README.mdBRIDGEADC01A
High sensitivity Bridge Transducer ADC
The module is a complete analog front end for weigh-scale and pressure measurement applications. The device accepts low-level signals directly from a bridge transducer and outputs a serialdigital word on SPI interface.Exitation voltage could be generated by module itself. Exitation signal is synchronous with internal signal sampling.

Questions
How big is the BRIDGEADC01 PCB?
It measures 40.1 × 40.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the BRIDGEADC01 use?
44 parts, built around the MIC4426YM and AD7730BNZ. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the BRIDGEADC01 KiCad files?
From the mlab-modules/BRIDGEADC01 repository on GitHub, at the commit this page was made from: the board is hw/sch_pcb/BRIDGEADC01.kicad_pcb and its schematic hw/sch_pcb/BRIDGEADC01.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the BRIDGEADC01 design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
