Looking back, the FPV hobby has been through so many ups and downs. Yeah, I feel like ranting a bit…When COVID hit in 2020, along with shifting international relations, we saw an STM32 chip shortage. Experts claimed it was just a simple supply-and-demand issue. But years later, we can see that AT32 chips have taken over a significant portion of STM32’s market share. Many ESCs and other microcontroller applications are now dominated by AT32 – not entirely, but substantially. Don’t get me wrong, this outcome isn’t necessarily bad. I’m just saying the chip shortage period was a really unsettling experience for FPV.Then there’s the MPU6000 gyro being discontinued – we never got a perfect replacement. Even though Betaflight and Fettec have made big improvements in ICM gyro support, it’s still a huge loss for high-performance freestyle quads. Nobody cares about FPV; our market is just too small.The war led to BLHeli32 shutting down development – another massive blow to FPV. Manufacturers had to switch to AM32. I know BLHeli32 isn’t completely gone, but development has stopped. And I’ll say it outright: AM32 ESCs with ICM gyros are a disaster. Thankfully, if you want top-tier ESC performance, Fettec is an option – expensive, but performance-wise it definitely holds up against BLHeli32. I’m talking about freestyle here; for racing you’ll need to test it yourself. Of course, ICM gyros on Fettec flight controllers perform the same as on Betaflight – still not matching the MPU6000.There are rumors that Rapidfire’s new version under Orca isn’t as good as the original. I haven’t verified this myself – hopefully it’s not true.That’s all I can think of for now. Really hope the FPV hobby gets the attention and protection it deserves.
回首过去，FPV运动经历了太多的坎坷。是的，我又想逼逼了。。2020年随着covid的开始，以及国际关系发生的变化，stm32出现了芯片短缺潮。专业人士认为这仅是供小于求的原因造成的。多年后的今天我们发现亚特力已经替代了stm32相当一部分的市场，很多电调包括其它用途的单片机都已经是亚特力的天下了，尽管这不是绝对的情况。当然这个结果并没有什么不好，我只是想说FPV经历的芯片短缺潮这段时期是一个令人不安的经历。姿态传感器，MPU6000停产，我们没能有完美的替代品。尽管最新的Betaflight和Fettec 都对icm的支持有了较大的进步，但是对于高性能的穿越机来说还是一个巨大的遗憾。没有人关心FPV，它的市场太小了。战争，BLHeli32关闭了项目，这是另外一个巨大的冲击对于FPV来说。厂商们不得不转向AM32，我知道bl32并没有完全消失，但它已经停止了开发。我可以大言不惭地说am32电调搭配ICM传感器是一个灾难。幸运的是，如果你想要最高性能的电调，可以考虑fettec，虽然它很贵，但是性能绝对不在bl32之下。我说的是花飞应用，能否满足竞速的需求需要自己测试。当然，icm传感器在Fettec飞控上的情况和betaflight 一样，不会超过MPU6000的性能。Rapidfire 被Orca收购后推出的新版接收机据说，没有之前的性能强劲，这个情况我没有亲自验证，但愿不是真的。暂时想起来这么多，希望FPV运动可以得到重视和保护。
