TDK 3-terminal feed through filter_YFF-AC series is a product which has feed through structure that the direct current goes through inside the component. This structure makes the distance from the product to GND shorter and reduces the ESL. Parallel effect by GND electrodes at both sides provides low ESL.

ATMEGA328-PU (U1) Setup Power Supply Connections: Connect U1:VCC to U2:5V@1 (5V power supply). Connect U1:GND to U2:GND@1 (Ground). Connect U1:AVCC to U2:5V@2 (Analog Power Supply for better ADC performance). Multiple GND pins (U2:GND@1, U2:GND@2, U2:GND@3, U2:GND@4) should all be connected to a common ground plane for stability. Serial Communication for Debugging: Connect U1:PD0 (RX) to U6:TXD. Connect U1:PD1 (TX) to U6:RXD. These connections enable serial communication between the microcontroller (ATmega328) and the USB-Serial adapter (CH340N) for programming and debugging. Sensor Data Acquisition: Given the components, the MLX90614ESF-ACC-000-SP (U4) is an infrared temperature sensor that could be used for vital detection. It uses an I 2 2 C interface. Connect U1:PC4 (SDA) to U4:PWM_SDA. Connect U1:PC5 (SCL) to U4:SCL_Vz. This allows the ATmega328 to communicate with the MLX90614ESF infrared temperature sensor. Additional Considerations: An analog-to-digital converter (ADC) or a specialized RF module designed for UWB radar applications would be necessary to capture and process radar signals for detecting human vitals through walls. The MAX270CWP+ (U3) could be used for audio signal processing but may not directly apply to UWB radar signal processing. Power Supply to Other Components Connect U6:VCC to U2:5V@1. Connect U4:VDD to U2:5V@2. Ensure all components' ground pins are connected to the common ground plane (U2:GND@1, GND@2, GND@3, GND@4)
