I would like to hire a Circuit Designer This project requires the schematics, PCB layout and BOM for 2 circuit boards I need to repair and modify though I don't know how they work exactly. On the attachments you can find the best pictures I could get of the 2 boards, with some components listed. I have also included the datasheets of the IC I think are there, but this needs checking, I don't have the skills to know. As the project gets assigned, I can try to help tracing the circuits by checking different connections, but I can't do much more than that. The project will be assigned for the designer who can provide the most troublefree solution (which gives me the least work) along with the best price. 27 Engineering, Circuit Design Apr 25, 2017 Apr 25, 20174d 22h $441

FPGA microphone PDM-to-USB digital audio interface You should be very competent in FPGA and DSP, especially for audio signal processing. You should also have worked on MEMS microphone with PDM digital interface. What I need you to do is the following: 1. select a Xilinx FPGA such as Spartan 6 for 2. hooking up 16 MEMS digital microphones with PDM interface 3. simultaneously sampling audio at 16-bit 48KHz 4. send out through USB as USB Audio Your deliverables include: - Electronics (BOM, schematics, PCB layout, etc) - firmware (project, source code, etc) - test package (electronic test points, firmware testing, and computer verification process) Please indicate if you can source all parts (FPGA, MEMS microphone etc) and fabricate PCB on your side within one week. I want to avoid lengthy international mailing. So this is essentially a 16-microphone PDM-to-USB interface. We will test and accept the above with running Audacity on computer to collect and playback audio data collected from your work. Additionally, we need you do audio DSP processing (such as FFT) on this FPGA. We will provide details on those later. Please bid for the pure interface part first. Please highlight your previous relevant projects and your experiences. 16 Electronics, Verilog / VHDL, PCB Layout, Circuit Design, FPGA Apr 22, 2017 Apr 22, 20171d 6h $1199
