{"product_id":"rs485-shield-for-oleduino-v2","title":"RS485 Shield for OLEDUINO v2","description":"\u003cp\u003eThis is a fault protected RS485 shield for OLEDUINO-V2, SN65HVD1782 chip used as RS485 transreceiver, designed to survive overvoltage faults such as direct shorts to power supplies, mis-wiring faults, connector failures, cable crushes, and tool mis-applications. The devices are also robust to ESD events with high levels of protection to the human-body-model specification.\u003c\/p\u003e\n\u003cp\u003eThe devices combine a differential driver and a differential receiver, which operate from a single power supply. In the \u003cstrong\u003eSN65HVD1782\u003c\/strong\u003e, the driver differential outputs and the receiver differential inputs are connected internally to form a bus port suitable for half-duplex (two-wire bus) communication. These devices are characterized from–40°C to 125°C. These devices are fully compliant with ANSI TIA\/EIA 485-A with a \u003cstrong\u003e5V supply\u003c\/strong\u003e and can operate with a \u003cstrong\u003e3.3V supply\u003c\/strong\u003e with reduced driver output voltage for low power applications.\u003c\/p\u003e\n\u003cp\u003eIt can be paired with the \u003ca href=\"https:\/\/www.electronics-lab.com\/project\/oleduino-v-2\/\"\u003eOLEDUINO-V2\u003c\/a\u003e, enabling the creation of a miniature RS485 interface with OLED display.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePower Supply 5V (Supports 3.3V)\u003c\/li\u003e\n\u003cli\u003eScrew Terminal for RS485 Connections\u003c\/li\u003e\n\u003cli\u003ePCB Dimensions 25.4 x 25.4 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eConnections\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCN1: Pin 1 = RS485 Channel B, Pin 2 = RS485 Channel A\u003c\/li\u003e\n\u003cli\u003eCN2: Optional\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eArduino vs RS485 Connections\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDigital Pin D10 = RO\/Receiver Output\u003c\/li\u003e\n\u003cli\u003eDigital Pin D02 = RE\/Receiver Enable\u003c\/li\u003e\n\u003cli\u003eDigital Pin D03 = DE\/Transmitter Enable\u003c\/li\u003e\n\u003cli\u003eDigital Pin D11 = DI\/Data Input\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"dotfry","offers":[{"title":"Default Title","offer_id":47247474294956,"sku":"C119","price":12.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0757\/6436\/7532\/files\/C119A.jpg?v=1789817174","url":"https:\/\/dotfry.com\/products\/rs485-shield-for-oleduino-v2","provider":"dotfry","version":"1.0","type":"link"}
