3pcs MAX3485 TTL To RS485 Module MCU Development Converter Module Board Accessories
1.The ESD protection with plus or minus 15KV
2.Chip driver is set rate, reduce EMI, and reduce caused by the improper matching cable terminal signal reflection, making the error-free signal transmission rate is as high as 500 KBPS.
3.A receiver that has a unit load of 1/4 is an impedance that supports multiple communication and allows for a bus that is connected to no more than 128 devices.
4.This module can be hot plug, no other 485 chip heat plug is dead phenomenon.
5. The power supply is used with the tantalum electrolytic capacitor, and the double capacitor is used for high low-frequency power filtering
6.Using double transient suppression diode, the over-voltage protection performance is excellent
7.10 Ω current protection resistance, patch designed to improve 485 signal integrity
8.It has terminals and welded lead holes, easy to debug and fixed wiring, and welding leads can improve the reliability of the signal
9.Spread copper over large areas to prevent interference,The RS485 and the TTL signal are all single-sided, ensuring the quality of the signal and improving signal integrity
10.It has 2.54 interval hole welded hole for your secondary development,It has the M3 screw hole which is quite commonly used now, and the installation is convenient and reliable.
11. Support 3.3 V and 5V signal control and compatibility, and working temperature: 40 ° to + 85 °.
