The InterSceptre extension board circuit diagram is available in the downloads below. If SDA is at 3. For microcontrollers with more UARTs, the ports are available to them. Now I can access them again on-line – how good is that? Not to worry even if the switches have been set to the 3. So what has InterSceptre got to offer? In this way, InterSceptre has four analogue outputs, available on the way sub-D connector K But the information and jumi descriptions of the circuits and how they function are a very practical way to see the real world of electronics after learning from the textbooks.

Topics ElektorMagazineCollection. So take care how you fit the regulator! Jkni opted for male connectors to ensure compatibility with PC serial ports. On the microcontroller side, the four ports are connected to terminal strips that let you choose which will be used with a given COM port.

Each of the signals is protected by a small current-limiting resistor. So below you can find the Eagle files for the circuit diagram and PCB, the components list.

This will save you a bit of money. The Internet module is powered from 3.

Not all of the information is current. The gain of the output stages is adjustable a bit too much, really, for reasons of simplicity and they are powered from 5 V, at all times, which means a 3. If unity gain is all you need, you can omit these and connect the inverting inputs directly to the outputs. The InterSceptre PCB has been designed to fit into a case which, in addition to providing protection, also lets you use the elektoe directly within a final application without its looking like a bodge.

The InterSceptre [100174]

As already mentioned above, the InterSceptre itself does not produce the 3. Two other switches offer the possibility of connecting terminating resistors if needed. Follow project Add a comment.

Even though the Sceptre offers lots of peripherals, it only has fifty pins, which means that certain functions are obliged to share eelektor.

I lost most of my collection to water damage when I last moved so this is so appreciated. For software please refer to the Sceptre page. Given the number of ports implemented, the circuit is pretty huge, but easy enough to follow.

Treasure trove of electronics information I first dipped my toes into electronics engineering via Elektor and I have profited greatly from it over the years.

This can be handy where the Sceptre is being powered from a battery. Well, quite a lot, actually: The MIDI port consists of just an input and an output. If you 210 a different microcontroller board without its own battery, a button cell holder is available on the InterSceptre. In this situation, the Nuni port can provide all the power. Thank you Thank you so much, it was a fantastic job.

The gain is adjusted using turn presets. All this on a PCB that fits exactly into an attractive, 20110 case measuring 18 x 20 x 5. Note to that InterSceptre does not offer a 3. One important detail not to be overlooked: One minor drawback with the Sceptre is the absence of the battery voltage on the extension connectors — but it does have its own battery.

Like the Sceptre, InterSceptre is also an open-source, open hardware project. These may adversely affect the maximum communication speed possible, so if the whole circuit can run off 3.

Elektor articles – PolyValens

This IC is compatible with 3. The chip itself adds the missing four MSBs, hence its address is xxx, where xxx represents the position of the three switches 0x20 to 0x27 in hex.

One issue I did retain for posterity was Elektor Book 75 which I could not locate in the English archive listing https: The InterSceptre operates from 3. Note eoektor it is highly inadvisable to hot connect or disconnect equipment to this port.

You can connect a switch to JP9 to let you turn off the Sceptre power.

Detailed description The InterSceptre extension board circuit diagram is available in the downloads below. Thanks for the effort it took to get this all together. The other diodes D2, D5, and the other D2 in the Sceptre take care of the rest. In this way, it is possible to connect a 3. In any case, there are very few applications that would require everything to be used at once.

An important addition to the Archive An important addition to the Archive. We have made provision for two possible regulator types a or a low-voltage-drop stylewhich, for some unknown reason, do not have the same pin-outs.

For applications where no USB connection is possible or necessary, or if more power is needed than can be supplied by a USB port, a 5 V supply is available via the InterSceptre.

Some of the projects are almost unbuildable.
