Welcome to your new project. Imagine what you can build here.

This Gerber file contains the necessary information for fabricating the PCB design of a Bluetooth-enabled headphone. The design includes multiple layers, showcasing the electrical connections and component placements on both the top and bottom layers. Top Layer (Copper traces and components): The top copper layer is primarily responsible for routing the signals from key components such as the ESP32 module, MAX98357A audio amplifier, and the microphone. The ESP32 module, responsible for Bluetooth communication, is positioned centrally to optimize signal flow and minimize interference. Decoupling capacitors (100nF) are placed near critical components to ensure signal stability and noise suppression. Audio signal paths, as well as power distribution, are carefully routed to prevent cross-talk and ensure high-quality sound. Bottom Layer (Copper traces): The bottom layer contains the ground plane and additional routing for power and signal connections. The charging module (TP4056) and voltage regulator (AMS1117) are placed to manage power distribution, ensuring stable battery charging and regulated output for the ESP32 and other components. Connections to external interfaces such as the MicroSD breakout and auxiliary input are routed efficiently to avoid conflicts. Additional Components: All critical components are labeled, including decoupling capacitors (100nF) and resistors where needed, as well as external interfaces like the MicroSD card breakout. Mounting holes are provided for secure installation in a headphone casing, ensuring the board can be integrated seamlessly into the final product. The PCB is designed to minimize noise, with short signal paths and proper grounding for high-fidelity audio performance. This Gerber file ensures accurate manufacturing by containing data for copper layers, silkscreen, solder mask, and drill files.

ESP32-S3 touch display development board standardized on a portrait ILI9341 TFT by default, preserving USB-C power, CP2102N USB-UART, I2C touch, PCM5102A audio, microSD, and expansion while assigning KEY1-KEY5 to BOOT, RESET, USER1, USER2, and USER3. The next design pass is driven by a portrait-oriented board resize and user-facing edge placement of the display area, touch interface, controls, and primary connector access.

> ESP32-based multi-channel audio and haptic control system powered by an external 12 V input, engineered to drive 8 vibrotactile outputs and 2 speaker channels. The design includes integrated thermal monitoring and offers optional support for AUX and microSD audio sources, ensuring flexible multimedia and feedback applications in a compact, efficient platform.

Bilateral smart running insole data logger using two nearly identical ESP32-S3 pressure-sensing PCBs. Left variant is an ESP-NOW slave without microSD; right variant is the master with microSD logging. Both preserve the 16-zone FSR mux front end, LiPo charging, AP2112K regulation, USB-C charging input, JST battery connector, and the 280mm x 90mm 2-layer low-profile insole form factor.
