Multi-pole industrial relays provide more possibilities

As we know, a relay is a very versatile component, able to realize also various “sequential” circuits, when for example by switching one relay we´ll switch on a target device and at the same time we´ll enable (or disable) switching of another relay. In these case, it´s an often demand for a relay to have a sufficient number of poles. Majority of such “logic” circuits can be realized even with a common 1-2 p ...

LSF0204 breakout board: a bidirectional, multi-voltage level converter!

I needed a small, fast and reliable multi-voltage level translator (mainly for connecting ESP8266 boards to the Arduino, got tired of resistor networks pretty quickly) so I built a breakout board for TI’s LSF0204(D). Datasheet and info here. The LSF0204 is a nice little chip. It can translate up to 4 signals to and from the following values: 1.0 V ↔ 1.8/2.5/3.3/5 V. 1.2 V ↔ 1.8/2.5/3.3/5 V. 1.8 V ↔ 2.5/3.3/ ...
