About the AD7124-4-Implementation PCB

AD7124-4-Implementation is an open source NXP PCB design by fedecastellaro, published on GitHub. It is a 2-layer board measuring 114.2 × 98.8 mm, with 36 components from 26 distinct parts.

Its main chip is the LPCXPRESSO1769, from the NXP family. Other key parts include the LM2575-5.0, MP3V5050GP, MCP6002-xSN, AD7124 and NCP1117ST33T3G. By type, the board carries 14 capacitors, 8 resistors, 7 ICs, 3 connectors, 1 switch and 1 diode.

From the project

AD7124-4 - 24-Bit ADC, 4-Channel , Sigma-Delta - PCB and software implementation

This are the files of a very simple but effective Sphygmomanometer. It uses a MP3V5050GP as a pressure sensor, a 2nd order Butterworth low pass filter, a LPC1769 dev-board as uC, and a LCD 16x2 to present values.

AD7124-4-Implementation: common questions

What microcontroller does the AD7124-4-Implementation use?

The AD7124-4-Implementation is built around the LPCXPRESSO1769, from the NXP family.

How big is the AD7124-4-Implementation PCB?

The AD7124-4-Implementation measures 114.2 × 98.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the AD7124-4-Implementation?

36 components, from 26 distinct parts. The full bill of materials is listed on this page.

Where can I download the AD7124-4-Implementation design files?

From the fedecastellaro/AD7124-4-Implementation repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the AD7124-4-Implementation design in my own project?

The repository has no license, so all rights stay with fedecastellaro. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the AD7124-4-Implementation 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.
