We have developed an earthquake early-warning network in Mexico and other countries, providing up to 2 minutes advance warning. We need to improve the PCB for our sensor to make it cheaper to produce, so we have chosen to use Seeedstudio parts and guidelines. SCHEMATIC DESIGN We already have a PCB schematic for our sensor (attached in Eagle) which includes the ESP32, the ADXL355 accelerometer, a piezo buzzer, and Neopixel LED (ws2812b). We want you to take our existing schematic design and add some components: 1. Transistor from 5v input for power to buzzer ,making it louder 2. 10uF decouple capacitor for Neopixel (ws2812b) 3. Ethernet controller and terminal. Please use this design ([login to view URL]) as a guide. Use the included schematic design, but find similar components from the Open Parts Library (see below). We want you to make sure all the components are available in the Seeedstudio Open Parts Library ([login to view URL]), so that we can order board can at a lower cost. Make sure to look in both the Shenzhen and Seeed catalogs in the search bar. We understand that the ADXL accelerometer is not available in the Open Parts Library and we will supply that separately when we order the boards. Once the schematic is done, please provide a PDF and .SCH eagle file for us to review, as well as a BOM using the Seeedstudio xls format (attached). Remember to check all parts specified can be found in the Open Parts Library. PCB BOARD DESIGN Please create the PCB board following these guidelines: 1. Decoupling capacitors should be next to their corresponding chips 2. Board outline should use attached DXF file. 3. The components should be arranged like this ([login to view URL]) - ESP32 Wroom antenna should overhand the top edge, accelerometer should be in top corner, buzzer in bottom left. The power and ethernet jack should both be along the bottom edge of the PCB. 4. The design should follow Seeedstudio's guidelines: [login to view URL] Once the design is ready, please submit the eagle BRD file. We will create the gerbers ourselves and add the silkscreen graphics. Thanks!
