Monitor voltage and current with the Tiny V/A Meter
https://www.electronics-lab.com/monitor-voltage-current-tiny-v-meter/
Measuring voltage and current is an important part of the development process for any hardware product. Especially when developing a low power device, the knowledge of how much power the device is drawing at each mode of its operation is critical to the correct estimation of its battery life. While voltage can be measured in […]
DIY voltage and current reference
https://www.electronics-lab.com/diy-voltage-current-reference/
Petteri Aimonen designed and built his own voltage and current reference: When developing a data acquisition system, I ran into a need of having fairly accurate current reference to compare against, 0.1% accuracy or better. This is not a particularly high standard, but unable to find a suitable device in my price range, I chose […]

The company has also upgraded their Kickstart measurement software to version 2.0. Keithley has long been a dominant provider in the 6½-digit DMM market. With the DMM6500 and DAQ6510, the company looks forward […]
Low-side I/V sensing IC, with internal power calculation
https://www.electronics-lab.com/low-side-iv-sensing-ic-internal-power-calculation/
Maxim Integrated has posted details of the MAX44299, a low-side current, voltage, and power monitoring circuit that provides an analogue output current proportional to the measured current, voltage, and the internally calculated instantaneous power. The power monitor offers high precision and integration in tiny size. Instantaneous power is calculated internally by multiplying the load current […]
How-to use PWM to Generate Analog Voltage in Digital Circuits
https://www.electronics-lab.com/use-pwm-generate-analog-voltage-digital-circuits/
Maurizio @ emcelettronica.com tipped us with his latest article on how to generate analog voltages using a microcontroller. Many times, designers are faced with the need of generating analogue or analog voltage levels in purely digital circuits. Although the market provides today a very broad range of dedicated digital-to-analogue converters, putting such a device in the […]
USB Power Meter
https://www.electronics-lab.com/usb-power-meter/
Daniel Grießhaber @ hackaday.io has published his build of a USB power meter. His device is based on ATTiny 85 mcu and 0.96″ OLED Display and is able to measure voltage, current and power output from USB port. Since USB has become more and more a power delivery standard, it would be nice to have a convenient way to […]
