Hi I have over 10 years experience in electronic hardware design. I have designed oneself several devices and have a lot of experience with PIC microcontroller, ARM processors, Raspberry Pi, and Arduino during that period. Especially I have accumulated a lot of experience from the prototype design of various hardware devices including IoT products to the last production. PCB design on Altium Designer and Eagle CAD is no problem for me. My expertise is following: - PCB design on Altium, Eagle, and KiCAD - C/C++ programming - IoT product prototyping - Python programming - Raspberry Pi - Arduino - PIC microcontroller I think one of the most important signs of a true developer is the ability to quickly identify consumer needs and to develop products that are fully functional based on engineering technology. I will also bear in mind that the performance of the assignment is related to my honor and will always carry out the task in a sincere manner. Best Regard!
