Instructions excerpt

calc.engineer provides 82+ engineering calculators across RF, LoRa/mesh, PCB, power/solar, homelab, and general math. Tools are stateless and composable — check each tool's outputFeeds and inputFrom fields to chain calculations. For example: fspl → link_budget → snr_margin for full RF link analysis, or solar_load_audit → solar_sizing → battery_autonomy for off-grid system design. All inputs use SI units unless noted. Use the 'catalog' resource to discover tools by category.
