Out of stockOverview
Two DC motors or one stepper, 2.7–10.8 V, 1.5 A per channel
The ET-MD01 is built around the TI DRV8833 — two H-bridges, 1.5A RMS / 2A peak per channel, PWM up to 50kHz, coast/brake modes. It runs from VM 2.7–10.8V (1S–2S LiPo, 4×AA, 5V USB); logic inputs 3.3V and 5V compatible.
Designed in Dubai by ElectroTrical — the full schematic, BOM and design notes are published below.
Good for
- Small robots and rovers
- Battery-powered toys and gearmotors
- Driving a small bipolar stepper
