USB to Serial converter using FTDI FT230X

usb-2-serial-ftdi

This USB to serial converter project is easy to build, it is simple and inexpensive. It is based on theFT230XS from FTDI Chip.

Description

The FT230XS is outfitted in SSOP-16 packaging. The first incarnation of FT230X chips got a nasty bug when the chip inadvertently goes into suspend mode triggered by certain byte sequences.

The FT230X releases A, B and C were affected, see FTDI Chip TN_139 Technical Note. The resistor R1 connected to CBUS3 pin is providing a workaround, keeping the chip awake.

ftprog

After assembling the converter run FTProg utility to configure CBUS3 pin as Keep-Awake#.
