Project details

I am expert programmer of Raspberry Pi and experienced hardware engineer .I have worked on number of projects on embedded hardware and Raspberry Pi.I have also worked on IOT based projects and peoducts development for international clients.
Currently ,I am working on Firmware for custom-built Raspberry HAT for IoT applications. I have interfaced camera and MIC with Pi. I have made custom board with Arm processor similar to Pi and this is product of Friendly Electronics named as Smart6818 .I interfaced Smart6818 with our microcontroller to get customised functionality.
I also interfaced camera with this module.
Furthermore,I am expert in switch mode power supply design to power on any hardware.
I have also made power circuit for this customised board by using low drop out and simple regulators.
I will provide quality work within short time.
More technical details can be shared after final order .
