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
A DC electronic load sinks a programmable, constant current so you can test power supplies, batteries, and chargers under real demand. You'll build the op-amp + MOSFET constant-current loop, manage the heat it dumps, and set the current — with live telemetry — from an ESP32.
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.
