I will design esp32 stm32 iot circuit, schematic and production pcb

Yes. I can do full ESP32 / STM32 hardware design (circuit, schematic, PCB layout and BOM) or only PCB layout from your existing schematic. Choose the package that fits, or send your files and I’ll recommend the best option.

I work on smart home & building automation, industrial IoT, robotics, agri-tech, environmental monitoring, medical devices, wearables and consumer electronics like wireless mouse PCBs, keypads, trackers and audio gadgets, all based on ESP32 or STM32.

Yes. I regularly design battery-powered ESP32/STM32 PCBs with efficient regulators, charging circuits and protection. I focus on low-power operation so your IoT device can run longer on battery or energy harvesting.

Yes. I can integrate WiFi/BLE using ESP32, and add interfaces like RS-485, CAN, I²C, SPI, UART, Ethernet, relays, displays and sensors as needed. I follow layout rules that help RF performance and signal integrity.

My main tool is Altium Designer, but I also work with KiCad and EasyEDA. I’ll deliver the full project/source files plus Gerbers and fabrication outputs so your manufacturer can produce the PCB.

Yes. You receive schematic PDFs, PCB layout files, Gerber and drill files, pick-and-place/centroid files, BOM and any required assembly drawings. This is everything a PCB/assembly house needs to build your board.

As a rule: • Basic – you already have schematic, I do PCB layout. • Standard – typical IoT node: ESP32/STM32 circuit + schematic + PCB + BOM. • Premium – more complex or industrial IoT device with extra interfaces, layers or stricter requirements.

I follow EMI/EMC-aware layout practices, proper grounding, filtering and decoupling, and consider creepage/clearance and protection devices where needed. This helps your ESP32/STM32 IoT PCB behave better in real environments and during certification tests.

Yes. Many clients start with just an idea or rough sketch. Tell me what your IoT device should do and in which industry (smart home, medical, industrial, etc.), and I’ll help convert it into a clear ESP32/STM32 hardware concept and recommend the right package.
