Hi In this project we want to make a Small approximately (3cm by 5cm) PCB All components must be also very small No over heat is allowed Its main features are: 1. Using USB Type C, Charging 2 Lithium ion batteries (2000 mAh & 3.7 V) connected to it at the same time 2. a good MCU must be used 3. BLE so that apps on smartphones can communicate with it 4. Have a basic push button right at the centre 5. LED Indicator for level selected and charging or low battery indication. 6. One input pin for an Analog sensor 7. One output pin for the power of the two batteries delivered in series 8. FCC / CC / and other certifications must be guaranteed to pass 9. The One Output pin's power must be controlled in an ON/OFF fashion using a mosfet controlled by the MCU 10. Smart, Safe, and Efficient management of the power so that it can be turned on and off using the single push button and automatically cut power if output pin short circuited or something. 11. I must clarify that the USB-C charges the batteries and also provides the circuits power but when the USB-C is disconnected, the board must use the charged batteries and so the MCU should be powered by the batteries as well and control the output voltage too which comes from the same two batteries mentioned in series. *** Thanks for reading so far, the mentioned features are crucial and if you do not have professional experience with them, I am sorry to say that we would not be able to do this project together *** [ Please read and answer the following questions carefully as they will be my main deciding factor ] Feel free to ask me any questions or clarifications. So now that I have explained the general requirements please answer the following questions: 1. Please share some pictures/links/info about some of the similar projects that you have done. 2. We have professional engineers as consultants, so we have a good idea what is best practice. What kind of MOSFET, MCU, BLE would you use ? 3. Are you experienced with Safety Certifications in North America ? 4. Please note that if a milestone is not 100% complete, then no payment can be released and full refund is expected. 5. I am flexible regarding a realistic deadline that we come to agreement about but if that deadline is missed or you fail to respond to my messages within 2 days, I will have no choice but to cancel the project and 0 payments will be made. 6. Obviously all source files, design files, codes, libraries must be handed to me with each iteration, I need to deeply analyse and test each step. 7. What software do you use ? altium ? eagle ? ... 8. The projects idea and related files + data + info must be kept confidential between me and the person who does the project. 9. Once we finish the project, I will be the sole owner of this intellectual property. 10. You need to take responsibility as an engineer and guarantee the certifications pass and make any changes required if they fail, else the project is pointless. 11. We are based in Canada (Toronto) so if you happen to be close it us, its a plus. Thank you for your time, Adrien

Hello. I use Altium. Already have theoretical knowlage with Safety Certifications in North America. To know details about my projects you could go to my freelancer profile. MCU and BLE will be nordic semiconductor 51 or 52 series. MOSFETs will be any just to feet in size of PCB and designed for enough drain-source current. I prefer to use Altium instead of Eagle but its still up too you.
