I will design a small circuit board using esp32 or stm32

Do you need a custom PCB for an ESP32, STM32, IoT, sensor, automation, or industrial control application?

I will design a professional schematic and PCB layout based on your requirements and prepare the project for prototype manufacturing with JLCPCB, PCBWay, or another manufacturer.

My service can include:

ESP32, STM32, or other microcontroller-based circuits

Power supply, input protection, reset, boot, and programming circuits

Sensors, ADC, DAC, relay, MOSFET, servo, and PWM interfaces

UART, I2C, SPI, RS485, CAN, USB, and Ethernet interfaces

Protected 12V/24V industrial inputs and outputs

Component selection and LCSC-focused BOM preparation

Custom symbols and footprints

Two-layer or four-layer PCB layout

Grounding, decoupling, thermal, EMI/EMC, and DFM considerations

Gerber, drill, BOM, CPL/PNP, schematic PDF, and 3D files

I work with KiCad, Altium Designer, and EasyEDA and have over 6 years of experience in embedded hardware, IoT devices, industrial electronics, and PCB manufacturing support.

This Gig is intended for small and clearly defined circuit boards. Complex high-speed, RF, high-power, firmware, enclosure, prototype assembly, and certification work require a custom quota
