About the BRIDGEADC01 PCB

BRIDGEADC01 is an open source PCB design by mlab-modules, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 40.1 × 40.1 mm, with 40 components from 32 distinct parts.

Other key parts include the MIC4426 and AD7730. By type, the board carries 23 connectors, 7 capacitors, 3 resistors, 2 ICs, 2 diodes and 2 inductors.

It belongs with the sensors designs in this gallery.

From the project

Strain Gauges analog front end and 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.
