Spedix IS30 ESC (30amp) (2-4s) (Blheli_S) (Dshot 600)
If you’re looking for insane value, incredible performance and one of the most compact ESC’s available, look no further than the Spedix IS30 ESC. While we saw an initial surge of blheli_32 purchases, its become obvious that there’s no shortage of people looking to let the technology mature a bit before adopting and in that time, we figured we’d bring in the IS30 ESC. In addition to being one of the most compact 30A ESC’s on the market, it also runs Dshot 600 without cap removal. Simply solder them up, configure as you normally would for Dshot and you’re off to the races! You may notice that these ESC’s resemble another brand’s ESC, which was shown to be a top performer for Dshot ESC’s and there’s a good reason for that. Much the way other brands came to the forefront, Spedix was the OEM manufacturer for those “other” ESC’s and has since decided to strike out on their own using the design they had been using for the “other” esc’s. In the end, the Spedix IS30 ESC won’t let you down and has quickly become the preferred ESC for FPV racing and FPV freestyle enthusiasts alike.
Dshot Highlights and advantages over other protocols include:
(if you want seriously in-depth, go HERE)
- no signal jitter.. if the FC sends 1375 the ESC will receive 1375
- high resolution (2048 steps)
- no oscillator drift (no more calibrating ESC’s)
- more robust against spikes
- safer as every singnal has a CRC (cyclic redundancy check)
- maybe later some goodies like having the ESC’s beep with the buzzer signal or things like that

If you’re looking for more info on Blheli_S, click HERE. The highlights of the Blheli_S protocol are as follows:
- BLHeli_S is an improved version of the base BLHeli code.
- BLHeli_S delivers a throttle response that is Smooth as Silk, and the main factor contributing to this, is that it uses hardware to generate motor PWM. Two MCUs support this for BLHeli_S, namely the BusyBee1 at 24MHz (EFM8BB10F8) and the BusyBee2 at 48MHz (EFM8BB21F16).
- BLHeli_S will have the same good Sync holding properties as base BLHeli. Maybe even better.
- BLHeli_S generally does Startup better than base BLHeli.
- BLHeli_S does damped light. Only.
- BLHeli_S has motor PWM that is Synchronous to the MCU master clock, as it is generated by hardware. This makes the motor Silent.
- BLHeli_S has very Small throttle Steps. The resolution varies between hardware configurations (MCU clock speed and driver type), and is between a nominal 512 steps and 2048 steps.
- BLHeli_S supports very high motor Speeds. A BB1 MCU will support 350k erpm, and the limit of the BB2 is not yet known, so the code is set to
limit at 500k erpm.
- BLHeli_S supports regular 1-2ms input signal, as well as Oneshot125, Oneshot42 and Multishot. Autodetected when the ESC sees an input signal.
