For a university project I am working on I need a recommendation for a development board. The device will be very simple and it's whole function is to connect via bluetooth to smartphone and switch on/off 2 LEDs based on commands from smartphone. Some alternatives that I looked into are Intel Edison (which is too big and powerful for this task) and cypress CY5676 (which I am not familiar with). I know there are a lot of options out there so my goal is to focus on few recommendations and compare them. Here is the full list of requirements:
- Low power (10 hours operation)
- Small size (less than credit card)
- Can be battery powered
- No external devices required for dev (such as jtag or Flash programmer)
- Can drive 2 LEDs w/o external power
- Free development tools
- Easy to connect 2 LEDs with wires (10-20cm long)
- Cheap (<$70)
- Documentation exists
