Adapt the board to web builder

[Leg501]

Hello, I bought a Bolang CNC board on AliExpress. I'd like to adapt its firmware for Web Builder.

@terjeio, this board available on AliExpress for just $24(at least it what it show to me in the US).

It is most affordable grblHAL option so far. The only problem that looks like those guys didn't bother to add it into grblHAL right way, so it is impossible to use WebBuilder to make a firmware. They just packed their source code in a rar archive: https://www.bolangsk.cn/wp-content/uploads/asgarosforum/52/pico.rar

What else cool about this controller - betweenUSB and MicroSD it has connector marked as LCD which is actually UART + 5V which is perfect for my pendant project :)

@hanke-cnc This is the control board he drew. btw, he is the most persistent grblhal enthusiast in China.

I wouldn't recommend doing that. I might sell their inventory near cost price and then replace the controller with an STM32F407, as Raspberry Pi chips seem to be somewhat unstable on some users... Even then, the new motherboards could probably be sold near cost price, but some additional after-sales costs need to be considered.
