Radiolink Pixhawk has an optimized design, improved barometer for height hold, and better noise reduction, offering slightly better performance in certain conditions.
Standard Pixhawk (depending on the version) is widely trusted, with many available peripherals and robust community support, but may lack some of the hardware optimizations of the Radiolink version.
 
The Radiolink Pixhawk and the standard Pixhawk (typically referring to Pixhawk 1 or 2) share many core features but differ in specific areas, such as hardware optimizations, stability, and additional features. Here's a detailed comparison:
 
1. PCB Layout and Design
Radiolink Pixhawk: The PCB (Printed Circuit Board) layout has been optimized to provide better flight stability, especially at high speeds. Radiolink has redesigned some aspects to improve sensor performance and reduce noise.
Standard Pixhawk: Earlier versions (like Pixhawk 1) were based on the original 3DR design. While functional, they may not have the same PCB optimizations that Radiolink claims for improved performance.
 
2. Barometer and Height Hold
Radiolink Pixhawk: Improved barometer placement for more accurate altitude hold, particularly useful in high-speed flights or when precision is needed.
Standard Pixhawk: Uses a high-quality barometer, but the placement and shielding may not be as optimized as the Radiolink version for reducing barometric noise.
 
3. Processor
Both: Both flight controllers use similar high-performance processors.
Radiolink Pixhawk: STM32F427 Cortex M4 (32-bit, 168MHz, 2MB flash, 256KB RAM).
Standard Pixhawk: Often the same STM32F427 processor, though some older versions like Pixhawk 1 may use slightly different versions of the STM32 series.
 
4. Sensors
Both: Use high-end sensors for flight control.
Radiolink Pixhawk: ST Micro L3GD20H gyroscope, LSM303D accelerometer/magnetometer, and MEAS MS5611 barometer.
Standard Pixhawk: Uses similar sensors like the Invensense MPU-6000 (gyroscope and accelerometer) and the same MS5611 barometer.
 
5. Interfaces and Connectivity
Radiolink Pixhawk: Includes multiple UARTs, SPI, I2C, CAN, and other standard interfaces. It also provides more extensive built-in support for DSM receivers, making it more adaptable for specific setups.
Standard Pixhawk: Similar in terms of interfaces but may require more peripherals or extensions depending on the model to fully utilize all connection options.
 
6. Failsafe Features
Radiolink Pixhawk: Features an automatic detection system for its interfaces, which helps ensure a successful flight control installation by detecting any bad connections.
Standard Pixhawk: Has robust failsafe mechanisms, but the installation may require manual verification of all connections.
 
7. Additional Peripherals
Radiolink Pixhawk: Comes with additional components like a buzzer, 4GB memory card, safety switch, power module, and mounting foam, providing a more complete package.
Standard Pixhawk: Typically sold with fewer accessories, though similar peripherals can be purchased separately.
