Create a professional, detailed electrical schematic for a low-cost industrial sensor controller based on the **TI MSPM0G3505SPMR**, 64-pin LQFP. The schematic must be electrically structured and readable, not a decorative illustration. Use standard IEC/ANSI schematic symbols, clear net labels, component reference designators, exact component values, and clearly separated functional blocks. IMPORTANT DESIGN REQUIREMENTS: * Optimize for LOW COST. * All passive SMD components must be **0603 minimum**. Never use 0402 or smaller. * Use SOIC-8, TSSOP, SOT-23, SOT-223 and LQFP packages where possible for easy manual soldering. * Show every passive component around the ICs. * Show exact component values. * Clearly show power rails and where each decoupling capacitor connects. * Clearly distinguish MAIN GROUND from ISOLATED SENSOR GROUND. * Do not electrically connect the isolated sensor ground to the main ground. * Use a clear galvanic isolation barrier. ============================================================ 1. MAIN POWER INPUT ============================================================ Input: J1 = 24 V industrial power input. 24V_IN → F1 → +24V_PROTECTED. F1: * 0.75 A fuse. Add an optional TVS diode footprint: D1 = TVS diode, DNP initially. Clearly mark it "DNP / OPTIONAL". Input capacitors: C1 = 10 µF / 50 V, 1206, X7R C2 = 100 nF / 50 V, 0603 Both connected from +24V_PROTECTED to GND_MAIN. ============================================================ 2. MAIN 24 V → 3.3 V POWER SUPPLY ================================= Use: U2 = **ST L6981N33DR** * Fixed 3.3 V output * Low Noise Mode * SOIC-8 The schematic must show the complete buck converter, including: * VIN connection * SW node * inductor * output capacitors * ground * feedback/fixed-output configuration * all required datasheet support components. Use: L1 = 22 µH shielded power inductor, approximately ≥2 A saturation/current rating. Suggested example: TDK B82464G

Design a complete PCB for an interactive emotional robot. The robot should: - Hear speech through a microphone and recognize positive or negative words. - Become happy when spoken to kindly and sad when insulted. - Display emotions through two animated eyes. - Look left, right, up and down. - Blink automatically. - Move its eyebrows, eyelids, mouth and head using servomotors. - Play sounds or speech through a speaker. Include the microcontroller, microphone, audio circuit, eye displays, servo drivers, 5V/3.3V power supplies, battery protection, connectors, and all necessary components. Provide the complete schematic, component values, pin connections, PCB layout, and basic firmware architecture.

A non-inverting op-amp amplifier with a gain of 10 using a 1 kΩ and 9 kΩ resistor

The Arduino Uno, powered through a USB connection, acts as the central controller of the Battery Management System (BMS). Its 5V and GND pins supply power to all the modules through the breadboard power rails. The battery voltage is monitored using a voltage divider made of two 10 kΩ resistors connected to analog pin A1, while the ACS712 current sensor is powered by the Arduino and connected to analog pin A0, with the load connected in series through its IP+ and IP− terminals to measure current. The DHT11 temperature sensor is connected to digital pin D2 to monitor battery temperature. An I2C OLED display is connected to pins A4 (SDA) and A5 (SCL) to display real-time voltage, current, temperature, and system status. A relay module connected to digital pin D7 disconnects the load during fault conditions, while a green LED (D9) indicates normal operation, a red LED (D8) indicates faults, and a buzzer (D10) provides an audible alarm whenever over-current, under-voltage, or over-temperature conditions are detected.

Create a diagram for a Scoppy oscilloscope using an ADS1115 and a Raspberry Pi Pico to mesure 3v3, 3.7v and 5v from one single set of test hook probes. It needs reverse polarity protection and a voltage divider for the 5V input; it also needs 3 buttons to be able to switch between the 3 different voltages when testing.

Create a clean, minimal, and professional electronic block diagram and netlist for a microcontroller-based measurement tool. System Components: 1.
