@mart_e Yes, I have one. For me, the main benefit is that I could follow the Ferrous Systems Training¹ precisely.

Compared to other microcontroller manufacturers, Espressif has really good Rust support, even std lib works. I don't think I had that on STM32.

Compared to other officially available ESP boards, this one has built-in charge controller and a fair set of sensors. I don't need only the IMU. There are some 3rd party boards² which have the charge controller, but I'm not sure how good they are.

Also the ESP C-series has RISC-V microprocessor architecture, so I guess if I'm gonna go lower to the processor instructions, it would be easier and more enjoyable with this board.

So, all in all I'm quite happy with the purchase, I think it's a great starting board even without considering my Rust affection :)
