Smart Puck PCB Design

Thanks! Here are the details to continue the design:
Antenna: Use a chip antenna (preferred) to minimize tuning effort and save board space.
Battery & Sensor Pads:
Battery pads should be located centered at the top of the PCB (aligned with the slotted post in the puck cap).
Sensor pads should be at the bottom edge of the PCB to connect to the load cell directly beneath.
Include polarized markings for both sets of pads.
3.3 V Regulation & Protection:
Yes, include a reverse current protection diode, basic LC filter, and LDO to convert from ~3.6V to 3.3V cleanly.
Target ultra-low quiescent current (<1 µA) in sleep state.
Test Pads:
Include SWCLK, SWDIO, RESET, and GND.
Optional: Add VDD pad for test/debug power injection.
Use 1.27 mm pitch for ease of pogo pin contact.
Mechanical Constraints:
Confirming: 0.6 mm PCB thickness, 2-layer board, 28 mm diameter.
Place BLE antenna clear zone at the outer right edge of the PCB.
Mark the bottom center 6 mm of the board as a keep-out zone (reserved for the Qi coil in the shell).
Please go ahead with placing components and begin sketching layout zones.

Based on the provided project description, it seems like the project is in its initial stages and currently involves two components, both of which are designated as points or pads with a single pin each, labeled P1 and P2. These could represent connection points for a power source, potentially a battery given the project title, or for any other single-pin electrical connection in a schematic. The description, however, does not specify the exact nature of these components beyond their designators and the fact that they each have one pin.
Given the title "BATTERY" and the minimal component description, one could infer that this project is intended to involve or be part of a circuit powered by a battery. P1 and P2 may represent the positive ($) + $) and negative ($) - $) terminals of a battery holder or a connector for a battery.
Without further details or additional components listed, it's unclear what the final application or function of this project will be. The lack of connections or further components suggests that this project is either an extremely simplified representation (perhaps for educational purposes, a simple demonstration, or an initial schematic creation before more detailed design work) or is at the very beginning of its design phase.
To advance this project towards completion, the following steps can be considered:
  • Defining the purpose of the project beyond simply "BATTERY", such as what it will power or be a part of.
  • Identifying the type and specifications of the battery to be used, which will help in making appropriate connections and choosing compatible components.
  • Adding components that will be powered by the battery, such as a microcontroller, sensors, LEDs, or other electronic devices, along with necessary passive components like resistors and capacitors.
  • Creating electrical connections between P1, P2, and the additional components based on the circuit requirements.
Without additional details, it's challenging to provide more specific advice or connections. However, the project presents a clean slate for a wide range of possibilities, depending on the intended application and further components that may be added.
