Adc
About the Adc PCB
Adc is an open source NXP PCB design by lucia3e8, published on GitHub. It is a 2-layer board measuring 70 × 44.6 mm, with 10 components from 9 distinct parts.
Its main chip is the TEENSY4.1, from the NXP family. Other key parts include the ADS131M08QPBSRQ1 and MCP1700X-330XXTT. By type, the board carries 4 capacitors, 3 ICs, 2 connectors and 1 inductor.

Adc: common questions
What microcontroller does the Adc use?
The Adc is built around the TEENSY4.1, from the NXP family.
How big is the Adc PCB?
The Adc measures 70 × 44.6 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Adc?
10 components, from 9 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 Adc design files?
From the lucia3e8/emgsvm repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Adc design in my own project?
The repository has no license, so all rights stay with lucia3e8. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Adc without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug NXP firmware against it before you order a PCB.
