Feature:
- With positive and negative 15KV ESD protection, the chip has a limited slew rate driver to minimize EMI and reduce signal reflections caused by improper terminal matching cables, thereby enabling error-free signal transmission rates up to 500Kbps.
- The input impedance of the receiver with a 1/4 unit load supports multi-machine communication, allowing connection to a bus of up to 128 devices.
- Using 10 current protection resistors, patch design to improve 485 signal integrity.
- With terminals and welding lead holes, convenient debugging and final fixed wiring, welding leads can improve signal reliability.
- Welding holes with 2.54 pitch holes for easy secondary development.With M3 screw holes that are quite commonly used at present, easy and reliable installation.
- With 120 termination resistance, short-circuit R16 to enable termination resistance.With power supply and RXD, TXD signal indicator, the receiving and sending status can be seen at a glance.
- Angled pin leads for easy testing, support 3.3V and 5V signal control, more compatible.
