RJ11turn6PinInterface board (will beRJ11 DS9097/DS9490Port conversion6pinBend needle
The circuit board is used for the1-WireAdapterRJ11The output port is transferred to6PinBend pin output, DS9097/DS9490Output port.6pinThe output signal is listed on the circuit board, and the user can connect the board to the board of the circuit board.1-WireDevice. The circuit board is also provided with twoTO-92One of them is a parasitic power supply mode, and the other is a separate power supply mode.(IfRJ11Can provide power supply), can be connected asDS18B20etc.TO-92Packaged device. The back side of the plate is respectively provided with aTSOC-6as well asSOT-23Two kinds of package pads, and lists the package pin definitions(AGND, oneI/O)Users can weldTSOC-6as well asSOT-23Packaged device for testing. If the user uses the microcontroller to design1-WireHost, you can not connectRJ11Cable, directly to the6pinThe corresponding signal of the curved needle is connected with the single chip microcomputer, and the corresponding device is tested on the package provided by the interface board. The interface board can be used forTO-92Package of small batch device programming, if you need a lot of programming, it is recommended to use a dedicated socket, because the interface board is mainly used to test and interface conversion. characteristic Test chart: DS9490 MaximConnection diagram of the adapter plate:
