Module features:
1. Brand new original industrial-grade chip, ultra-long-distance transmission can reach thousands of meters.
2. ESD protection with plus or minus 15KV
3. The chip has a limited slew rate driver to reduce EMI and reduce signal reflection caused by improper terminal matching cables, so that the error-free signal transmission rate is as high as 500Kbps.
4. Receiver input impedance with 1/4 unit load, supports multi-machine communication, and allows connection to the bus with no more than 128 devices.
5. The operating temperature of industrial-grade chips can reach -40°C to 85°C.
6. This module can be hot-swapped, and there will be no signal plugging caused by hot-swapping of other 485 chips.
7. The power supply uses SMD tantalum electrolytic capacitors, and uses double capacitors for high and low frequency power supply filtering
8. Using dual transient suppression diodes, excellent overvoltage protection performance
9. Use 10Ω current protection resistor, patch design to improve 485 signal integrity
10. With terminals and welding lead holes, it is convenient to debug and finalize the wiring, and the welding leads can improve signal reliability
11. All RS485 and TTL signals are routed on one side to ensure signal quality and improve signal integrity
12. Spread copper on a large area to prevent signal interference
13. With 2.54 pitch hole plate welding holes, it is convenient for your secondary development
14. It has M3 screw holes that are quite commonly used at present, which is convenient and reliable to install
15. With 120Ω termination resistance, short-circuit R16 to enable termination resistance
16. With power and RXD, TXD signal indicator lights, you can have a panoramic view of the transceiver status
17. The angled pins are led out for easy testing
18. Support 3.3V and 5V signal control, strong compatibility
