It converts the UART interface of open-source hardware like the ESP32 Arduino to an RS485 interface. Its dedicated design automatically switches data transmission, eliminating the need to remove the module during programming. It's an ideal IoT debugging tool.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eR485P32 ESP32 Arduino Specific RS485 converter\u003cbr\u003e\u003cbr\u003e\n  Working voltage: DC 3.3-5V\u003cbr\u003e\n  Working Current: 5-40MA\u003cbr\u003e\n  TTL level: DC 3.3V\/5V\u003cbr\u003e\n  ESD protection:±20KV\u003cbr\u003e\n  True Fail-Safe Receiver\u003cbr\u003e\n  Anti-surge protection: 6.5V\u003cbr\u003e\n  Allow Up to 256 Transceivers on the Bus\u003cbr\u003e\n  Terminal spacing: 3.96mm.\u003cbr\u003e\n  Terminal Blocks: Wire Range 26-16AWG, Strip Length 3.96mm, Metric M2\/M2.5 Slotted Screws.\u003cbr\u003e\n  Operating temperature : -40-85℃\u003cbr\u003e\n  Size : 34x17x4.0mm(No Terminal),34x17x12mm(With Terminal)\u003cbr\u003e\n  Weight :2.3g(No Terminal),5.3g(With Terminal)\u003cbr\u003e\u003cbr\u003e\n  Features:\u003cbr\u003e\n  Does not affect USB programming\u003cbr\u003e\n  Automatic direction switching\u003cbr\u003e\n  Automatic baud rate: 100-128000BPS\u003cbr\u003e\n  Automatic parity: None\/ODD\/EVEN\u003cbr\u003e\n  Automatic stop bits: 1\/1.5\/2\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003ePin description:\u003cbr\u003e\n  VCC: Power Supply +(3.3-5V)\u003cbr\u003e\n  GND: Power Supply -\u003cbr\u003e\n  RXD: TTL receive port\u003cbr\u003e\n  TXD: TTL transmit port\u003cbr\u003e\n  GND : RS485 BUS construction site end (usually can not be connected)\u003cbr\u003e\n  A+ : RS485 BUS A+\u003cbr\u003e\n  B- :RS485 BUS B-\u003cbr\u003e\u003cbr\u003e\n  Application\u003cbr\u003e\u003cbr\u003e\n  For Arduino UNO MEGA2560 NANO Pro MINI etc.\u003cbr\u003e\n  For ESP32 S3 C3 C6 etc.\u003cbr\u003e\n  For Raspberry Pi Original PI etc.\u003cbr\u003e\n  RS485 Temperature and humidity sensor\u003cbr\u003e\n  PTZ Camera\u003cbr\u003e\n  MODBUS RTU IO\u003cbr\u003e\n  RS485 Relay\/Switch\/Sensor\u003cbr\u003e\n  Automated Manufacturing line\u003cbr\u003e\n  Wifi to RS485(ESP8266\/ESP32)\u003cbr\u003e\n  Bluetooth to RS485(HC-05\/HC06)\u003cbr\u003e\n  Wireless Module to RS485(HC-11)\u003cbr\u003e\n  Ethernet to RS485( Ethernet TTL Module)\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003e\u003cimg src=\"https:\/\/publish-cos.mabangerp.com\/upload\/privatepublish\/ali\/900096\/20251029\/176169495081954900487.jpg\" alt=\"\" data-href=\"\" style=\"\"\u003e\u003cbr\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0858\/1700\/0192\/files\/176169495077700000709.jpg?v=1791776073\" alt=\"\" data-href=\"\" style=\"\"\u003e\u003cbr\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0858\/1700\/0192\/files\/176169495092706400478.jpg?v=1791776075\" alt=\"\" data-href=\"\" style=\"\"\u003e\u003c\/p\u003e","brand":"eletechsup","offers":[{"title":"No Terminal","offer_id":50580946288896,"sku":"R485P32_NO","price":3.69,"currency_code":"USD","in_stock":true},{"title":"With Terminal","offer_id":50580946321664,"sku":"R485P32_PIN","price":4.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0858\/1700\/0192\/files\/900096202610121131566acc54acc5381.jpg?v=1791776071","url":"https:\/\/www.eletechsups.com\/products\/r485p32-esp32-rs485-interface-expander-smart-home-iot-diy-master-slave-module-485-to-ttl-232-converter-for-solar-inverters-smart-meters","provider":"eletechsup","version":"1.0","type":"link"}
