A possible Ultra Wide Band featherwing
this is a wing for UWB modules - used for internal 3D positioning use cases (where GPS cant get signal). 3D position is notoriously hard to do, and these modules seem to be what most people use. we got some Qorvo https://t.cn/Rgpe2U3 DWM1000 samples mid last year and they've sorta been sitting on our sample shelf for a bit. we got a request to make a featherwing and it reminded us of this half-unfinished design. so we wrapped it up today. the module uses classic SPI, and there's 4 extra pins in case you want to use it in low power mode. thankfully there's a bunch of arduino libraries out there. now there's even a DWM3000 update, but thankfully they seem to be pin compatible. have you used UWB positioning modules successfully?

The meaning of everyone’s life is bound to be greater than that brought by love. We should gain strength and happiness via loving one person, and we’d better not use up all strength and happiness to love one person. 

每个人的人生的意义，一定要大于爱情带来的意义，我们要从喜欢一个人中获得力量和快乐，而不是用尽所有力量和快乐去喜欢一个人。—— 余秀华
