I already have the full bill of materials for a small ESP32-C5 project and will be routing the PCB myself; what I’m missing is a clean, professionally organised schematic showing every connection exactly as it should be. This must be done on EasyEDA. Key points you’ll need to capture • Core: ESP32-C5 with dual PCB antennas for 2.4 GHz and 5 GHz (antennas to be designed). • Display: Winstar WEO012864D 128×64 OLED on the 30-pin ZIF header, running over I2C. • IR section: TSOP38238 receiver plus TSAL6100 and TSAL6200 LED emitters. • Power: simultaneous support for 5 V through USB-C and a Li-Ion cell managed by a TP4056, with a downstream 3.3 V LDO. • Controls: two momentary buttons tied to power on/off functionality and a separate slide switch. Deliverables - Editable schematic file in EasyEDA format. - PDF export for quick review. - Clear net names and annotation so I can drop the design straight into my board layout stage without hunting for signals. No PCB layout, footprints, or placement work is required—just a logically arranged, error-free schematic that adheres to best-practice wiring and shows any recommended supporting passives for power rails, reset lines, decoupling, USB-C CC pins, and antenna matching where relevant. If something in the parts list needs an extra component to meet datasheet recommendations, flag it in the design rather than leaving it out. Once the schematic checks out, I’ll take it from there.

Hi, I can prepare a clean and well-organised EasyEDA schematic for this project. I have over seven years of experience in ESP32 hardware, power management, displays, sensors, wireless products, and PCB design. I will verify every connection against the component datasheets and include the required decoupling, reset/boot circuitry, USB-C CC resistors, OLED connections, IR receiver filtering, and suitable drivers/current-limiting components for the IR LEDs. All signals will have clear net names so you can move directly into PCB layout. I will also review the power architecture carefully. The TP4056 does not provide complete power-path management by itself, so simultaneous USB and battery operation may require additional circuitry. Similarly, true push-button power on/off will need a proper latch or load-switch circuit. For the RF section, I can include the antenna matching network and design guidance. However, the final PCB antenna geometry depends on the stack-up, board shape, ground clearance, and enclosure, so it must be implemented and tuned during PCB layout. You will receive the editable EasyEDA schematic and a PDF copy. I can complete the work within 4–8days after reviewing the BOM and design requirements. Best regards, Engr. Saddam Gul
