The combination of an external circuit and a low-voltage microcontroller occasionally requires a significantly higher power-supply voltage. You can use either an external boost converter to increase ...

When taking measurements from analog sensors located at long distances, voltage drops and noise can affect precision of the readings. Therefore, a voltage-to-current (V/I) module is needed to transmit ...

This article is part of the Ideas for Design Series: Vol. 3, No. 6. Low-voltage microcontrollers generally have been powered from a regulated supply, such as 1.8 to 3.6 V, and have very low current ...

The title says it all – this article describes a microcontroller-compatible current sensor module you can build yourself, using an inexpensive 8-pin chip as an ‘active shunt’ for measuring ac/dc ...

Until recently, a very common problem faced by electronic circuit designers was the difference in supply voltage standards between microcontrollers (e.g. 3.3 V) and peripheral ICs (e.g. 5 V). In order ...
