Ultrasound is an open source PCB design by rosalyntg, published on GitHub under the GPL-3.0 license. It is a 4-layer board measuring 165 × 113 mm, with 343 components from 46 distinct parts.
Other key parts include the AS78L05RTR-E1, MCP1755ST-1802E/DB, HV7321K6-G, AD8332ARUZ and ADC34J22IRGZ25. By type, the board carries 221 capacitors, 84 resistors, 16 ICs, 9 diodes, 6 connectors and 4 transistors.
From the project
Hobby Ultrasound Machine
This repository contains the PCB design files, FPGA firmware files, and host software for a hobby 8 channel ultrasound system. It can do phased array operation. Here's an example of the pulse in my forearm:
Picture of the functioning ultrasound system:
The parts of the ultrasound consist of: - The probe, which is a Acuvision 4V1c probe bought off ebay - As far as I can tell, it has 112 elements. I think a bunch of them are broken for this unit, so I've atttempted to work around as best as possible - The power board - This provides a variable voltage positive and negative rails for the…
