I am looking for an electronic designer to enhance and complement a ready-made PSB design. Likewise, I require the design of a plastic casing to protect the circuit, with the necessary holes to make physical connections. The electronic circuit consists of:

• A source of energy. That is, an input for one or two 3.3v lithium ion batteries (as more or less current is required), with their respective space in the housing.

• A switch with its respective hole in the housing to turn the circuit on or off.

• System for recharging lithium ion batteries, with its respective hole in the housing to connect a USB cable. This system must also have a led that indicates that the battery is already charged.

• Boost type DC-DC voltage booster, which raises the voltage of the lithium ion batteries to 8 volts and provides enough current to power an Arduino nano 33 BLE.

• Amplification stage for the signals provided by 8 pressure sensors using the MCP6004 operational amplifier.

• 5 volt voltage reducer using the LM2674-5 chip, which will provide symmetrical supply voltage for the MCP6004 chip.

• Voltage inverter at -5 volts using the TPS6735 chip, which will provide symmetrical supply voltage for the MCP6004 chip.

• 3.5 mm female Jack inputs with their respective holes in the housing, to connect 8 Tekscan FlexiForce A301 111N resistive force sensors.

• A -1V reference as the conditioning voltage for 111N Tekscan FlexiForce A301 sensors, using the circuitry suggested by the sensor manufacturer.

• Arduino nano 33 BLE, to which the force sensors will be connected and will be powered by lithium ion batteries.

The design of the PSB has to be done in the PROTEUS software and at the end of the work the designer will be required to send us a copy of the PROTEUS files generated during the project.

The PSB has to be double-sided with a maximum size of 100 X 100 mm, if this is not possible the design can be divided into 2 PSBs connected by FFC / FPC jumper cables. All components have to be SMD with a size 3225 (1210), with the exception of the integrated MCP6004, LM2674-5, TPS6735 and the Arduino that will be Through Hole. All electronic elements must be available at [login to view URL]

Lastly, the shell will fit on a person's calf, therefore it must have a curve and bands to fit a person's leg.
