Bomanz
About the Bomanz PCB
Bomanz is an open source PCB design by kelu124, published on GitHub. It is a 2-layer board measuring 65 × 30 mm, with 15 components from 11 distinct parts.
Other key parts include the ADC08200CIMT/NOPB. By type, the board carries 5 capacitors, 3 diodes, 2 connectors, 2 resistors, 1 IC and 1 inductor.
From the project
High-speed pHAT
I've always needed a small upgrade to the existing raspberry ADC extensions, would love something in the 20-Msps range. Let's see if one can do it! Never tried smd, and thinking of using both smd and dip.. interesting learning curve ahead.
I've tried 3 different versions, increasing in complexity
An older version using a CA3306 can be found as well: going around 10Msps, 6 bits. DIP based components. A possibly fast version of a 8 bit AD08200 ADC is available, going up to 12Msps. * The latest 24Msps pHAT

Bomanz: common questions
How big is the Bomanz PCB?
The Bomanz measures 65 × 30 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Bomanz?
15 components, from 11 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Bomanz design files?
From the kelu124/bomanz repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Bomanz design in my own project?
The repository has no license, so all rights stay with kelu124. Use it as a reference, and ask the author before reusing the design.
