Main features

● ARM 32-bit Cortex MCU, frequency up to 64 MHZ, 25% higher than the previous generation of MCU.

● Compared with the previous generation of ESC, the ESC ﬁrmware is optimized, makes the throttle linearity

smoother and the response faster.

● Compared with the previous generation of ESC, better routing and component layout, built in current meter.

● High performance and low ESR MOSFET , not afraid of large current.

● Wide voltage support, up to 12S liPo, suitable for x-class drone.

● Supports regular 1-2ms pulse width input, as well as Oneshot125 (125-250us), Oneshot42 (41.7-83.3us) and

Multshot (5- 25us). The input signal is automatically detected by the ESC upon power up.

All Dshot and Proshot signals are supported .

● Small size, light weight, suitable for the drone with narrow arms.

● Supports telemetry, and delivers the

digital data such as

temperature, voltage, current, speed, etc.

● The silicone twisted-pair of the throttle signal cable eﬀectively reduces the crosstalk caused by signal

transmission, and makes ﬂight more stable.

● Aluminum heat sink eﬀectively slow down the temperature rise.

● All welding requires good welding technology, short circuit between the element or the wire should be avoided

at any time.

● The shorter the welding of electrolytic capacitor pin, the better, to avoid burning oﬀ the pin with high current.

● If the current is large, it is recommended to weld two capacitors in the accessories on the ESC power supply.

or use capacitor board. It is recommended to glue and ﬁx the capacitor after welding.

● Observe polarity at all times. Check and double check before applying power.

ATTENTION

● According to personal installation method, electrolytic capacitor can be welded at diﬀerent positions, as shown

in the ﬁgure below.

Programming parameter

Programming parameters below can be accessed from the conﬁguration software (BLHeliSuite32):

1. Rampup power:

Rampup power can be set to relative values from 3% to 150%. This is the maximum power that is allowed when ramping up at low rpms and

during startup. For low rpms, the maximum power to the motor is limited, in order to facilitate detection of low BEMF voltages. Rampup power also aﬀects

bidirectional operation, as the parameter is used to limit the power applied during direction reversal. During startup, the actual applied power depends on throttle

input, and can be lower than the maximum level set by the rampup power parameter, but the minimum level is a quarter of the maximum level.

2. Motor timing:

Motor timing can be set between approximately 1° and approximately 31° in approximately 1° increments (actual accurate values here are

15/16ths of a degree).Typically a medium setting will work ﬁne, but if the motor stutters it can be beneﬁcial to increase timing. Some motors with high inductance

can have a very long commutation demagnetization time. This can result in motor stop or stutter upon quick throttle increase, particularly when running at a low

rpm. Setting timing to high will allow more time for demagnetization, and often helps.

3. PWM frequency:

Motor pwm frequency can be programmed in a range. Support variable pwm frequency where the pwm frequency is controlled by motor RPM.

-Low frequency for low throttle gives good active braking where it is most needed

-High frequency for higher throttle makes running smoother.

4. Demag compensation:

motor stop or stutter upon quick throttle increase, particularly when running at a low rpm. As mentioned above, setting high commutation timing normally helps,

but at the cost of eﬃciency. Generally, a higher value of the it gives better protection. If it is set too high, maximum power can be somewhat reduced.

5. Sine Modulation Mode:

6. Maximum Acceleration:

limited. Limiting acceleration is primarily intended as a backup parameter that can be used in cases where too hard acceleration gives desyncs. When setting to

e.g. 10%/ms, it means that the power applied to the motor is not allowed to increase by more than 10% per millisecond.

7. Motor Direction:

center throttle is zero and above is fwd rotation and below is reverse rotation. When bidirectional operation is selected, throttle calibration is disabled.

8. Startup Beep Volume:

9. Beacon/Signal Volume:

for a given time. Note that setting a high beacon strength can cause hot motors or ESCs!

10. Beacon delay:

Beacon delay sets the delay before beacon beeping starts.

11.Throttle Cal Enable:

12. Min throttle, max throttle and center throttle:

The values given for these settings are for a normal 1000us to 2000us input signal, and for the other input signals, the values must be scaled. For Dshot input

signal, these settings have no eﬀect.

13.Temperature protection:

as a support for hardware manufacturers to use, as diﬀerent hardwares can have diﬀerent tolerances on the max temperatures of the various components used.

14.Low RPM power protect:

on some low kV motors running on a low supply voltage. However, disabling it increases the risk of sync loss, with the possibility of toasting motor or ESC.

15.Low Voltage Protection:

applied to the motor if the battery voltage drops below the programmed threshold. This feature is primarily intended for ﬁxed wing crafts.

16.Current Protection:

17.Brake on stop:

Brake on stop can be set between 1% and 100%, or disabled. When not disabled, brake will be applied when throttle is zero. For nonzero

throttle, this setting has no eﬀect.

18.Auto Telemetry:

requests from the input signal.

19.LED Control:

LEDs can be controlled on ESCs that support it.

20.Stall protection:

21.Non Damped Mode：

Typical Applications

losses due to braking are counteracted by the reduced losses of active freewheeling. OFF

(For reference)

22.S.BUS:

If a valid S.BUS channel (0 to 16) is selected, then the input signal will be interpreted as S.BUS.

23. S.PORT:

If a valid S.PORT physical ID (1 to 28) is selected, then the telemetry format will be S.PORT. Note that only ESCs that use USART1 (port PB6) for

650-1000 X-Class

telemetry support S.PORT. If the "S.PORT Physical ID" programming parameter shows up in BLHeliSuite32, then your ESC supports it.

Attention

●

ESC will automatically detect the input throttle signals every time as

soon as it powered on, and then execute the corresponding signal-

receiving mode.

●

User need to calibrate the throttle range when starting to use a new

ESC or another transmitter. When the input signal is Dshot, throttle

calibration is disabled.

● Please don't ﬂash any other ﬁrmware to avoid damage to the ESC.

● Observe polarity at all times. Check and double check before applying

power.

These settings set the throttle range of the ESC. Center throttle is only used for bidirectional operation.

It can be enabled or disabled. And the temperature threshold can be programmed The programmable threshold is primarily meant

Power limiting for low RPMs can be enabled, disabled or on adaptive. Disabling it can be necessary in order to achieve full power

Low voltage protection can be set between 2.5V and 4.0V per lipo cell. Or it can be disabled. When enabled, it will limit power

Current protection can be enabled to limit current. If enabled, then current will be limited to maximum the programmed value.

When it is enabled, the ESC will autonomously output telemetry at 32ms intervals, regardless of whether or not there are telemetry

It can be set to normal or relaxed. Relaxed increases the risk of damage to ESC or motor but can recover faster when props hit obstacles.

Damped light mode is implemented by doing regenerative braking, and inherently active freewheeling is also implemented. Then
