Compact ESP32 Voice Assistant PCB
Budget: ₹100 – ₹400 INR
I’m building a small-footprint “Macho” voice-assistant board and need a complete hardware package created in EasyEDA. The core is an ESP32-WROOM-32 (38-pin dev board) paired with a 0.96" I²C OLED, an INMP441 I²S microphone, and two TTP223 touch sensors. I’d also like a row of additional GPIO headers for future expansion.
Scope of work
• Draw the full schematic, matching the real-world pinouts of every off-the-shelf module so that each one can drop onto male headers on the PCB without re-soldering.
• Produce a compact PCB layout that keeps the overall footprint as small as practical while maintaining sensible routing for I²C and I²S lines.
• Deliver manufacturing files: Gerbers, BOM, and Pick-and-Place data.
• Optionally, quote turnkey PCBA so I can order the first batch fully assembled.
All files must be native EasyEDA projects so I can tweak or revise them later. If photos, datasheets, or mechanical drawings would help, just let me know and I’ll supply them right away.
Looking forward to your questions and your timeline to get this board ready for production.
