thank you for the reply. The problem is that the 5V pins have limited number of GPIO pins and I need a lot because I want to send 4 PWM signals to 4 motor drivers and connect other peripherals too (see post #6 above).
How about:
- 74HCT125 or 74LVC245 for PWM?
- BSS138 for I²C?
- TXB0108 for SPI, UART?
Based on my communication with Adafruit
or
SN74LVX245 for all signals based on my communication with Sparkfun ?
or
TXS0108E for I²C like Sparkfun suggests?
The pwm signal from Due is 1Khz and the zs-x11h (or riorand in us) controllers possibly accept 50Hz-20Khz PWM signals - there is no documentation online
I think I am lost in translation
