RS485 module to TTL with Isolation Single Chip Microcontroller UART Serial Port

RS485 module to TTL with Features:

• Power Versatility: Perfectly compatible with both 3.3V and 5.0V power inputs.
• Superior Construction: Equipped with an imported industrial-grade chip, this module stands strong against external disturbances. It also boasts a proven lightning protection design.
• Exceptional Range: Achieves a transmission distance of up to a kilometre, tested with 850m using a 2*1.5 cable. For optimal performance, usage within 800 meters is recommended. For anything beyond, consider adding a repeater.
• Design Flexibility: Crafted with a half-hole process, the 0.8mm-thick plate can effortlessly function as a composite or be used for terminal welding.
• Status Indicators: Comes with RXD and TXD signal lights, providing a comprehensive view of the sending and receiving statuses.

Additional RS485 Module to TTL Highlights:

• Advanced Protection: Designed with heightened focus on lightning protection and anti-interference. When connected to the earth during long-distance transmissions, the module’s “Earth” ensures superior interference resistance. However, for indoor short-range use, earthing isn’t necessary.
• Developer-Friendly: The standard 2.54 spacing design ensures ease of development integration.
• Optimized Transmission: Features a 120Ω matching resistance. For best results during long-distance transmissions, the R0 can be short-connected to match the resistance.
• Multi-Machine Compatibility: Supports communication with up to 128 devices on a single bus.
• Hot Plug Capable: Unlike many other 485 chips, this module allows for hot-swapping without signal interference.
• Enhanced Signal Integrity: The module’s extensive copper layout minimizes signal interference, ensuring clear data transmission.
