Circuit & Schematic Design

$25/hr Starting at $1K

I help clients develop a technically sound, well-structured circuit and professional schematic that is ready for PCB design, review, prototyping, and manufacturing.

This service is ideal for Startups, hardware teams, inventors, manufacturers. It is structured for commercially serious projects where reliability, performance, documentation, communication, and production readiness matter more than simply completing a drawing.

SERVICE SCOPE

✅ Analog, digital, power, sensing, control, communication, RF-support, and mixed-signal circuit design
✅ MCU and processor interfacing for STM32, ESP32, nRF52/nRF53, NXP, TI, i.MX, Raspberry Pi, and related platforms
✅ Power-tree design, regulation, battery charging, protection, filtering, level shifting, clocks, reset, debug, and programming
✅ USB, UART, I2C, SPI, CAN, RS-485, Ethernet, audio, display, storage, sensor, and actuator interfaces
✅ Component selection with availability, lifecycle, cost, package, tolerance, derating, and manufacturability awareness
✅ Structured design review and electrical-rule checking before PCB layout

WHAT YOU WILL RECEIVE

✅ Editable schematic source and PDF
✅ Preliminary or complete BOM with manufacturer part numbers
✅ Design notes, interface definitions, and PCB-layout constraints

ENGINEERING APPROACH

I normally begin by reviewing the product objective, development stage, available files, interfaces, expected quantities, enclosure constraints, operating environment, compliance targets, and the client’s main technical concern. For complex work, architecture review and finalization are completed before detailed circuit or PCB design begins.

I focus on design margins, protection, startup states, unused pins, power sequencing, grounding strategy, programming access, test points, and failure conditions—not only connecting datasheet reference circuits.

RELEVANT EXPERIENCE

Suitable for new product development, redesign, prototype correction, custom controller boards, sensor products, wireless devices, and industrial electronics.

Projects may be completed hourly or through clearly defined milestones. Components, fabrication, assembly, shipping, laboratory certification, paid software/services, and other third-party costs are separate unless specifically included.

To receive an accurate scope, please share the product requirements, existing schematic or PCB files, block diagram, datasheets, mechanical information, expected deliverables, target schedule, and any known technical issues.

Keywords: circuit design, schematic design, electronics circuit development, analog circuit, digital circuit, mixed signal design."
