With metal casing,The material of the aluminum substrate is very effective in processing heat diffusion in the circuit, increasing the heat dissipation effect and extending the life the aluminum alloy shell protection effectively prevents foreign matter from entering Flexible cooling,The aluminum substrate effectively handles heat diffusion in the circuit, and the heat dissipation effect is better. If greater heat dissipation is needed, you can add metal copper paste to the metal sheet for heat conduction. Wherever heat dissipation is needed, there is heat dissipation paste 168MHz CPU,The CPU uses a 168MHZ main frequency, - architecture STM32F405 with function Voltage: 14-84V Firmware upgrade: Support USB online firmware upgrade EPRM: 150000 Motor cable: 12AWG Power cable: 12AWG BEC: 5V or 1.5A output, 5V or 1.5A output for external electronic devices Support sensors: ABI, HALL, AS5047, AS5048A Communication ports: USB, CAN, UART, SPI, IIC Control mode: Support current, duty cycle, speed, position control mode Control communication method: Support PPM, ADC, , UART Current: Maximum continuous current 100A (duration depends on external heat dissipation), maximum pulse current 120A (The product appearance and printed words depending on the batch, but this does not affect use) Color: As shown Material: Metal Package Contents: 1 x Electric Speed Controller Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is 1-3cm.
