3. SWD port to get direct access to the Chipset. Diagnostics, debugging, and real time data;
4. CAN Port for CAN communication with other devices and VESC arrays;
5. COMM port for various kinds of other communication methods like I2C, ADC, Uart,You can use your Arduino or Raspberry Pi to control the VESC!
6. Sensor port for motor Hall sensors (ABI, HALL, magnetic precision encoders);
Main Components and Advantages:
1. PCB layout, size and heat dissipation It adopts a double-sided 6-layer board layout and a separate design for strong and weak electricity. The production process is 6x3oz immersion gold. Increase the MOS copper area to facilitate heat dissipation, and at the same time by adding via holes to conduct heat, the heat is transferred from the metal bottom surface of the MOS to the back surface of the PCB and to the heat sink. Compared with the traditional heat dissipation from MOS resin surface, the thermal resistance is lower and it’s conducive to work in confined spaces.
2. MOSFET: American Fairchild FDBL0150N80 ( Fairchild, which has been acquired by ON Semiconductor).
3. Driver IC: American TI company UCC27211.
This chip is also used on MTSVESC7.5H 300A 85V VESC. On 7.5H, the driver IC drives four parallel MOS without any pressure; while on 7.5R, it only drives one, which is even more fearless.
4. 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.
5. DC-DC module:
The first stage DC-DC uses TI's LM5161 to convert the main power supply voltage to 12V;
The second level of DC-DC uses Microchip's MCP16311 to convert 12V to 3.3V and 5V.
The current of the two-stage voltage conversion chip is 1A. Considering that the internal circuit needs 100ma, the external output current is controlled within 900ma.
6. CANBUS interface chip: TJA1051 of NXP Company.
7. Capacitor: 4pcs Japanese Rubycon ZLH 80V 330uf.
8. Encoder: This ESC does not integrate the AS5047 encoder chip. If necessary, please purchase the encoder board separately.
9. Firmware standard: VESCTOOL automatically recognizes this ESC as 7.5_300. This firmware can be used
Installation method and dustproof and waterproof treatment ( needs extra charges)
The standard version is without heat sink case. There are four M3 screw mounting holes on the standard version. If need, Customers need to equip themselves with heat sink and dustproof and waterproof solution when running in high current situations. It is recommended to stick the bottom surface of the ESC (the surface without components) to the heat sink. However, the indicator light on the ESC is on the component-free surface, so customers need to consider the light guide method of the indicator light.
The second version comes with a CNC aluminium case. There are mounting holes on the case and the surface components can be filled with glue (as far as possible, the customer can do it by themselves. We will charge for it if we make waterproof treatment). All components except capacitors and pins are IP66 waterproof. For the waterproof of the pins, Customers need to confirm which pins need to be connected, and potting out the pins that are not connected. The LED indicator is placed on the side of the case.
