Design and build a prototype Bluetooth device

Closed Posted 7 years ago Paid on delivery
Closed Paid on delivery

I need a tiny electronic module designed with the following details:

- BLE bluetooth 4.2 connectivity

- three axis gyroscope

- three axis accelerometer

- magnetometer

- range extender for bluetooth

- microprocessor

- inductive charge receiver

- bluetooth antenna

- small power source (poly or li-ion battery)

- 4 layer PCB board

The unit needs to be smaller than 12mmx12mm. The features required are:

- record and send the data from the sensors to a paired device in packets

- have a range of at least 100 metres

- be able to transfer data while moving and spinning (transfer/connection issues to the receiving device?)

- be able to withstand high force and impacts (will be encased in silicon, but still needs to be tough).

- firmware to go with the hardware development

- inductive charging to allow the unit to be charged wirelessly (needs to be as small as possible, efficiency isn't an issue).

For more details of the use of the unit please message me to have a discussion.

hello after reviewing the project description, the size you require (12mm x 12mm) is very small. even with 4 layer board, we can not place all the components you need in a very small palce. thanks.

Dear Sir, I can help you with your project. Can propose to use Eagle for circuit and PCB layout. The only one problem that I'm completely sure that all devices that you want can't be placed on 12mm*12mm area, but if yo More
