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
Drive real brushed-DC motors — forward, reverse, and speed control — with a DRV8833 H-bridge, commanded wirelessly over your ESP-NOW link. You'll measure the latency of a remotely-commanded actuator and run the whole thing off the rechargeable battery module you built earlier.
It sits on the ACT track: driving the physical world with motors, servos, and high-power lighting under precise control.
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.
- PCB trace width calculator (IPC-2221)Find the minimum trace width for a current at a chosen temperature rise (IPC-2221), for external or internal copper. Grounded in a real high-current board.
- Resistor power dissipation calculator (wattage rating)Find the power a resistor dissipates (P = I²R) and the smallest standard wattage rating with a 2x margin, from its current and resistance.
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.
