A two-board control set for audio frequency generation and ventilated heater control.
Pair of production boards built for a thermal-acoustic test rig. The left board hosts an ESP module with two probe-style sensor inputs, a 3-pin terminal block, and a Li-ion battery tether for portable use. The right board is a smaller ventilation-and-heater controller with USB-C, indicator LEDs, and an ESP module of its own. Both boards share a common silkscreen language so they can be brought up side-by-side.
Tell me what you're building. I'll tell you what's possible.
