FAQ

Q: What is the difference between STM32F103C8T6 and STM32F103CBT6?
A: The C8 variant has 64 KB Flash. The CB variant has 128 KB Flash. SRAM (20 KB), pinout, and peripherals are identical. Both use LQFP-48. If your Betaflight/ArduPilot build needs more code space (e.g., logging, OSD, additional features), choose the CB. Otherwise the C8 is sufficient for standard build

Q: Can the STM32F103C8T6 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+, you need an STM32F405/F411/F722/F745/H743 (F4 or F7 target). The F103 remains viable for legacy Betaflight 3.x/4.0.x builds and for Cleanflight/iNav F3 targ

Q: Is the STM32F103C8T6 affected by the 2026 MCU shortage?
A: As of mid-2026, STM32F103 supply has normalized significantly compared to the 2021–2023 shortage. Lead times are 8–12 weeks, and spot-market availability through Asia-based distributors is good. However, volume pricing has remained elevated above pre-shortage levels. Aurora Components maintains rela

1. Product Overview

The STM32F103C8T6 belongs to ST's STM32F1 Performance Line — the series that defined the "Blue Pill" development board and became the most widely cloned ARM MCU in the maker, hobbyist, and drone communities. Its combination of 72 MHz Cortex-M3 processing, rich communication peripherals, hardware PWM for motor control, and compact 48-pin footprint makes it the natural choice for entry-level to mid-range multirotor flight controllers. In the drone ecosystem, the STM32F103C8T6 is famous for running Betaflight — the dominant open-source flight controller firmware — on boards such as the Omnibus F3, SP Racing F3, Matek F405, and countless clone designs. The chip's dual 12-bit ADC enables simultaneous gyroscope and accelerometer sampling via SPI-attached IMUs (MPU6000/MPU6050/ICM-20602), while t
