We are looking for someone to design hardware(PCB) and software of device.
Device would be remote control of our current device, and it would be connectable to it in 2 ways:
1. By wire using cable (TTL) and communication would be standards asynchronous serial communication (UART)
2. By Bluetooth
Device would need to have USB, which would be used for it's own update, and for updating our current device (BRIDGE)
Device would have graphical OLED display(probably it will be 256x64 display) with few function buttons.
On display it would be showing different states (alarms and some other messages) received from our current device, and on the other side it would send different messages to our current device. Display needs to have automatic adjustable brightness depending on the intensity of the light.
-working in design software for SCHEMATIC and PCB (P-CAD would be preferred)
-programming in C for ARM processor (preferred Keil)
-experience with Bluetooth
-creative thinking and suggestions are welcome
-prompt communication and flexibility will be important during the project development
You would need to deliver:
-SCHEMATIC and PCB layout in P-CAD
-BOM with cost estimate in Excel
-complete firmware for device
-smallest component size to be used is 0402
-device will need to be compact with small dimension footprint
Looking forward for Your quotes and ideas.
