**Or long press the boot button to switch to Betaflight LED mode
1000uF Low ESR capacitor + TVS protective diode = Extra protection. The ESC is built with TVS protective diode to absorb the voltage spike when you plug in the battery, or during crashes that block your props. We also provide a humongous 1000uF low ESR capacitor, ensuring clean data from the gyro to the FC.

- No extra heat, no worries.
- 22mm cutouts for FPV camera in your tight build
*Betaflight firmware requires the type of microSD card to be either Standard (SDSC) or High Capacity (SDHC), so extended capacity cards (SDXC) are not supported(Many high-speed U3 cards are SDXC). Also, the card MUST be formatted with the FAT16 or FAT32 (recommended) filesystems. So, you could use any SD card less than 32GB, but Betaflight can only recognize 4GB maximum. We suggest you use this 3rd party formatting tool and choose ‘Overwrite format’ and then format your card. Also, check out here for the recommended SD cards.
