Anycubic Photon Mono Teardown 3

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…

An ANLOGIC FPGA – EF2L45LG144B –

and

GD32F307 Arm Cortex M4 controller

Having a nose around ChiTu’s website found this little device – The ChiTu L M1

Link to User Manual –

Have a look at page 12 / 73 and what do you spot ? – Item 8 – an ANOLOGIC EL2F Series FPGA Chip!!

AND….an STM32F407ZET6

Cortex®-M4 32-bit RISC core operating at a frequency of up to 168 MHz.

Sound familiar?

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

https://shop.cbd-3d.com/product/chitu-l-k1-controller-board-with-32bit-tmc2209-for-lcd-msla-3d-printer/

Which looks practically identical, also has the FPGA and the ARM board and is only 2k!, D’oh!
