@abdurRafiqM

HI, I am an experienced electronics and PCB Design engineer, specialised in use of ECAD software such as Altium Designer, KICAD, EasyEDA, etc. for the the design of electronics and PCB. I will design your projects to meet your Requirements and the industry standard. I do all kinds of circuits such as Power delivery circuit, Sensor Integrated Circuits, wireless control, MCUs etc. I will deliver the following. The Schematics for your Design The PCB for the design Bill of materials(If needed) Gerber, Pick and Place and other manufacturing and assembly drawings needed. Full Support and consultancy till the project is done. Kindly send me message for my previous designs and also so we can discuss further on your project I look Forward to working with you. Best Regards, Abdur-Rafiq

Hi, I’m a hardware and PCB design engineer with strong experience in RF (Bluetooth), audio systems, and power management for compact, production-ready devices. Your DAP project aligns closely with my background. I can deliver full schematics and a multilayer PCB layout optimized for Bluetooth performance and low-noise audio. I’ll ensure proper partitioning of RF, digital, and analog domains, along with impedance control, clean grounding, and efficient power design to target your 30+ hour battery life. I’ll also handle USB-C integration, dual audio outputs, mic and speaker paths, and MicroSD support—keeping everything compact and suitable for manufacturing. You’ll receive a clean BOM with reliable, sourceable components and well-organized design files for future revisions. Since I also have embedded experience, I can collaborate with you as you review progress to ensure smooth hardware/firmware integration. I can also help validate key choices early (e.g., display feasibility) to reduce risk. Best regards, Dustin

I have experience designing compact embedded audio hardware with BLE connectivity, storage interfaces, and battery-powered systems. I also completed a smart jukebox project based on Raspberry Pi, focusing on audio playback, storage, and power management. For your project, I will design the complete schematic and PCB for the DAP, ensuring clean audio signal paths, proper RF/Bluetooth layout, efficient power management for 30+ hours playback, and a compact manufacturable design. You will receive the schematic, PCB layout, Gerbers, BOM, and hardware design files ready for manufacturing and future updates. I’m also happy to share progress and discuss design decisions during development.

Hi, I have designed compact consumer devices integrating dual-mode Bluetooth, USB-C, battery management for long runtime, and audio circuitry within tight mass-production form factors — directly applicable to your DAP requirements. I will cover all subsystems — BLE SoC for audio and data, high-fidelity DAC and amplifier, dual 3.5mm jack routing, USB-C fast charge and data, microSD, microphone, speaker driver, and power management for 30+ hours playback. One note on the display: high refresh rate video on E-Ink is technically constrained — I will advise the best display option to meet your needs. I will deliver the full schematic, PCB layout, BOM, and all design files for future revisions. Happy to share progress at each milestone given your embedded background. Please feel free to reach out to discuss form factor and component preferences. Kiran

You are looking for a hardware engineer to design a high-fidelity, compact DAP with advanced features, and I can assist with this project. I am an embedded systems and PCB design engineer with 5+ years of experience, and I have already worked on audio electronics, ESP32/Bluetooth-based systems, and power-optimized embedded devices. I can develop a complete hardware solution including schematic design, multilayer PCB layout, and BOM selection with a focus on audio signal integrity and RF performance. I will ensure proper separation of analog and digital domains, low-noise audio routing, and stable Bluetooth connectivity for both streaming and data transfer. USB-C integration, dual 3.5mm outputs, microphone input, speaker driver, and microSD interface will be designed with production-ready standards. For power, I will design an efficient battery management system to meet your 30+ hour target, including charging, protection, and optimization. The design will be compact and suitable for manufacturing, keeping thermal and EMI considerations in mind. I am looking to collaborate closely with you, sharing progress regularly so you can review and guide the embedded aspects. Deliverables will include full schematics, PCB layout files, and a structured BOM ready for production.
