RS485 - Transceiver Breakout
Description: This is a breakout board for the SP3485 RS-485 transceiver IC£¬ which will convert a UART serial stream to RS-485. The SP3485 is a half-duplex transceiver£¬ so it can only communicate one way at a time£¬ but it can reach transmission speeds of up to 10Mbps. This board requires a very low amount of power and can operate from a single +3.3V DC supply. This breakout board includes the SP3485 RS-485 transceiver£¬ filter capacitor£¬ and other components shown on the schematic. We've broken out the RS-485 output to three different connections: (1) an RJ-45 connector£¬ (2) a 3-pin 3.55mm screw terminal£¬ and (3) a 3-pin 0.1" pitch header; none of these output connectors come populated. Features: Fully equipped with SP3485 RS-485 transceiver and supporting components Operates from a single +3.3V supply Interoperable with +5.0V logic RS-485 input/output broken out to RJ-45 connector£¬ 3.5mm screw terminal£¬ and 0.1" pitch header Driver/Receiver Enable connected to RTS line -7V to +12V Common-Mode Input Voltage Range Allows up to 32 transceivers on the serial bus Driver Output Short-Circuit Protection
