Description
The module is based on a DS2413 which has two GPIO pins type Open Drain. It allows you to have two GPIO pins controlled from one microcontroller pin. It also works with 1-Wire bus. The dimensions of the board are 16 x 10 mm.
|
The product is compatible with Arduino Auser's guidefor Arduino users. |
You can also connect more circuits DS2413, which in theory can give even 562 trillion GPIOs from one GPIOs of the microcontroller.
Connection
The module has a simple goldpin connectors for self-soldering - raster 2.54 mm, communicates via one microcontroller pin. Description of the specific GPIOs is given in the table.
| Pin | Symbol | Description |
|---|---|---|
| 1 | GND | The ground of the system. |
| 2 | IO |
Pin control. You must connect a pull up resistor 4.7 kω between IO and 5 V. |
| 3 | IOA | Pin And/O type Open Drain. |
| 4 | IOB | Pin And/O type Open Drain. |
The module has a simple goldpin connectors for self-soldering
and the resistor is 4.7 kω.
