We have official BLHeli_32 confirmation from BLHeli Developers. Let’s find out what it is about, what advantages it brings, and what changes there are moving forward. What is BLheli_32? BLHeli is an ESC firmware, and BLHeli_32 is the 3rd generation after BLHeli. BLHeli_32 is written for ‘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. Check out this article to learn about. Ever wondered if it was possible to run BLHeli Suite on Mac OS X instead of needing a.

It's smth about com.apple.driver. Benefits of BLHeli_32 Firmware on 32-bit ESC The 32bit processor on BLHeli_32 ESC has faster clock speed than the 8bit processors in BLHeli_S ESC’s. But BLHeli_S has already set the bar high for performance, it would be interesting to see how much better BLHeli_32 is than BLHeli_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 or even faster protocols! () The most exciting news about the 32-bit platform is the possibility of future functionality and features that simply wasn’t possible on 8bit ESC’s, including • programmable PWM frequency of up to 48KHz • Auto-timing for higher efficiency and realiability • Current limiting (with built-in current sensor on ESC) • Adjustable “Brake on Stop” force • Improve direction change in Bidirectional mode • ESC Telemetry • Configuring from FC using DShot commands have been reported to improve flight performance noticeably. Note that these features are just ideas from the developer (aka sskaug) at the moment and haven’t all been implemented yet. Some of these sound familiar from the. Anyway we should discover more about the new possibility as development continues. BLHeli_32 Features and Tutorials • • • Changes From Previous Firmware The previous BLHeli and BLHeli_S are open source, however the developers have decided to close source the new 32bit firmware. Their names might maintain the same prefix, but we were told BLHeli_32 has been created from scratch. (BLHeli and _S are both Assembly based while BLHeli_32 is C based) ESC manufacturers will have to pay BLHeli developers a licence fee directly to use their 32bit firmware, therefore expect some increase in ESC price. When asked why the project has become close-source, sskaug replied: From starting as a personal project to make my mCPX helicopter brushless, BLHeli as come a long way. ![]() Some of the major milestones were when we decided to pursue the multirotor segment as well, still as a hobby project, where people flashed various (non BLHeli) ESCs with BLHeli FW. Still moderate activity and efforts. But then at some point, probably starting with the Littlebee, manufacturers started making dedicated ESCs for BLHeli FW. Which I think was a major step forward for the community, as now we have a plethora of very good ESCs for multicopters. Then there was a new milestone where we decided to pursue BLHeli_S, as smoothness of BLHeli was still inferior to other ESCs in the market. And by this time we had close to 20 manufacturers doing BLHeli_S! Supporting which is actually a significant workload. So then came the next milestone – what was next?
