Measuring Supply Current Accurately

The current measurement mode in most multimeters is sufficient for many applications.  However, when measuring the supply current of loads that draw current infrequently in small bursts, it becomes difficult to measure the real, average current consumption accurately due to the slow sample rate of the multimeter.  Many wireless telemetry nodes present exactly such a […]

Data Acquisition Arduino Shields

After developing several products focused on data acquisition, like the MRBW-RTS and a few currently in development like the MRB-DCCM (DCC Meter) and MRBW-DAQ (Data Acquisition node), we realized some of the ICs used in those designs would be useful on their own.  To enable rapid development with these ICs, a series of ArduinoTM shields […]
