Paid on delivery
Design a LiPo Battery charger to charge two separate 3,7V LiPo (Lithium Ion) batteries from one Micro USB 5V Supply. Requirements: Schematics with routing, footprint and components in Eagle CAD. Routing is optional but preferred and a very good bonus. Part List with part numbers, preferrably from [login to view URL] or other well known suppliers. Your comments about the design. You must finish this job as soon as possible. (I need prompt and a really quick delivery starting NOW). Please take a quick look at the enclosed files for reference. (This is a quite simple and low cost project, but it will give you good possibilities for future jobs.)

Greetings, If you are okay with the schematics being in KiCad instead of Eagle, I could give you exactly what you want. In fact you are interested I can give you the layout or even assembled and working PCBs - these are not part of the bid though. I have good expertise with LiPo charges and PCB design - have done few so far - you can see on my portfolio. Let me know if kicad is fine and we can get going. T & R Alok Pugalia

Dear Client, Hope you are doing great. Thanks for the project post and providing an opportunity to bid. It is my immense pleasure to submit my proposal for this project as I am a skilled Electronics & PCB designer with more than 6 years of experience. I have appropriate knowledge and experience in Electronics and PCB designing. I can work on designs based upon new ideas, reference schematic and re-engineer circuit based upon actual PCB pics. I have worked upon several projects which includes MCU interfacing, sensor designs, accelerometer and Gyro designs, GPS/GSM designs, RF designs, Bluetooth (BLE2.0, BLE, etc), custom XBEE design, actuator interfacing, amplifier design, audio codec, memory units, USB/FTDI interfacing, battery/power management and many more similar projects As per my understanding, scope of this project is to design a PCB for parallel Lipo battery charging circuit with over-voltage protection and battey status indicators. There is variety of battery and power management options are available from Texas Instruments like BQ series. I have worked upon several similar projects in past. I will design the PCB as per size/hole requirements mentioned. Design step will have schematic update in Eagle. After that optimized routing will be done, Gerber Files will be generated. The deliverable will include source files, schematic and layout, BoM and Gerber data. Kindly revert so that I can provide my work references on similar project. Kind regards, Amit
