We're looking for an talented electronics designer with problem-solving capabilities and experience in power design to re-work an energy harvesting IoT device. We have a (simple) Energy Harvesting device using a LT module to harvest power from either Solar/TEG + rechargeable li backup battery. This drives a low power Microcontroller which manages the data + duty cycle of a CATM1 modem for connectivity. Prototype pictures attached Currently the power system is not working/stable. We need to investigate the issue + re-evaluate the component level design so we can meet specs. Experience: - Experience with power design + PCB design is a must. - Energy harvesting design is a plus - Hands-on debugging/bring-up is a nice to have. The expected tasks would be - Analyse existing design / issues - (Optional) Hands-on debugging - Recommend components - Respin schematics/layout - (Optional) Hands-on bring up/testing There are some other smaller tasks (like optimising the antenna design/placement, filter circuits, firmware programming) but the power is obviously the biggie. What we're looking for. - Professionalism and good communication is essential - Problem solving attitude/capabilities We're based in GMT+8 so ability to communicate at sane times would help! First Steps Please leave a short message / cover letter as introduction. We will suggest a short fixed-price task for any shortlisted candidates to ensure we can work well together then proceed with the main task.

Hello, Thanks for your job posting. I have read your project details carefully, and I’m ready to handle it and deliver on time with high quality. I’m an Embedded systems engineer with +3 years of experience in designing and developing software and hardware for different projects over plenty of microcontrollers like PIC, AVR, STM32, and TIVAC. I’m also an Arduino specialist, professional PCB designer with (Eagle CAD, Altium, EasyEDA), and an expert in coding with C, C++, and Python. That’s a sample of my projects: - Self-driving car prototype - Handy powerpack manager - Obstacle avoidance robot - Fighter robot - Line follower robot I will offer you this project: - Efficient software and hardware design. - Complete flow chart for software or system behavior. - Well commented software and documentation by using the Doxygen tool. - Provide hardware circuit schematic and PCB layout. So I'm looking forward to hearing from you soon to discuss more details. Thanks, Ahmed Ashraf

Hi. I am a CID certified PCB design engineer. I work to IPC standards to ensure the highest quality of work. I have a lot of experience in small embedded systems like the one you are developing. The BG96 is the bigger brother to the BG77, which i am working on with another client. So i am familiar with the power constraints in the Quectel devices. Debugging is part of my day, so it shouldn't take long to get to the cause of the problem. I am UK, English speaking.
