Estimate LDO power dissipation and temperature rise for STM32 boards powered from USB, battery or DC input.
This STM32 calculator helps estimate power, timing, GPIO current and ADC sampling values for embedded firmware and PCB design.
Enter STM32 current, timing, clock or analog values. The calculator returns practical estimates for early design decisions.
Useful for STM32L, STM32F, STM32G, STM32H, Nucleo boards, custom low-power boards and battery-powered sensors.
Always verify with the exact STM32 datasheet, reference manual, CubeMX settings and real current measurements.
STM32 current depends on family, clock frequency, voltage, peripherals, GPIO loads and low-power mode.
STM32L series is commonly used for low-power designs, but final choice depends on peripherals, memory and current budget.
Yes. Datasheet values are useful, but final board current depends on firmware, regulator, sensors and PCB design.
The STM32 LDO Heat Calculator is used for quick engineering estimates and early design checks. Always verify final values with datasheets, measurements and real operating conditions.
The result is an estimate based on the entered values and formulas. Real circuits can differ because of tolerances, temperature, PCB layout, losses and component limitations.
Check component ratings, voltage and current limits, thermal margin, layout, safety requirements and real measurements under load.
Runtime can be lower because of regulator losses, battery voltage sag, temperature, cutoff voltage, aging and peak current demand.
Average current is usually the most important value for runtime, especially in sleep-heavy IoT devices.
