Hardware card properties ARM Cortex M4 based microcontroller LCD graphic screen 8 24 V digital input 8 24 V digital output to drive relays, lamps and alarm Motor phase voltage and current measurement, phase order determination 8 industrial 0-5 V, 0-10V, 0-20 mA, 4-20 mA analog inputs for sensors 0-20 mA analog output Buttons Status leds EEPROM for configuration data and logging USB port to transfer configuration data and logs Real time clock Hardware card properties The hardware card to be designed is an embedded system for industrial control applications. System will be used to control, configure and track the status of electric and diesel motors. The system will be ARM Cortex M4 based. Microcontroller will read data from input devices and sensors and drive relays, contactors, lamps and alarms. System will have graphic LCD screen. LCD screen may be controlled through SPI interface. Supply voltage of hardware card will be 24 V. System will read input from 8 24 V digital ports. Input data will be reported to microcontroller through ports. The system will have 8 24 V digital output ports to drive relays, contactors, lamps and alarms. Digital output ports will be operated by microcontroller. Motors will operate with 3 phase 380 V. System will be able to measure phase voltages, phase currents and determine phase order and report to microcontroller through ports. The system will have 8 industrial 0-5 V, 0-10V, 0-20 mA, 4-20 mA analog inputs for sensors. Input data will be reported to microcontroller through ports. The system will have an 0-20 mA analog output port which will be controlled by microcontroller. Various buttons on the hardware card will control card operation and menu navigation. Button data will be reported to microcontroller through ports. Hardware card will have several status leds. Leds will be controlled by microcontroller. The system will have EEPROM for non volatile storage to save configuration data and logs. The system will have USB port to transfer configuration data and logs. Real time clock feature will be provided. System will achieve EMC compliance. System will be designed with Altium. Software may be developed with Keil. Software to read and write digital input and output ports, analog input and output ports, graphic LCD, buttons, leds, EEPROM and USB port will be included. Project time 4-6 weeks maximum

I have files for a simple altimeter, but the pcb was designed a few years ago. Now there are newer and smaller barometric pressure sensors and microcontrollers, and I need to get this redesigned. I also want to add a small LCD screen for data readout and I want a micro usb port for programming. I need this to be compatible with arduino firmware and packed into the smallest board you can make. I look forward to working with you. If this job is completed successfully, I will have several more projects like this in the near future. Also, I will handle the programming myself, so this listing is for the pcb design only.
