MORE INFORMATION
The upgraded F55A PROIII 4-in-1 ESC is a super ESC that features the TPHR8504 MOSFETs and is controlled by the STM32G071 microcontroller. Its stability is exceptionally high, surpassing that of previous ESCs and other products on the market.
It has added TVS protection to enhance its durability and is made with imported materials, ensuring its resilience during high-intensity flights.
It supports a wide PWM frequency range of 16-128kHz, allowing for better matching with motor parameters. The ESC also incorporates a brand-new dual oxygen dispersion heat sink design, ensuring more efficient heat dissipation and a stable power output.
