Calculators

• Battery life estimator

  Build a power budget from your operating modes, estimate battery life, and see which mode is using up the battery.

  Open the calculator→
• Radio range estimator

  Work through a link budget, from transmit power to receiver sensitivity, for a rough range estimate before you build.

  Open the calculator→
• Crystal load capacitor calculator

  Pick load capacitors for a crystal from its datasheet load and your board’s stray capacitance, and check start-up margin.

• Compliance planner

  Choose your markets and what your product does, and see the approvals that usually apply and the order to work through them.

Checklists

The checks Westlake works through on its own projects. Tick items off on screen, or print a copy to mark up at the bench or in a review.

• Schematic and layout review checklist

  What to check in a schematic and board layout before you order boards: power, parts, clocks, RF, layout, EMC, thermal, DFM, test access, and release.

• First board bring-up checklist

  How to bring up a new board safely and learn the most from it: preparation, inspection, first power, clocks, debug, peripherals, RF, and power.

• Release to manufacturing checklist

  What to include and confirm before releasing a design to a board fab and contract manufacturer: data, BOM, programming, test, labels, and revisions.

• Compliance readiness checklist

  What to settle before you book a compliance test lab: markets and standards, radio approach, design checks, pre-scans, test modes, samples, and paperwork.
