A year ago I purchased the Raspberry Pi 4B 8GB specifically to make with the PandaPi v2.5 which was the current model at the time. Eleven months ago, the PandaPi v2.8 was released making significant improvements to the board.
Since the release of v2.8, many add-ons have been released such a the CAN board, Laser Filament Sensor, and a PT100 board. Additionally, you released the PandaZHU, and the PandaM4, but both of those only offer 32 bit support, both being based on the ESP32.
I have been continually upgrading my printer which is based on the original Rigidbot, the firmware when its made available, and OctoPi, hoping for the day that a more capable PandaPi 3 will be released. For those of us using the v2.5 board, we cannot upgrade firmware easily.
It would sure be nice if you collaborated with the author of Marlin Firmware so that a PandaPi configuration was available.
My wishes for a PandaPi are for it to continue being based on the Raspberry Pi 4B for 64 bit support, unless you created a new board with a more capable 64 bit chip, such as Raspberry Pi's RB2040. I also was the CAN interface, Laser Filament Sensor I/O, PT100 support, and any upgrades that may be in the works, native to the board.
Is there a chance that my wishes will come true in the near future?
The STM32F... chip is 32 bits versus the Raspberry Pi 4Bs 64 bits, but I have to assume that there are benefits that outweigh the loss in bit addresses.
Do you have a time frame for this new board, and does it have a name yet?
Hi, Thanks a lot for support this project! that help me to continue. yes, there will be a next version for pandapi which will replace the stm32f103cbt6 with stm32fxxx for more GPIO and sd card, and so this board can run without raspberryPi like normal printer control board.
the marlin will also update to the latest version for next pandapi and compatible with the older version hardware like pandapi2.5,2.8
