Out of stockOverview
Three-phase brushless driver for SimpleFOC, 8–30 V
The ET-MD09 is built around the TI DRV8313 — three independent half-bridges, 2.5A peak / 1.75A RMS per phase, 250kHz PWM. It runs from VM 8–30V on this board (IC 60V; bulk cap 35V) — 3S–6S LiPo, 12V, 24V.
Designed in Dubai by ElectroTrical — the full schematic, BOM and design notes are published below.
Good for
- Gimbal and camera stabilisers
- Quiet BLDC positioning with SimpleFOC
- Reaction wheels and robotic joints
