RS422 module transfers between TTL MAX490 TTL module

1. RS422 interface, two-way communication. A b y z ultra far transmission 1000M
2. The module has 15kV ESD protection.
3. Add 10 ohm current limiting protection resistor on the board.
4. The module has TVS diode. Anti lightning, anti peak voltage.
5. The module has 120 ohm terminal resistance, which can effectively reduce the echo interference of long-distance communication.
6. There are power indicator and data transceiver indicator. You can see the status of the data.
7. The TTL side of the module uses 5V DC power supply, and RXD TXD is compatible with 5V logic signal.
8. The module adopts the original imported MAX490 chip, and its stability and communication speed are far higher than those of domestic products, up to 2.5mbps
9. Module size: 5.0cm * 2.7cm
