I created a concept “look” for the ESP32 external audio recorder with battery, USB‑C, microSD, audio input, record button, status LED, and a simple internal block diagram. You can view/download it here:
Yes — since this ESP32 project is view-only, use this link to create your own editable project with the battery, audio recorder PCB placement, and 3D-ready layout brief: Create ESP32 Audio Recorder Project.
In that new project, the layout should be sized before placement and then components can be grouped by function — power/battery, ESP32, audio input, storage, and user controls — with connectors at board edges and antenna clearance preserved.
I’ll review the uploaded project PDF, extract the relevant requirements for the ESP32 recorder/access-control design, then summarize how it should map into the schematic, battery placement, and 3D PCB layout.
I reviewed the PDF: it describes Eco-Connect, an ESP32 recycling kiosk, not the audio recorder/access-control design. I created a hardware + 3D placement brief for the kiosk here: eco-connect-3d-layout-brief.md.
I couldn’t save it into the current project files because this project is view-only for you, so I generated it as a downloadable file instead.
