- Single chip computer, RS485 TTL conversion module, UART 485 conversion serial port, level transmission, hardware flow control A single one in the entire network, 3.3V and 5.0V power supply, RS485 signal is perfectly compatible with the automatic flow control module. A RXD, TXD indicator light, monitors the send and receive status. Uses 2.54 standard, easy secondary development. Color: blue Material: metal Operating Temperature: -40 degrees Celsius ~ 85 degrees Celsius. Size: 42.8mm x 15.22mm x 0.8mm. Absolutely adopts imported, industrial design, strong anti-interference ability, at the same time a more effective lightning protection, 485 can be used in industrial and field harsh environments. (With 850 meters of 2 x 1.5 cable for testing, it is recommended to use within 800 meters, more than 800m, please add additional repeaters.) Uses 0.8mm thick half-hole processing technology. , can be easily used as a child motherboard, can also be used welding terminals. With 120 European matching resistance, can short R0 can match a resistance, suggested it short response for long-distance transport. Supports multi-machine communication, allowed to support up to 128 devices on the bus. The module can be hot-plugged, there will be no other 485 hot-plug phenomenon of signal switching to death. Large copper plating area, prevents signal interference. Package Contents: 1 x TTL to RS485 Adapter Only the above package content, other products are not included. Note: Light shooting and different displays may cause the color of the item in the picture to be slightly different from the real thing. The allowed measurement error is +/- 1-3 cm.
