Single H-bridge, 4.5–37 V, current sense and limit
The ET-MD11 is built around the TI DRV8874 — 1 H-bridge, 4.5–37V, 6A peak, 200mΩ HS+LS, integrated current sense (IPROPI) and current regulation. It runs from VM 4.5–37V on a screw terminal; logic 3.3–5V.
Designed in Dubai by ElectroTrical — the full schematic, BOM and design notes are published below.
Good for
- Robot drive motors
- Linear actuators
- Pumps with current monitoring
