MAX3485 Module TTL To RS485 Module MCU Development Accessories
All the chips we guarantee are brand new imported industrial-grade chips, which can reach a distance of thousands of meters.
The ESD protection with plus or minus 15KV
3, 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.
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.
5, industrial-grade chips working temperature can reach to 40 ° to + 85 °.
6, this module can be hot plug, no other 485 chip heat plug is dead phenomenon.
The power supply is used with the tantalum electrolytic capacitor, and the double capacitor is used for high low-frequency power filtering
Using double transient suppression diode, the over-voltage protection performance is excellent
9, 10 Ω current protection resistance, patch designed to improve 485 signal integrity
It has terminals and welded lead holes, easy to debug and fixed wiring, and welding leads can improve the reliability of the signal
The RS485 and the TTL signal are all single-sided, ensuring the quality of the signal and improving signal integrity
Spread copper over large areas to prevent signal interference
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
15, have 120 Ω termination resistor, can make short sub R16 can termination resistor
16, with power supply and RXD, TXD signal, receiving and receiving
The Angle pin is introduced to facilitate testing
Support 3.3 V and 5V signal control and compatibility
