RadioMaster TX12 MKII ELRS
New processor new capabilities RadioMaster TX12 MKII ELRS
The RadioMaster TX12 MKII ELRS is equipped with a modern STM32F407 processor, which provides significantly better performance and speed compared to the previously used STM32F207. It features a faster ARM Cortex-M4 core with a Floating Point Unit (FPU), allowing for improved processing of floating-point operations, an enhanced clock speed of up to 168MHz, increased RAM capacity of 192KB, and support for a hardware graphics accelerator. Additionally, it has more advanced peripherals, such as DMA2D, USB OTG HS with full PHY support, and additional camera interfaces.
As a result, the RadioMaster TX12 MKII ELRS operates much more efficiently, providing you with a more responsive experience and better control over your model. With its increased computational power, it fully supports the modern ExpressLRS protocol, which operates at refresh rates of up to 1000Hz, offering a more stable signal and greater range. The new processor also contributes to better energy management, translating to longer operating times on a single charge. Consequently, the RadioMaster TX12 MKII ELRS is a tool that will satisfy both enthusiasts and professionals looking for reliable equipment for their RC models.
