About the ENGR357 SDR PCB

ENGR357 SDR is an open source PCB design by jaronbrown, published on GitHub. It is a 4-layer board measuring 100 × 100 mm, with 128 components from 39 distinct parts.

Other key parts include the PCM1808PWR, TPS7A8001DRBR, SI5351A-B-GT, SN74CBT3253 and ADA4805-2ARMZ. By type, the board carries 41 capacitors, 33 test points, 26 resistors, 9 ICs, 9 inductors and 3 jumpers.

It belongs with the rf & radio and audio designs in this gallery.

From the project

The microPython module to control the SI5351, si5351.py, was provided by https://github.com/thaaraak/Tinypico-Radio/tree/master. Some minor changes were made to the setter in order to allow individual clock enabling/disabling--used for the AM mixer local oscillator.

The radio control is handled by radio.py which after initializing a , can be used to parse Quisk commands and automatically control bandpass filter selection (based on frequency) and frequency. The bandpass filters can also be controlled manually by entering "BAND,AUTO" to allow for manual testing and use of the built in bypass…
