Ultrasonic Ranging & Detection Development Shield for Arduino GIGA R1

Custom Shield Design for Arduino GIGA R1 WiFi and mechanically compatible boards (e.g., AURIX™ TC375 Shieldbuddy). It extends the board with sensors: 4x Infineon MEMS microphones: capable of operating in ultrasonic range at approx. 20-80 kHz (datasheet). 2x Ultrasonic Transducers: transmit ultrasonic waves with a center frequency of ~33kHz (datasheet). 2x Instrumentation Amplifiers: providing 4x channels total, routed to external pin headers for connecting additional sensors such as surface EMG electrodes (datasheet). 1x Infineon Barometric Air Pressure Sensor: provides pressure and…
