FAQ
What wearable IoT devices can you develop?
I can develop fitness trackers, health monitoring prototypes, smart wearables, activity trackers, asset trackers, industrial wearables, connected sensors, and custom IoT prototypes.
Which microcontrollers do you work with?
I primarily work with ESP32, ESP32-S3, ESP32-C3, nRF52, nRF52832, and nRF52840 platforms.
Can you design the PCB as well as the firmware?
Yes. I can handle schematic design, PCB layout, component selection, BOM, manufacturing files, embedded firmware, and hardware integration.
Can you integrate an IMU?
Yes. I can integrate accelerometers, gyroscopes, and 6-axis or 9-axis IMU sensors for motion, orientation, activity, and gesture tracking.
Can you add Bluetooth or LoRa connectivity?
Yes. I can implement BLE, LoRa, LoRaWAN, and Wi-Fi connectivity depending on your device requirements.
Can you develop low-power wearable devices?
Yes. I can optimize firmware, configure sleep modes, manage peripherals, and design battery-powered systems with power consumption in mind.
Can you integrate other sensors?
Yes. I can integrate temperature, humidity, pressure, heart-rate, GPS/GNSS, RFID/NFC, motion, proximity, and other compatible sensors.
Will I receive the source code?
Yes. Source code is included according to the selected package, along with relevant technical documentation.
Can you work with my existing PCB or hardware?
Yes. I can review existing schematics, PCB layouts, components, and firmware and help with debugging, modifications, or further development.
Can you develop a complete prototype from my idea?
Yes. Send your requirements, sketches, block diagram, or existing hardware details, and I can help develop the system architecture, electronics, PCB, and firmware.
