  STM32F4  32Bit ARM micro-controller. 
◆  DRV8302 MOSFET driver / buck converter / current shunt amplifier. 
◆  12pcs NTMFS5C628NL MOSFETs. 
◆  Regenerative braking. 
◆  DC motors are also supported. 
◆  Sensored or sensorless operation. 
◆  Adaptive PWM frequency to get as good ADC measurements as possible.
◆  Good startup torque in both sensored and sensorless mode. 
◆  Duty‐cycle control, speed control or current control. 
◆  Wireless WII nunchuk (Nyko Kama) control through the I2C port. This is  convenient for electric skateboards. 
◆  Optional PPM signal output. e.g.  when controlling an RC car from a  Rasp Berry Pi or an android device. 
◆  The USB port uses the modem profile, so an Android device can be   connected to the ESC without rooting. Because of the servo output, the odometry and the extra ADC inputs(that can be used for sensors),  this is perfect for modifying an RC car to be controlled from Android  (or Raspberry Pi). 
◆  Sensored and sensorless (FOC) Field Oriented Control allows your electric skateboard to run with barely any motor noise, it auto-detects motor parameter since FW3.34. 
◆  Many safety features such as current control and temperature control features. 
◆  The motor is used as a tachometer, which is good for odometry on modified RC cars. 
◆ Adjustable protection against: 
Low input voltage 
High input voltage 
High motor current 
High input current 
High regenerative braking current (separate limits for the motor 
and the input) 
Rapid duty cycle changes (ramping) 
High RPM (separate limits for each direction). 
◆ When the current limits are triggered, a soft back-off strategy is used while the motor keeps running. If the current becomes too high, the motor is switched off completely. 
◆ The RPM limit also has a soft back-off strategy. 
◆ Commutation works perfectly even when the speed of the motor changes. This is due to the fact that the magnetic flux is integrated after the zero crossing instead of adding a delay based on the previous speed.
◆ When the motor is rotating while the controller is off, the commutations and the direction are tracked. The duty-cycle to get the same speed is also calculated. This is to get a smooth start when the motor is already spinning

  • Improper transportation, storage or installation by Buyer 

  • Modification, alteration, disassembly, repair or replace by someone other than personnel certified by Marsen Energy 

  • External influences including unusual physical or electrical stress (Lightning, flood, fire, accidental breakage, etc.) 

  • Connection to incorrect Battery, BMS, PCM or ESC. 

  • Use other than the intended use as outlined in the product description. 

3. Out of Warranty Policy 

Products damage which is not caused by seller, Marsen Energy shall provide charged service, including all the expenses of such as material cost, labor cost, warehouse cost, transportation cost, analysis cost, management cost, corporate profits, disposal expense (If necessary) and so on. 

4. Claim Payment Policy 

Claims under this Warranty must be made by notifying Marsen Energy directly. 

For a Warranty Claim to be processed, it must include following items; 

(1) Proof of the original purchase 

(2) Description of the alleged defect(s)  

(3) The relevant Product’s serial number and the initial installation date 

5. Applicable Law 

The Warranty is subject to the law of Australian State. Products come with guarantees that cannot be excluded under the Australian Consumer Law. The Buyer is entitled to a replacement or refund for a major failure. The Buyer is also entitled to have the goods repaired or replaced if the Products fail to be of acceptable quality and the failure does not amount to a major failure.
