I need a fully-ready EasyEDA project for a compact ESP32-WROOM-32E based board that will perform vehicle tracking and telemetry. The board must accept vehicle power, expose a CAN bus via the SN65HVD230 transceiver, capture motion with an ADXL345, obtain location through an external GPS antenna, and upload all data over the mobile network using the SIM7000G LTE-Cat-M/NB-IoT module. All circuitry, footprints, and routing have to be prepared so I can send the files straight to JLCPCB for assembly. That means the EasyEDA workspace should already include a clean schematic, a routed PCB, a JLC-compatible BOM, and the corresponding CPL/placement file. Please keep the component library limited to parts that JLCPCB can source from its basic or extended catalogue; if a footprint is custom, include it inside the project. Physical requirements • Single automotive power input (9–32 V tolerance) with reverse-polarity and transient protection. • U.FL pads for both GPS and LTE antennas. • A keyed pin header for vehicle harness connections: power, CAN-H/L, and a spare UART. • Board size and exact shape are flexible but should remain small enough to fit in a generic plastic enclosure. Deliverables 1. EasyEDA project archive (schematic + PCB). 2. JLC-formatted BOM and CPL files. 3. Standard Gerbers generated from EasyEDA. I will review by importing the project into EasyEDA, running JLC’s assembly preview, and checking that the CAN, GPS, motion, and cellular sections correspond to the functional blocks above.
