# xyfP 9Qur rogF ## Description To optimize your 4-layer board manufacturing process with Seeed Studio Fusion, utilize this comprehensive template. It incorporates a majority of the essential manufacturing constraints as global rules, ensuring a smoother and more efficient production workflow. #project-template #template #manufacturer-design-rules This project is a vessel monitoring system built using Seeed Studio Xiao Sense, Xiao Expansion Board with OLED, a UART WiFi module, a normally open float switch, and a UART SIM800L cellular module. The system displays a 30-second countdown on the OLED screen, calibrates the IMU sensor, converts to Euler angles, and stores these values for comparison with future readings. It also sets up the WiFi module as an access point to configure the vessel's name, contact numbers, and angle thresholds for list and trim notifications. Reports are sent at specified times via the cellular module. ## Project Details - **Owner:** kaushikjk - **Created:** 4/2/2025 - **Last Updated:** 4/2/2025 - **Visibility:** Public - **Inner Layers Copper Thickness:** 1oz - **Board Thickness:** 1.6mm - **Copies:** 1 ## Key Components ### U2 — [Seeed Studio XIAO nRF52840 Sense](https://www.flux.ai/seeedstudio/seeed-studio-xiao-nrf52840-sense~k5.md) - Manufacturer Part Number: 102010469 - Manufacturer Name: seeed studio - Datasheet URL: https://files.seeedstudio.com/wiki/XIAO-BLE/nRF52840_PS_v1.5.pdf - Part Type: Microcontroller - Purchase Url: https://www.seeedstudio.com/Seeed-XIAO-BLE-Sense-nRF52840-p-5253.html **Pins:** - 3V3 [pin 12] - 5V [pin 14] - D10_MOSI_P1.15 [pin 11] - D7_RX_P1.12 [pin 8] - D8_SCK_P1.13 [pin 9] - D9_MISO_P1.14 [pin 10] - GND [pin 13] - P0.02_A0_D0 [pin 1] - P0.03_A1_D1 [pin 2] - P0.04_SDA_A4_D4 [pin 5] - P0.05_SCL_A5_D5 [pin 6] - P0.28_A2_D2 [pin 3] - P0.29_A3_D3 [pin 4] - P1.11_TX_D6 [pin 7] *The full schematic, PCB layout, bill of materials, and interactive design are available at [https://www.flux.ai/kaushikjk/xyfp-9qur-rogf~m1](https://www.flux.ai/kaushikjk/xyfp-9qur-rogf~m1).* --- *Generated from [https://www.flux.ai/kaushikjk/xyfp-9qur-rogf~m1](https://www.flux.ai/kaushikjk/xyfp-9qur-rogf~m1)*
