Preparing Bluetooth PCB Plan.

I’ll create two Bluetooth PCBs: a wearable head‑tracking transmitter and a receiver that forwards data to a host.

Steps:
1. Capture requirements (BLE vs Classic, latency/range, battery life, form factor, receiver I/O: USB/UART or CAN with 120Ω termination).
2. Transmitter: choose BLE SoC + 6/9‑axis IMU, battery/charger, user I/O; add connections.
3. Receiver: choose BLE SoC/module + host interface (USB/UART or CAN), power; add connections.
4. Complete schematics (decoupling, programming/reset) and reviews.
5. Layout both boards with antenna keepouts; generate BOM/manufacturing files.

Click Start on the plan bar to proceed, or let me know if you want any changes.

Plan

#Goal

Develop two complete PCB schematics for the Bluetooth head-tracking system: one for the wearable transmitter board with integrated IMU and power management, and one for the Bluetooth receiver board for host connectivity.

#Implementation plan

Create two separate schematic modules within the project:
1. Establish the Transmitter schematic, including:
  1. Add a BLE SoC as the central processing unit.
  2. Include a 6/9-axis IMU block for head tracking.
  3. Integrate battery, charger, and regulator circuitry for a wearable power subsystem.
  4. Incorporate programming/debug interface and user I/O connections.
  5. Connect components where necessary to implement essential functionality.
  6. Add decoupling capacitors and other passive parts around active components as required.
2. Establish the Receiver schematic, executing the following:
  1. Add a BLE module or BLE SoC for wireless communication.
  2. Integrate a host interface using either a USB-UART conversion block or UART header design.
  3. Include power input and regulation circuitry for board operation.
  4. Connect the module components to ensure proper communication and power distribution.
Add schematic annotations:
1. Label critical nets and blocks clearly.
2. Run Electrical Rule Check (ERC) to verify connections.
Prepare for PCB layout by noting required antenna keepouts and placeholder footprints for key blocks.
Generate a Bill of Materials (BOM) based on the placeholder components added.

#Success criteria

Both the Transmitter and Receiver schematic sheets are created with complete integrated components and interconnections.
Each schematic demonstrates annotated and connected key blocks including BLE modules, sensors, power management, and interfacing elements, verified by ERC results.
A preliminary PCB layout plan is prepared including required layout constraints such as antenna keepouts and component footprint placements.

Creating a high-level plan.

You want schematics for a Bluetooth head‑tracking transmitter and a Bluetooth receiver. I’ve prepared a plan to build and show them:

Create two schematic modules: Transmitter and Receiver.
Transmitter: add BLE SoC, 6/9‑axis IMU, battery/charger/regulator, debug, user I/O; wire essentials and decoupling.
Receiver: add BLE SoC/module, host interface (USB‑UART or UART header), power; wire essentials.
Annotate nets, run ERC, prep PCB with antenna keepouts and BOM.
