AD0505A and AD0505B are high-end PMSM FOC motor controllers (FOC ESC) for light unmanned aircraft and watercraft.

AD0505 is designed for use in propulsion systems of light unmanned aerial, underwater, and surface vehicles. The controller provides up to 1200 W of continuous power output and supports a wide range of operating voltages from 13 to 51 V (Li-ion 4–12 S).

Note that AD0505 "Myxa" ships without cables. Please add the necessary cables to your order manually.

Myxa A vs Myxa B

Myxa A is optimized for cost-sensitive systems, whereas Myxa B targets mission-critical applications.

Feature	Myxa A	Myxa B
Applications	Cost-sensitive	Mission-critical
Number of CAN bus interfaces	1 (non-redundant)	2 (doubly redundant)
BEC power output	N/A	5 V, 0.25 A (can be disabled)
Mass	26 g	27 g
Dimensions	55✕35✕19 mm	55✕35✕20 mm

Enclosure options

The following enclosure options are available. Regardless of the chosen enclosure option, all versions of Myxa are conformal-coated, which provides resilience against moisture, aggressive chemicals, corrosion, and abrasion. See the pictures for details.

Bare board (variant 0) - just the conformal-coated board-level Myxa PCB. Ideal for deeply embedded applications where size and weight are critical and the environment is well-controlled.
Polyolefin envelope (variant 1) - this transparent polymer envelope offers insulation and some protection against abrasion.
Aluminum enclosure (with an embedded heat sink, variant 2) - this option should be chosen for high-power applications, or where the device is expected to operate in a high-temperature environment with reduced convection. The aluminum enclosure provides excellent protection against mechanical damage and improved heat dissipation. The mass of the aluminum enclosure is 29 grams.

Applications

Propeller and fan drives for light unmanned aerial vehicles.
Pump and propeller drives for unmanned watercraft.
Fuel pump drives for jet engines and gas turbines.

Communication interfaces

CAN bus
RC PWM
Analog voltage or current control

AmpDrive AD0505 "Myxa" is compatible with the open Dronecode Autopilot Connector Standard.

New drop-in compatible alternatives

It is recommended to utilize AD0505C and AD0505D in new applications instead of AD0505A (originally released as Myxa A) and AD0505B (originally released as Myxa B), respectively. These are the newer motor controllers built on the same fundamental technology but with significant improvements.
