CNC3018 Grbl Offline Controller Ali Firmware

[jemp]

Hello, I have an offline controller for a CNC3018 Arduino Woodpecker Board, shown in pictures (source internet)
Buy playing with the firmware, I managed to brick it
Unfortunately my backup of the original firmware is lost
Does anybody has this firmware or wants to read it out
It is a STM32F103RBT6 MCU on board and can be read with STLlink v2 with the SW connections
the order is +5V, SDClck, SDIO, GND, and setting is slow speed 480khz
Tnx 4 help

It is a STM32F103RBT6

No it is not.
It is an APM32F103RBT6

The APM is mostly compatible with the STM but there are differences.

A quick search for "arduino woodpecker" gives lots of results relating to GRBL and apparently there are some versions of GRBL floating around that work for that hardware.
