DS series Speed controller ESC is using the main control chip EMF8BB21F16G with great functional and high-performance, and special workmen ship of 8bit C8051 core,the max working frequency will be 50MHz.
Built-in automatic protection of temperature sensor.
Support Blheli_S firmware, Can easily upgrade the firmware or parameter online,also support all function of Blheli_S.
It can be programmed to set up the throttle etc.It also support two-way mode and FPV 3D mode.
Support the newest protocol of Dshot150/300/600,also PWM,Oneshot125,Oneshot42 and Multishot compatible.
With special optimize in multi-axis,the motor can launch smoother in a good throttle curve and highly support the fixed-wing and helicopter.
The twisted- pair signal wire will lower the crosstalk inside cooper wire when it transfer,which will make the flight more stable.
To adopt the new process MOSFET of low internal resistance, will help increase resistance to flow.Also,the professional MOS driver chip makes the best efficiency.
With special process -thicken PCB have lower resistance, small calorific value and bigger impact resistance current.Nice optimize layout of the components and parts makes a smaller size,lighter weight and easy to build.
