FAQ

Q: What advantages does the 1 MB Flash (STM32F103xG) offer over 512 KB variants?
A: The STM32F103RGT6 with 1 MB Flash and 96 KB SRAM is the maximum-spec F103. It provides double the Flash of 512 KB parts for massive firmware images, dual-bank firmware updates (A/B boot slots), and extensive data logging. The 96 KB SRAM comfortably runs iNav with all navigation features enabled — te

Q: How do I flash firmware to the STM32F103RGT6?
A: Flash via Betaflight Configurator (or STM32CubeProgrammer) over USB DFU: (1) Assert BOOT0 high (connect to 3.3V or press BOOT button if present). (2) Connect USB — the MCU enters the ROM serial bootloader. (3) In Betaflight Configurator select "STM32F103" as target, load the .hex firmware, click "Fl

Q: Can the STM32F103RGT6 run Betaflight 4.4+?
A: No. Betaflight dropped official F3 target support after BF 4.0.x. The STM32F103 (Cortex-M3) is classified as an F3 target. For Betaflight 4.4+, an STM32F405/F411/F722/F745/H743 (F4 or F7 target) is required. The STM32F103RGT6 remains viable for legacy Betaflight 3.x/4.0.x builds and for Cleanflight/

1. Product Overview

The STM32F103RGT6 belongs to ST's STM32F1 Performance Line — the series that defined the ARM Cortex-M3 ecosystem in the maker, hobbyist, and professional drone communities. Its combination of 72 MHz processing, extensive communication peripherals, hardware PWM for motor control, and industrial temperature range makes it the natural choice for flight controllers spanning micro whoops to professional mapping UAVs. With 1 MB of on-chip Flash — the ceiling of the STM32F103 family — the STM32F103RGT6 eliminates firmware size constraints entirely. The 96 KB SRAM comfortably runs full-featured iNav and ArduPilot builds with GPS navigation, terrain following, dual IMU redundancy, and Blackbox logging to SD card all active simultaneously. Paired with the LQFP-64 package delivering 51 GPIO, it is th
