Now I can access them again on-line – how good is that? Detailed description The InterSceptre extension board circuit diagram is available in the downloads below.
So what has InterSceptre got to offer? Given that the InterSceptre can operate from 3. The InterSceptre operates from 3. One important detail not to be overlooked: During application development, the Sceptre will be connected to a computer via a USB cable connected either directly to the Sceptre, or via the InterSceptre.
The shells fix together using a pair of screws. The gain is adjusted using turn presets. Even though the Sceptre offers lots of peripherals, it only has fifty pins, which means that certain functions are obliged uuni share pins. Follow project Add a comment.

Just what I was waiting for – brilliant!
The InterSceptre 
This can be handy where the Sceptre is being powered from a battery. So below you can find the Eagle files for the circuit diagram and PCB, the components list.
The level shifter used comes from a Philips or NXP application note. 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. Topics ElektorMagazineCollection. Treasure trove of electronics information I first dipped my toes into electronics engineering via Elektor and I have kuni greatly from it over the years. If you use a different microcontroller board without its own battery, a button cell holder is available on the InterSceptre.
In any case, there are very few applications that would require everything to be used at once. 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.

In this way, InterSceptre has four analogue outputs, available on the way sub-D connector K So take care how you fit the regulator! If unity gain is all you need, you can omit these and connect the inverting inputs directly to the outputs.
