This element is part of a kit, which is composed of :
A single-design board going up to 64Msps, with a 2000 lines capacity, will be made available soon. Don't hesitate to drop me a message if you are curious.
__ Headers are not included!__
The aim of this module is to get the electrical signal coming back from a transducer, and to deliver the signal, analogically processed, with all the intermediary signals accessible to the user.
- Getting access to a TGC
- Getting the envelope of the signal
- Cleaning the signal before feeding in the on-board SPI ADC
All key signals are accessible, and jumpers, as well as pots, enable on-board fine-tuning of the signals.
This gave for example the following image from a vintage ultrasound probe found on ebay:
This module is part of a project has a specific target of providing a low-cost, open source technological kit to allow scientists, academics, hackers, makers or OSHW fans to hack their way to ultrasound imaging - below 500$ - at home, with no specific equipment required. For complementary sources of information, you can visit the Hackaday Page, our github repo or the online modules manual.
The results are detailed below:
It's also extremely robust, extremely versatile, and having access to all intermediary signals enables you to do whatever you want with your ultrasound imaging system.
Sure! You can find the Kicad and Altium files here](https://github.com/kelu124/echomods/tree/master/goblin). Make it yourself! Part of the price here includes the fab fees and my own costs.
Schematics are here.Here's a small graph for the link between ICs:
- Now that the pHAT design is stabilized, it's being produced by MacroFab - which does the fulfillment.
- Attention: The board comes without headers/jumpers .. up to you to put yours!
