+**Screening Task 7 Submission | FOSSEE eSim Semester Long Internship (Autumn 2026)**
+
+- **Author:** Aayushman Das
+- **Department:** Electronics and Telecommunication Engineering (ETCE)
+- **Institution:** Jadavpur University, Kolkata
+- **Target Platform:** eSim v2.5
+
+---
+
+## Project Overview
+A production-grade, 4-layer mixed-signal avionics flight computer and environmental telemetry node designed in eSim v2.5. The board incorporates an ESP32-WROOM-32U microcontroller with U.FL external RF breakout, Quectel L86 GNSS receiver with integrated patch antenna, Bosch BMP390L barometric altimeter, STMicroelectronics LSM6DSOX 6-axis IMU, 128 Mbit SPI NOR Flash, and an AP63203 synchronous buck regulator (7.4V–25.2V input down to 3.3V @ 2A).

+## Video Demonstration
+- **YouTube Walkthrough:** [Watch Task 7 Video Demonstration](https://youtu.be/cIcnoNsfvB8)
+
+## Key Technical Specifications
+- **Stackup:** 4 Layers (F.Cu Top Signal, In1.Cu Solid Ground Plane, In2.Cu Dedicated 3.3V Power Plane, B.Cu Bottom Signal)
+- **DRC Validation:** 0 Errors, 0 Unconnected Nets (24 intentional thermal ground via exclusions for MCU1)
+- **Portability:** All 3D STEP assets are locally referenced using `${KIPRJMOD}` for clean out-of-the-box loading.
