Power Budget Workbench
Turn operating states into a power budget, with every measurement and assumption still attached.
Open toolSignals / power / physical consequences
Software eventually encounters electricity.
Read the pins, check the power, and measure what happened. Practical electronics for the point where a promising idea acquires wires.

All toolsBoard–Sensor Compatibility Desk
Check the supply, logic rail and address constraints before introducing the wires to each other.
Open toolField notes
All field notes3.3 volts is not a personality trait
Separate chip supply, board input, logic levels, and measured voltage before deciding two modules belong together.
Read the field noteYour battery estimate forgot the board
Build an operating-state budget and keep nominal battery arithmetic separate from measured runtime.
Read the field noteTwo sensors, one address
Read I²C addresses, pull-ups, and rise-time constraints before turning a bus problem into a firmware rewrite.
Read the field noteThe schematic gets a vote.
Sensors, boards, interfaces, and measurement methods for low-voltage bench projects. We distinguish the chip from the breakout and the calculation from the circuit you actually assembled.
