The WS8472DLS is a high-performance, multi-band LoRa serial module designed and manufactured by by Silent Smart Technology Co., Ltd..It features long communication distance and extremely low current consumption in low-power mode. The module features a compact SMD, measuring 26 × 16 mm with a 1.27 mm pin pitch
High performance features: 1. Onboard low ripple rejection ratio (PSRR) LDO effectively reduces the impact of power supply on RF performance; 2. High-performance RF filter added to the transmit link of the WS8472DLS module effectively suppresses high-order harmonics; 3. SAW + LNA + SAW combination added internally to the WS8472DLS module effectively suppresses out-of-band interference while further improving receiver sensitivity; 4. The WS8472DLS module uses a high-precision, high-stability, low-temperature drift, wide-temperature compensated active crystal oscillator (TCXO); 5. All RF links of the WS8472DLS module use high-Q wire-wound inductors; 6. ESD electrostatic protection added to communication and power supply, effectively protecting the IC; 7. Antenna port has ESD protection circuitry, meeting the IEC 61000-4-2 testing standard.
Supports the unlicensed ISM 433MHz band and the 470MHz meter reading band.
It adopts LoRa spread spectrum technology, which has strong anti-interference performance and long communication distance.
It allows users to set their own communication keys, which cannot be read, greatly improving the confidentiality of user data.
Supports a maximum transmit power of 158mW (approximately 22dBm).
Adding RF filter in the transmit link for effective higher-order harmonic suppression.
Adding SAW + LNA + SAW to the receiver link reduces out-of-band interference and increases receiver sensitivity.
Onboard high-precision, temperature-compensated crystal oscillator (TCXO) for exceptional frequency stability.
Add ESD protection to communication ports, power ports, and antenna ports.
Supports AT command configuration
Supports Modbus programmable register read/write operations, allowing for flexible customization of product functions.
It supports over-the-air wake-up, i.e., ultra-low power consumption, and is suitable for battery-powered applications.
Supports transparent transmission and fixed-point transmission. Broadcast transmission, Channel monitoring, wireless relay and other functions
