Brushless DC motor controller board

Here’s a board I designed back in 2008. It’s an excessively feature-packed brushless DC motor (BLDC) controller. Bullet points: Can drive brushed and brushless (3-phase) DC motors 15~30V input voltage Single-supply operation (onboard LT3470 SMPS) 10+A per-phase current handling (Si4456DY … Continue reading
