About this project

Open

Hello, we are Vagai Vanigam, a start up for electronic products. We are developing a project which involves reception of ultrasonic signal from two transducer through PA5 and PA7 ADC pins of Stm32f103c6. Signals from transducer is amplified using inverting mode of TL072 and fed to ADC. Design is in KiCad using 2 layer design. Things we need:
1. Previous Analog and digital circuit to be checked and optimised
2. A digital switch between SPWM from microcontroller and aux input to be added
3. Voltage regulator from 15v to ams1117 3.3v that is found in design with reverse voltage protection
4. Optional low pass filter or peak detector circuit to be included for both ultrasonic receiver
5. Finalise PCB layout including for avoiding cross talk, containing impedance control, ground plane, ground return path

Project overview

Tx is 40khz transmission through ultrasonic transducer. J3&5 are from ultrasonic receiver fed to ADC of STM32f103. SPWM from pins PA8&9 are fed to low pass filter and amplified with LM386 to suit headphone.
