About the Sensing & Power management PCB

Sensing & Power management is an open source PCB design by MartinBraquet, published on GitHub under the MIT license. It is a 2-layer board measuring 143 × 82 mm, with 32 components from 23 distinct parts.

Other key parts include the OPA2834IDGKR, AEM10941 and 929834-05-08-RK. By type, the board carries 5 capacitors, 4 resistors, 3 ICs, 3 jumpers, 2 connectors and 2 inductors.

It belongs with the audio and sensors designs in this gallery.

From the project

Design of an ultra-low-power energy-harvesting audio sensor for ecosystem monitoring (June 2020).

Here are the source files of my Master's thesis at UCLouvain (June 2020).

It includes all the simulations required for this work: Audio processing: C code for the microcontroller and Matlab code to process the data (plot the graphs) received from the board BOM: Excel file with the bill of materials IV mic: Matlab code to plot the IV curves (current/voltage) of different microphones Microcontroller: Wisebatt simulation to provide a rough estimate of the whole system power consumption Microphone: LTspice and Matlab codes for the microphone/AFE subsystem (AC and noise) PCB: KiCad and Eagle…
