Hi , I have bought couple of these boards and really would like have 1 running gpios on 1V8 logic.
According to datasheet of RV1103 IOs can run at this levels.
Please can you let me know if it's possible to modify the board to run Gpios at 1V8 specifically interested to run spi Gpios at this level plus couple of other gpios
Thanks

Hello, if you want to make GPIO run at the voltage standard of 1.8V, you need to modify the hardware. By default, our hardware design directly input 3V3 to let it work at the 3V3 level standard, and it is recommended to design the level translation circuit externally

Thanks for feedback.
Will you be able to provide modifications guidance to make the board run GPIOs at 1V8?

Unfortunately I cannot use level translators as I did try few logic levels translators with pico mini b board and this approach is not suitable for my application

Thanks

The level standard of each set of GPIOs in the Luckfox Pico Mini B is set without leaving room for change, and the external level translation can refer to the scheme used by the Luckfox Pico Ultra

Thanks.
Got another question - can this boar run Flashrom? if it can can you let me know if it need to be run it on Ubuntu ot builroot OS?
Thanks

Hello, we have not tried the Flashrom tool. If you need to run this tool on the board to flash other hardware's flash memory, it should be feasible. You can enable it by checking this tool in buildrootconfig.
