I have attached a high level block diagram for what components are needed on the PCB. I am looking for a small design, about 1" by 1" that has a nordic semiconductor's NRF51822 SOC + an accelerometer and debug port. There are reference schematics for both accelerometer and the BLE chip online. There are some designs online that have same accelerometer if you are looking for inspiration for the design. One such design is here. http://get.openbeacon.org/device.html This one does not use a PCB antenna, LED and button that I want.
