It's interesting to me that they have both an ESP32 and a RA4M1 processor. Is the WiFi connectivity really that intensive that they need to have both processors? I thought that was specifically why the ESP32 was a dual core design. Is the RA4M1 connected to the IO but not the ESP32? It's interesting also that they don't call out how the ESP32 is connected to the RA4M1. Depending on what that communication path is, you could be pretty limited on the amount of data that gets sent across. Overall, interesting board but I don't understand why they have the RA4M1 and don't just use the ESP32 for everything.

So it made it harder to write processor intensive tasks. The dual core of the ESP32 did away with that.
