About this Gig

A schematic can look correct and still fail after manufacturing.


I provide practical schematic and PCB reviews for STM32, ESP32 and embedded hardware projects before prototype production.


I can review:


- MCU power, reset, boot and programming circuits

- DC-DC, LDO, charging and protection circuits

- CAN, RS485, RS232, UART, SPI, I2C, USB and Ethernet

- 4G, Bluetooth, 2.4 GHz RF and Wi-Fi modules

- Displays, sensors, microphones and audio amplifiers

- Brushed DC H-bridge and BLDC three-phase bridge circuits

- PCB placement, routing, grounding and power paths


You will receive:


- A prioritized issue list

- Screenshots showing the exact problem locations

- Risk explanations and practical correction suggestions

- One recheck after you update the files


Supported files:


- Altium Designer

- EasyEDA / JLCEDA

- KiCad project files

- Schematic PDF

- PCB screenshots or manufacturing files


Please contact me before ordering if your board has multiple schematic pages, high voltage, custom RF design, DDR, high-speed interfaces or complex power electronics.


Firmware development, physical board testing and full redesign are not included in this Gig.
