Register (FIFO)
• On-chip low battery detection
• On-chip temperature sensor and 8-bit analog-to-digital converter
• Operating temperature range: -40 ~ +80 ° C (temperature characteristics and product consistency is much better!)
• Integrated voltage regulator
• Frequency hopping function
• Power-on reset function
• Built-in crystal error adjustment function
• Chip automatically calculates and checks CRC-16, and supports three 16-bit CRC polynomial 22, up to 4 bytes of the first frame head available at the receiving end of the use of the first frame of the first filter, which can be set up by address to receive

Pinouts:

• GND: Power Ground
• GPIO0: Internal has connected the emission control module feet
• GPIO1: Internal has connected the receiving control module feet
• GPIO2: Connect the the chip GPIO2 pins directly
• VCC: Connect power positive 3.3 V
• SDO: 0 ~ VDDV digital output, provide the internal control of the register serial back to read function
• SDI : Serial data input. 0 ~ VDD V digital input. The pins for the 4 wire serial data serial data flow bus.
• SCLK: A serial clock input. 0 ~ VDDV digital input. The pins provides the 4 wire serial data clock function
• nSEL Serial interface selection/enable input pin. 0 ~ VDDV digital input.The pins for the 4 wire serial data bus provides the choice/make can function, this signal is used to indicate a read/write mode.
• nIRQ :Interrupt output pins
• SDN : Close input pins. 0 ~ VDDV digital input. In addition to shut down all the mode mode SDN = 0. When SDN = 1 chip will be completely shut down and the content of the register will be lost.v
• GND: Power Ground
• ANT: Pick up the coaxial antenna 50
• GND: Power Ground
