I am into DIYing a new flightcontroller, however, the microprocessors stm32f405;f765;h743, has their prices raised double or triple, and
therefore, it downed on me that if I can graft ardupilot on a esp32, which has a bigger ram, rom, and frequency.
And most importantly its far more cheaper than other mcus(just over 1£)
I know that esp32 does not have enough uart, spi nor pwms, however this can be solved by using softserial, softspi and a pca9685
If any one had tried this, please keep me informed, thx in advance.
