- Navigate to “Firmware Flasher” tab.
- Select “TUNERCF405”.
- Enable “Full chip erase”.
- Click “Load Firmware (Online)” and “Flash Firmware”. Remember to use ‘diff’ for backup settings before flashing.
FLEXIBLE BUILD OPTIONS
- 5UARTs, 8 Motor Outputs, Onboard Blackbox and Current Meter Leverage the Poly F405 AIO’s multiple UARTs and interfaces for additional components like buzzers and GPS modules. Its 8 motor outputs are ideal for X8 quad enthusiasts. Advanced features like a 4MB blackbox and current meter support detailed Betaflight tuning.
ENHANCED PERFORMANCE FOR SUPERIOR FLIGHT
- F405 MCU, FD6288 Chip, Premium 20A Mosfets Experience advanced flight capabilities with the F405’s 168MHz speed and 1MB flash memory. Enable sophisticated Betaflight features without overloading the MCU. The FD6288 chip, top-tier MOSFETs, and superior heat management ensure reliable performance in extreme freestyle flying.
PRE-INSTALLED BLUEJAY FIRMWARE Bluejay, an open-source ESC firmware, comes pre-installed, offering Bidirectional Dshot and RPM filtering for improved flight dynamics. For more information, visit Bluejay’s GitHub or join their Discord community.
F405: OPTIMAL BALANCE OF FREQUENCY, MEMORY, AND IO The F405 stands out with its ample flash memory, crucial as Betaflight evolves with more features. While the 512K memory of the F411 and F722 strains under Betaflight’s demands, the F405’s larger memory benefits both developers and pilots.
Note: “IO” refers to input and output.
