About the Iridium-ADC PCB

Iridium-ADC is an open source PCB design by ABillBlakely, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 82.5 × 70 mm, with 111 components from 46 distinct parts.

Other key parts include the ADR434BRZ, OPA207IDR, ADP7105ARDZ, ADP7104ARDZ-5.0 and OPA1612. By type, the board carries 50 capacitors, 34 resistors, 11 ICs, 11 inductors, 4 connectors and 1 diode.

It belongs with the audio, test & measurement and science & space designs in this gallery.

From the project

High performance ADC for audio analysis and scientific measurement.

I recommend that you check out the full design document at docs/Iridium ADC final.pdf.

That very large document contains schematics, gerbers, BOMs, performance metrics, motivations, and analysis.

docs: contains reports and analyses for the project. hardware: contains models and information about the physical structure of the project. ecad: contains the ecad files including schematic and PCB designs. esim: contains electronic simulation files. * src: source files for STM32F446RE microcontroller.
