This board is on the bench. Leave your email and you'll be first in when it ships, and your interest helps decide what we build next.
What you'll build
Build your own inline USB-C power meter: measure voltage and current on the high side and log or display it with an ESP32. A genuinely useful bench instrument — and you'll learn the trick that keeps a power bank from auto-shutting-off under a tiny load.
It sits on the POWER track: power delivery, including batteries, charging, protection, and the clean rails everything else depends on.
Tools for this build
Free calculators that do the math this board needs. Each is worked from a real OTD board, with the formula and a cited source.
The build pipeline
No steps skipped, no black boxes. Each stage is gated on real proof of work: a clean ERC, valid gerbers, a passing bring-up. You finish having actually done the engineering, not just watched it.
