NTC Thermistor 0603 (1608 Metric) Template NO default properties #simplifiedFootprint #noProp #commonpartslibrary #ntc #thermistor #sensor #temperature #transducer

Dual-mode wearable ultrasound collar schematic with A-mode sensing, LIPUS therapy, 3 MHz piezo transducer, power management, control, receive chain, ADC, and safety interlocks.

Compact 2-layer ESP32-S3-MINI-1 piezo TX/RX board for a shared 3 MHz transducer node. Includes USB 5 V input, TP4056 single-cell LiPo charging, TLV75533 3.3 V regulation, ferrite-bead isolated 3V3_ANALOG rail, ~12 V pulsed TX boost rail, low-gate-charge NMOS transmit driver, clamp-protected RX input, 2-stage OPA836 analog receive chain, envelope detector, ADC interface, TMP117 I2C temperature sensor, and status LEDs. Layout intent: piezo centered, RX chain within 10 mm of PIEZO_NODE, boost section remote from RX, digital and analog partitioning, and AGND/DGND star connection near RX front end.

1-Wire®, ±0.2°C accurate digital temperature sensor with authentication, 2-Kbit EEPROM #CommonPartsLibrary #Sensors #Transducers #Temperature
