I need a bluetooth enabled "nano" arduino (google "bluno nano") with a GY-521 "built in" to the same PCB, the board should have a connection for a 3S battery (built in charger circuit via external 111-14Vdc). It should also have a built in 3 Phase BLDC motor driver similar to an ESC (electronic speed controller) sized similar to 35A (connection to motor via screw type terminal block).
There should be a terminal block tied to 3 other "digital" inputs (hall effect sensors likely) for later connections and 2 output relays capable of switching 10A.
An additional optically isolated circuit should be used to pickup high voltage pulses similar to a " hour meter / tachometer) similar to ([url removed, login to view]) and provide the pulses to one of the arduino input pins.
Please note that RS-Online has an arduino nano (non blue tooth) free PCB design and the GY-521 PCB is also available in other free PCB sites.
The design should be complete enough to transfer to a manufacturer for production.
