I will develop esp32 stm32 iot pcb, ble and embedded firmware

HELLO AND WELCOME BUYER!!

I can develop custom IoT PCB hardware, ESP32/STM32 systems, BLE connectivity, sensor interfaces, power management, and embedded firmware for connected devices, automation systems, monitoring equipment, smart products, and industrial applications.

Service Included:

Custom IoT PCB schematic and PCB layout

ESP32 / ESP32 S3 hardware development

STM32 based embedded PCB development

BLE hardware and firmware integration

WiFi and wireless IoT connectivity

Sensor and actuator integration

Why Choose Me:

I don't treat PCB design and firmware as separate tasks. The hardware architecture is planned around the firmware requirements, including GPIO allocation, communication buses, interrupt handling, power states, debugging access and future expansion.

You receive organized, editable engineering files and practical documentation designed for prototyping, testing and further product development.

Message me with your project details and let's turn the concept into a working embedded system.
