HC-12 433 SI4463 Wireless Serial Module

Description

• Frequency: Operates in the 433 MHz ISM (Industrial, Scientific, and Medical) band, which allows for relatively long-range communication under the right conditions.
• Transceiver Chip: Utilizes the SI4463 chip, a highly integrated wireless ISM band transceiver from Silicon Labs, known for its excellent performance and reliability.
• Serial Communication: Supports transparent serial communication, enabling point-to-point or multi-point communication between devices as if they were connected via a physical serial cable.
• Operating Modes: Can operate in various modes, including FU3 (fixed transmission), FU4 (fixed transmission with control), and FU5 (PTT control transmission). These modes determine how the module handles data transmission and reception.
• Output Power: The module typically allows users to adjust the output power within a certain range, enabling control over the communication distance and power consumption.
• Antenna: Requires an external antenna for proper communication. The type and quality of the antenna significantly impact the communication range.
• Voltage Range: Supports a wide voltage range, making it compatible with different microcontroller systems and power supplies.
