URGENT project-24 hrs: I need an Altium Designer project (schematic, BOM, and PCB layout; firmware not required): Arduino uno style board/microcontroller with USB power or battery power option that will drive 7-segment displays. Audio circuit amplifier for microcontroller to drive speaker/buzzer (1-pin). 1 PCB with 3 sections (each section will be cut and connected by ribbon cables to main section): 1 rectangular section for (qty 4) 7-segment display 1 rectangular section section for (qty 2) 7-segment display 1 rectangular section for microcontroller + circuitry Additional requirements *Source all components from Conrad Electronics (Europe) *Use surface mount components no smaller than 1206. *Use SOIC or QFP packages for the ICs if possible. Avoid QFN/BGA packages. *Use MOSFETs for 7segment display drivers instead of BJTs. *Arduino Uno style main board (Atmega328 with USB power or battery power option) *Arduino Uno has two micros, we only need one micro for this project. *Expose AVR ISP/programming header so we can program this during production using Atmel programmer or Arduino host. *Audio circuit amplifier for microcontroller to drive speaker/buzzer (1-pin, keep circuitry simple) *Design circuit to run on USB or battery power (battery will be external pack soldered to pads on main PCB) *Use this display: [login to view URL] *Use large generic SMT pads with a center hole for all switches, potentiometers, and single LEDs. (These will have wires hand soldered) *Use 0.1" thru-hole header near board edges.
