What's the highlights of RS-485 protocol for UAVs?

HOBBYWING latest H130A 14S ESC introduces the industry's first CAN + 485 dual-bus throttle design. RS-485 is another wonderful protocol that transmits digital signals besides CAN protocol. It has the following highlights for the UAV ESC application:

【Noise Immunity】RS-485 excels in noise immunity, making it ideal for UAV operations in environments with high electromagnetic interference (EMI), such as powerline inspections.

【Long Distance Communication】RS-485 can support long-distance communication up to 4000 feet (approximately 1200 meters), beneficial for large UAVs or those with extensive wiring.

【Differential Signaling】By using differential signaling, RS-485 mitigates the effects of EMI and crosstalk, ensuring reliable data transmission and safer flight even in electrically noisy environments.

【Data Rates】RS-485 supports data rates up to 10 Mbps, which is suitable for most drone applications, including sensor data transmission, control commands, and telemetry.

【Simple Implementation】RS-485 is relatively easy to implement and compatible with standard UART interfaces, facilitating integration into existing UAV systems.

In further, combined with CAN protocol, this dual-bus throttle design ensures more stable signals, enhanced anti-interference, and safer flights under harsh conditions. It is suitable for various drone applications, ranging from industrial inspections to agricultural monitoring.
