6. COMM port for various kinds of other communication methods like I2C, ADC, Uart. You can use your Arduino or RaspberryPi to control the VESC!
7. USB port for programing

Notice: 

• Never connect one reclever to two or more V6/V75  based SUPERFOC ESCs or VESCs in an array!  Permanent damage may result from Y-PPM wiring. 

• Only connect CAN L and CAN H ! GND pins and 5V should never be connected in a V6/V75 based SUPERFOC ESCs or VESC array.

4. Hardware:

• CNC aluminum alloy heat dissipation case, optional water cooling system and forced air cooling system.
• Separate design of strong and weak current circuit boards. The strong current MOS board is 6x3oz immersed gold, with attached 3mm² and 6mm² cross-sections copper bars  for high-current routing.
• The weak current circuit adopts the USB-Type C interface, and through EMC optimization, the USB can communicate well with the PC even when ESC strong current circuit works at high voltage and high current.
• Proprietary 5V and 12V external power supply interfaces will not cause interference when powering analog circuits such as twist/thumb throttles.
• The strong current circuit uses 24pcs FDBL0200N100 N-MOS. The theoretical instantaneous withstand current is close to 1200A! Beyond the original VESC 75V 300A!  
• Use TI UCC27211 independent Driver. The driver current is 2.5 times higher than DRV8301/8302, and the driver speed is 3 times faster. It can realize the nanosecond turn-on of the MOS tube, and improve the motor operation effect under high ERPM. The maximum ERPM can reach 140 000.
• 9pcs 80V 470uf high frequency low resistance capacitors. The capacity far exceeds other commercial VESCs on the market.
• The high-current cold-pressed terminal connection structure makes the connection more stable and less heat-generating.
• Built-in 3.3V/5V switchable power supply for Hall/Encoder. The power supply voltage can be adjusted to adapt to your Hall/Encoder board.

5. Main Components

• MOSFET: American Fairchild FDBL0200N100 ( Fairchild, which has been acquired by ON Semiconductor).
• Driver IC: American TI company UCC27211, which is also used on original 300A 75V VESC .
• Current High-Speed Sampling Chip: American TI Company INA240. It can make the current sampling faster and more accurate, and has a good improvement on the FOC and over-current protection functions.
• DC-DC module:
  The first stage DC-DC uses TI's LM5161 to convert the main power supply voltage to 12V;
  The second stage of DC-DC uses classic LM2940 to convert 12V to 5V, max supply current is 1A.
  The third stage of DC-DC uses low ripple STC2321, convert 12V to 3.3V, max supply current is 2A.
  Above power supply configuration make smoother voltage output, reducing the abnormality of MCU and other devices caused by unstable power supply.

• CANBUS interface chip: TJA1051 from NXP company.

• Encoder: This ESC does not integrate the AS5047 encoder chip. If necessary, please purchase the encoder board separately.

6.  Firmware standard:

VESCTOOL automatically recognizes this ESC MTSVESC7.5H as 7.5_300 R2. You can use this firmware.

7. Installation and proof.

The standard version comes with two mounting ears, optional cooling faucet and water pipe for water cooling. If you need a cooling fan, please install six 2510 cooling fans into the gap at the bottom of the ESC. It is recommended to use a 12V fan to increase the air volume.

The standard version is generally dustproof and waterproof. If high sealing is required, a fully waterproof version will be released later.

8. Notice before usage.

8.1 Although the 7.5H function is powerful enough, there is still heat in the case of high current application, so we must do a good job of heat dissipation! If place it in a sealed container, it must be forced to be cooled with water.

8.2 Before the new ESC is officially used, please test it with a low-voltage and low-throttle, after success, then slowly increase voltage and throttle. Be sure to pay attention to safety during this period!

8.3 Recommend to add an electronic switch with short circuit protection function between the ESC and battery, such as MTS2009AS 300A electronic switch or BMS with switch function. It is not recommended to use only contactors without short circuit protection!

8.4 The battery and motor side terminals must be connected tightly, they can’t be loose. Also please make sure terminals not touch case or other wires.  

8.5 In actual use, please use hot melt glue to fix the hall/UART interface cables the corresponding sockets of the ESC, to prevent the cables to loosen due to the bumps of the vehicle!

8.6 Please do not disconnect relay switch or electronic switch with load! Otherwise
it will cause electromagnetic interference, which might damage the VESC.

8.7. Summarize the occasions where the duty cycle mode can be used: fighting robots, differential cars, robot joint positioning, 3D printers, and model drones. Don’t use it in e-bike/etc, it’s easy to throw people away and burnt the ESC.

Currend mode is suitable for e-bike application.

8.8 If you use the VESC to work with our MTSKR1905WF remote on Esurf/ Efoil, please noted below settings:

Our remote PWM signal output pulselength in Esurf mode is 1-2ms, no brake no reverse, and in VESC default pulselength is 1ms start, 2ms end, 1.5ms center, so if you will use our remote in Esurf mode, then please adjust below settings in VESC_TOOL: 
PPM Control Type: Current no reverse
PPM Mapping: Pulselength Start: 1ms; Pulselength End: 2ms; Pulselength: 1ms

The above tips are only suggestions based on the experience of our engineers. how
to actually operate is up to you. Parameters for different setup is also different,
please noted.
