Hi there, I’m excited to partner on your wearable emergency communication device. With a strong background in Electrical Engineering, Embedded Systems, and wearable-grade hardware design, I’ve delivered compact, power-efficient boards, robust firmware, and turnkey prototypes for GPS/GSM IoT and low-power cellular modules. I will provide a complete design package: a KiCad/Altium circuit board schematic and BOM, production-ready firmware in C/C++ or MicroPython, a 3D-printable enclosure, and a short demo video that showcases the four core features: emergency signaling, precise positioning, SMS alerts, and the audible alert. What sets me apart for this project: - End-to-end hardware-software integration: from PCB routing to firmware, RF considerations, and power management to extend battery life. - Expertise in GPS modules, low-power wake/sleep strategies, and reliable communication stacks suitable for constrained IoT devices. - Practical, testable hardware design with documented bill of materials and revisions, plus a ready-to-build 3D enclosure. - A clear project plan with milestones, risk mitigation, and a realistic timeline for a working MVP. Proposed approach: 1) Define system architecture: microcontroller selection, GPS/GSM or alternative IoT module, power budget, and anti-noise design. 2) Schematic capture and PCB layout in KiCad/Altium, with a concise BOM and enclosure-fit considerations. 3) Firmware development: wake-on-event, GPS readouts, emergency button logic, SM

@yaroslavmark

✅Okay, I got what you want exactly. I am a senior embedded systems engineer with over 10 years of experience, providing low-power IoT hardware design, PCB development, firmware in C/C++, and GPS/GSM integration for wearable devices. In my opinion, the key to making this device reliable is choosing an ultra-low-power MCU paired with an LTE-M/NB-IoT module and optimizing sleep cycles so the battery can last weeks, not days. I would also design the PCB with a compact 4-layer layout to improve RF stability and GPS sensitivity while keeping the form factor small enough for a wearable accessory. This project is very similar to my previous works. I recently developed a wearable safety tracker using an STM32L4 MCU with a Quectel BG95 module and u-blox GPS, where I optimized power consumption down to 120µA in standby and implemented encrypted SMS + MQTT alerts. I also designed the PCB in KiCad (38 components, 4-layer board), built the firmware in C++, and delivered a 3D-printed enclosure with a magnetic clip system for field testing. Via private chatting or meeting, I will provide the creative idea and good tech solution for your project and i want to discuss about the budget and timeline in detail. Best regards. Yaroslav
