BOM will be provided to promising applicants I have a BOM and some circuit design files that need to be converted to an eagle schematic that allows me to make design modifications in the future. I have made this PCB in the past but do not have the schematic files to make modifications. The order of components needs to stay the same and the size of the PCB must stay the same. The PCB is for a pressure sensor array with vibration motor drivers and BLE communication. It also includes a rechargeable battery module. This is a 2 part project, the first part is to recreate the original PCB and the second part is to improve the battery charging module for the PCB. 1) Make Eagle schematic and Gerber files based on circuit design drawing and BOM provided. Keeping the PCB size constrains the same and the positioning of the RGB LED, Power Button and charging port the same. -Size is: 19mm X 96mm. -Thickness is 1.6mm. -Material is FR-4 TG130. -Copper Thickness 1oz. Inner copper thickness 0.5oz. -Surface finish HASL. -Min tracking/spacing = 6 mil -Min hole size = 0.3mm 2) Improve the charging speed of the PCB. Our previous PCB took more than 4 hours to charge a 3.7V LiPo battery. We would like to reduce this time to 2-3 hours if possible. We would also like the freelancer to double check the motor driver which controls the vibration motors in our PCB. The motor drivers should provide a steady 3V supply to each of the 4 motors but this seems to decrease with the battery level. Proposed Milestones: 1) Eagle Schematic and Gerber Files for Original PCB, BOM (20% payment) 2) Eagle Schematic, BOM and Gerber Files for Improved PCB, BOM (20% payment) 3) Testing of both PCBs in our office after we have them manufactured based on the gerber and BOM files (60% payment)

We are a team of engineer experienced in electronics, circuit design, PCB design, micro-controller programming, Arduino and wireless protocol. We have designed and developed circuits and products in the field of wearable, smart devices, home automation, power electronics, motors, IOT and sensor. We have also designed circuit for battery management system which includes battery protection, charging (wired or wireless) and over current and over-voltage. * Since we have design experience on Battery charging of Li-Poly, we can look at the current design and can build a new circuit which can charge the battery faster. In our past projects, we have worked on motor control (direction and speed) and solenoid control using microcontroller In our past projects we have done reverse engineering and redesigning work from gerbers files to produce new schematic and layout files. We also provide suggestion on BOM cost reduction and on circuit issue that may occur on long run. We are capable of designing single, double and multi-layer boards using Orcad, Altium, KiCad and Eagle tools Along with designing we also support for pcb manufacturing / fabrication and component assembly of the board. Queries: - do you have gerber files for the old design? - timeline for the project? - We are using Eagle 7.2 are you ok with this version? - Can you please share the files on chat please, since I;m unable to open the pdf ? Looking forward to work with you and for further discussion. Thank you.

What is he AH of the battery? Also the type 0.5C or 1C etc. We need to see if its physically possible by calculating it. Dimension of the board is (19mm X 96mm.) I see there are some drill holes if you have a DXF/DWG file would be helpful PDF of the dimension and position of HOLES is also OK.

Dear Sir, I have many years of Firmware development, circuit design, PCB design experience. I have used different PCB design software like Altium Designer and Eagle etc. I have also worked with battery charging circuits and have a few options we can try; please provide more information about the battery charging IC you are currently using. I will check the motor driver circuit and debug the voltage drop issue; we may have to add additional components to the motor driver to fix this? I have designed our own BLE module using the nRF51822. I can share details if you are interested. This was designed for iBeacon functionality. The module is small and uses CR2032 battery. I have created tentative milestones as per your requirements. Please contact me and we can discuss the project. Thank you Sincerely, Jatin Mehta
