Only some thoughts on this one –
The PCB inside the Mono looks to be a custom PCB.
However, it’s widely known that Anycubic uses Chitu Systems drivers and panels
When I cracked open the Mono – I found really only 3 chips of significance…
Having a nose around ChiTu’s website found this little device – The ChiTu L M1
Have a look at page 12 / 73 and what do you spot ? – Item 8 – an ANOLOGIC EL2F Series FPGA Chip!!
Cortex®-M4 32-bit RISC core operating at a frequency of up to 168 MHz.
a GD32F307 Arm Cortex M4 controller – Cortex®-M4 Core @ 120 MHz
What this means? – No idea 😛
BUT, what this could mean…
1- The Anycubic Photon Mono board is possibly capable of using a 4K LCD
also, i’ve spotted that Chitu systems sells an ESP8266 module specifically for their boards – it could be that Anycubic plans on selling their own, or just goofed up with the polarity of the header on the board!
And, finally, after all the above, that i’m going to publish anyway, i’ve also spotted
Which looks practically identical, also has the FPGA and the ARM board and is only 2k!, D’oh!
