am I wrong or is the code the interesting thing here-- and not specific to this devboard? Is there anything special about this board other than it 1. looks nice 2. supports the project 3. has the requisite 8+ Mib of PSRAm 4. has a silkscreen bug?
genuinely asking as I am really still trying to figure out what i don't know about microcontrollers and embedded devices
I also looked at the schematics, which is your standard ESP devboard layout.
Edit: I'm not an expert, but have used tons of ESP based dev boards so there are a couple very frequent issues I've observed. Usually I have had trouble if the USB-UART chip is not wired correctly or doesn't reset quick enough. Lower baud rate makes it work. Also, the GPIO numbers on silk screen may not be correct, so double check those.
But, your assessment is correct... the software is definitely the interesting bit (the challenges associated with getting ClojureScript to run on that hardware, with a REPL, etc.)
The primary challenge is RAM. The (simplistic) approach I took with establishing a ClojureScript REPL is to have the standard library available, and that requires a lot more RAM than most Espruino boards have. Even with the ESP32, I had to make a few tweaks to Espruino in order to make more of the ESP32's RAM available.
Perhaps a more sophisticated approach could be devised involving "faulting in" ClojureScript standard library functions on demand as they are used, and by doing this use less RAM and reduce startup latency. If that were done, things would run on a broader range of chips (less RAM needed).
