This is the first video of my BLHeli Suite playlist. I show you how to download and install it for the next upcoming videos. Download web page - https://blhe. BLHeli / BLHeliS / BLHeli32 Programming Interface. A simple firmware that can be flashed on to your Narfduino as a programming interface for your BLHeli ESC’s. Connects to a single ESC on either pin D9 or D10, so in theory you should be able to service a single stage Brushless system without unplugging anything. To use the new Configurator, just download the archive for your platform, extract/open and run the app. There's no installer yet or auto-update features, so you'll have to retain archive contents for future use and download a new version when it comes out. Configurator is now built for all major platforms as a standalone app. Originally you had to pay to use RPM filters on BLHeliS ESC, but now it’s free thanks to BLHeliM firmware by JazzMaverick. In this tutorial I will show you how to download and flash your BLHeliS ESC with BLHeliM firmware that enables RPM filter / bidirectional DShot and 48KHz/96KHz.
BLHeli_S is a new custom ESC firmware based on the most popular BLHeli firmware – it is an improved version. Here is an overview of the new features and which ESCs support the new BLHeli_S firmware.
Improvements:
- Very smooth throttle response
- Only damped light mode
- Very small throttle steps
- OneShot 42, MultiShot
Most of the new BLHeli_S ESCs have the Silabs BusyBee 2 MCU – EFM8BB21F16. It runs at 48Mhz and just like the Silabs F39x MCU, it´s an 8bit MCU. The main factor for the smooth throttle response as well as for the synchronous motor PWM is the hardware generated PWM signal by that MCU.
The new BLHeli_S firmware is not available for F330 or F39x ESC (for now). I doubt these MCUs will be supported in the feature, cause of hardware limitations. They do support hardware generated PWM, but “can not get symmetrical deadtimes for PWM on and PWM off when you have a H/L type driver” as sskaug mentioned in the RCGroups thread.
Because of the synchronous motor PWM to the MCU master clock, the motor is very silent now. I was really amazed! It should also remove some micro vibrations, which are the multirotors worst problem.
BLHeli_S support regular 1-2ms input signal, OneShot125, OneShot42 and MultiShot. I have tested MultiShot on my XRotor 10A (F396 MC) in the last month and throttle was very smooth compared to “normal” OneShot 125. So far the only ESC, that I know to support OneShot42 was the KISS24A. Will be interested to see how the new BLHeli_S ESC will perform with my KISS FC.

Just like the standard BLHeli ESCs, you can easy flash and setup your new BLHeli_S based ESC through your flight controller using the passthrough protocol.
BLHeli_S supported ESC:
- EMAX Lightning_S 35A
- Maytech MT20A-OPTO-BK1 & MT30A-OPTO-BK1
- LittleBee 20A-S
- Racerstar MS 15A, 25A, 35A / ZTW Polaris
- Flycolor Raptor BLS
Summary: Personally I think, that the new BLHeli_S firmware and supported ESCs will massively improve your flight experience. Throttle smoothness and response are essential for a precise flight and you get these with the BLHeli_S firmware. The available ESCs are not much for now, but it is just a matter of time.
Thanks to ZTW I got some ZTW Flash 30A ESCs for tests. I am going to publish the review soon, so make sure you get the latest news by liking the Facebook page.
Update: Review, thrust and efficiency data of almost all listed BLHeli_S can be found here.
BLHeli is an ESC firmware, and BLHeli_32 is the 3rd generation after BLHeli and BLHeli_S.
BLHeli_32 is written for ESC‘s that utilize 32-bit MCU (STM32F0 Cortex-M0 at 48MHz), unlike BLHeli and BLHeli_S ESC’s that runs on 8-bit processors. BLHeli_32 does not work with 8bit Atmel or Silabs ESC’s.
With the increased in processing power, faster input signals with lower latency and higher update rate would be possible in BLHeli_32, such as Dshot1200 or even faster protocols!
