SparkFun Transceiver Breakout - RS-485

9.95 €9.95

Availability: Retired

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 +3.3VDC 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 componentsOperates from a single +3.3V supplyInteroperable with +5.0V logicRS-485 input/output broken out to RJ-45 connector, 3.5mm screw terminal, and 0.1" pitch headerDriver/Receiver Enable connected to RTS line-7V to +12V Common-Mode Input Voltage RangeAllows up to 32 transceivers on the serial busDriver Output Short-Circuit ProtectionDimensions: 0.9x1.0"Documents:SchematicEagle FilesDatasheet (SP3485)GitHub (Design Files)
