Pixhawk 248 Firmware 〈ESSENTIAL ◆〉

A defining feature of the 248 firmware is the utilization of a co-processor, the STM32F100 (IO MCU). This chip handles the direct PWM output for the main 8 channels, acting as a safety switch and fail-safe mechanism. The firmware ensures constant communication between the main Flight Management Unit (FMU) and this IO processor.

It runs the NuttX RTOS , providing a Unix-like environment for real-time tasks. Choosing Your Firmware: ArduPilot vs. PX4 pixhawk 248 firmware

While the 2.4.8 has sufficient memory for current stable releases, very large custom builds or experimental features may hit the 2MB flash limit of the STM32F427 processor. I/O Hardware: A defining feature of the 248 firmware is
