Descripción
Placa de conexiones para el transceptor IC RS-485 SP3485
Opera desde un único suministro de +3,3V
Incluye transceptor SP3485 RS-485, condensador de filtro y más
De acuerdo con la directiva RoHS
El SFE Convertidor UART a RS-485 es una placa de arranque para el transceptor IC RS-485 SP3485, que convertirá una transmisión serie UART a RS-485. El SP3485 es un transceptor semidúplex, por lo que solo puede comunicarse de una única manera a la vez, pero puede alcanzar velocidades de transmisión de hasta 10Mbps. Esta placa requiere una cantidad muy baja de energía y puede operar desde una sola fuente de +3,3VDC.
Esta placa incluye el transceptor SP3485 RS-485, el condensador de filtro y los demás componentes que se muestran en el esquema. El fabricante ha dividido la salida RS-485 en tres conexiones diferentes: (1) un conector RJ-45, (2) un terminal de tornillo de 3,55 mm de 3 pines, y (3) un cabezal de paso de 3 pines de 0,1" (2,5 mm); ninguno de estos conectores de salida viene poblados. Este producto reemplaza al BOB-09505 de Sparkfun.
