The Biudrone 32 70A 6S ESC is a dependable workhorse for powerful freestyle or racing FPV drones that operate on up to 6S voltage. Its robust construction and high current rating provide the performance needed for aggressive flying.
Key Features:
- High-Current Capability: Handles a solid 70A continuous current (75A peak) per motor, suitable for demanding 5-inch and larger builds operating within the 2S-6S LiPo voltage range.
- Efficient Core Processing: Powered by the AT32F421 MCU running at 128MHz for responsive and reliable motor performance.
- Quality Components: Features dependable FD6288Q three-in-one gate drivers and high-quality Murata capacitors ensuring stable operation under load.
- Durable PCB Construction: Built on a 6-layer PCB with 2oz copper thickness for effective heat management. Incorporates a high-end resin plug hole process and a user-friendly dual pad design with metallized edges to significantly reduce the risk of pads lifting during assembly or impacts.
- BLHeli_32 Firmware Ready: Compatible with BLHeli_32 firmware for advanced configuration options and performance tuning. Supports all major ESC protocols including DShot600, DShot300, DShot150, Multishot, Oneshot, etc. 1 (Note: Uses HAKRC-60-K42_Multi_32_8.Hex firmware target).
- Integrated Current Sensing: Includes an onboard current sensor (Galvanometer) with a scale ratio of 160 for monitoring power consumption in your OSD or logs.
