Thinking deeply about your request.

Working on your request.

Your goal is now a U1 breakout board with battery reverse-polarity protection added on the 3.7 V secondary input.

I updated the plan to include:
1. Schematic revision for protected battery input
2. Through-hole input/output connectors
3. J2 tied to the 5 V primary input
4. PCB layout updates for the added protection stage

Plan

#Goal

Update the existing TPS2116 project into a breakout board design featuring a 5 V primary input, a USB port tied to the primary input, a 3.7 V lithium battery secondary input with through-hole connections, and battery reverse-polarity protection implemented with a logic-level P-channel MOSFET in an ideal-diode style.

#Implementation plan

Re-baseline Project Configuration
1. Update the project description and schematics to reflect a TPS2116 breakout board design.
2. Configure the TPS2116 (U1) to accept a 5 V primary input on VIN1 and integrate USB (J2) tied to the primary input net.
Add Through-Hole Input/Output Connectors
1. Add through-hole connectors for:
  1. Primary 5 V input
  2. Battery 3.7 V input
  3. Board output
  4. Ground
2. Update schematic connectivity to ensure proper connections between these through-hole connectors and the TPS2116.
Implement Battery Reverse-Polarity Protection
1. Add a logic-level P-channel MOSFET configured in ideal-diode style on the 3.7 V battery input path.
2. Connect and configure the MOSFET such that reverse polarity is effectively blocked while allowing proper battery functionality.
Schematic and Layout Review
1. Verify all connections follow the breakout board form factor and project requirements.
2. Check that USB, 5 V primary, and battery reverse protection circuits are correctly integrated and interfaced with TPS2116 and other components.

#Success criteria

The schematic reflects the updated TPS2116 breakout board design with clearly defined through-hole connectors for primary, battery, output, and ground.
The primary input is 5 V and the USB port is successfully tied to this net.
The secondary input accepts a 3.7 V lithium battery, and the reverse-polarity protection circuit using a P-channel MOSFET in ideal-diode style is correctly implemented.
All component connections are verified and ready for PCB layout refinement and fabrication outputs.
