Version History

Version 1.4.1

• Up to 35% increase in processor loop time performance, (by offloading sensor communications to the microcontroller’s Direct Memory Access Controller (DMA))
• Faster battery monitoring code
• Support for 50Hz, 400Hz and 490Hz PWM, OneShot125, OneShot42, Multishot, DShot150 and DShot300 ESC protocols
• Added timing compatibility with BLHeli_32 ESCs
• Disable ARM/DISARM transmitter switch above the minimum throttle threshold, this is to prevent inadvertently disarming the aircraft during flight
