This is confusing to me:

"How does BL602 compare with ESP32?

BL602 is a General Purpose Microcontroller that supports Bluetooth LE and WiFi

ESP32 is more of a Bluetooth LE + WiFi Controller that supports Embedded Programs"

The microcontroller in an ESP32 isn't second class or anything, and seems "general purpose" to me. So I'm confused as to what point is being made.

It does seem to be the same sentence worded slightly different. I’m curious to what the actual distinction is as well.

A difference important to some is that it is RISC-V instead of ARM. [Edit: I Am Wrong!]

ESP8266 and ESP32 (outside of that one variant with a RISC-V core) all run Tensilica Diamond Standard 106Mirco and Tensilica Xtensa LX6 cores, respectively. No ESP variant so far has had an ARM core. Which is kainda neat, but not unheard of woth embedded microcontrollers. At least it is not yet another 8051.

Amazing.

Big mystery: why did I think, all along, that ESP32 was ARM? (Don't answer that.)

The ESP32-C3 is a single-core RISC-V variant with 400kb SRAM. Not sure why I would pick the BL602 over that.

The BL602 does have an FPU, the ESP32-C3 doesn't appear to. But I imagine "more SRAM" is a bigger draw than an FPU for most use cases.
