Why AM32?

AM32 firmware stands out as one of the best ESC firmware options for several reasons. Firstly, AM32 is open-source, meaning it’s continually improved by a community of developers, unlike proprietary alternatives like BLHeli_32. This open approach eliminates licensing fees, which can make AM32-equipped ESCs more affordable. AM32 firmware offers advanced features such as variable PWM frequencies, bi-directional DShot, and a unique sinusoidal startup mode that delivers smoother and more efficient motor control, especially for larger motors. The firmware is highly adaptable, supporting multiple control protocols like DShot, ProShot, and PWM, making it a versatile choice for a wide range of setups.

Moreover, the transparency of open-source development allows users to inspect the source code, customize it, and even create specific targets for their hardware without needing permission from closed-source developers. This flexibility not only fosters innovation but also drives community engagement, as users can contribute directly to the firmware’s evolution. Additionally, AM32 includes built-in protections like stuck rotor protection, enhancing the overall safety and reliability of your ESCs​
