  • To answer my own question, in case it helps others, the main differences appear to be:

    • The FT231X is a newer chip in a slightly smaller package (SSOP-20 vs. the FT232RL’s SSOP-28).
    • It’s only $2.48 for a single FT231X on DigiKey (768-1129-1-ND) vs $4.50 for the FT232RL (768-1156-5-ND)
    • The FT231X will detect USB chargers (I’m guessing via the shorted data pins); wasn’t clear if this feature enabled it to pull more than 500mA off the charger.

    Hope this helps some people!

    Can I replace the FT232R with FT231X/FT230X?

    Some more breakouts for the FT231X

  • What’re the difference between FT232RL and the FT231X breakouts? Obviously mini vs. micro USB connectors are one.

    I ask because the description for the FT231X says it’s a drop-in replacement for the FTDI basic cable. However, the Arduinos with USB based on the ATMega328PU (i.e., not the ATMega32U4 with built-in USB comms), like the RedBoard or Adafruit’s USB Boarduino, all seem to use the FT232RL instead.
