FTDI FT232RQ Breakout Board with Variable LDO for VIO

Board Features:

• Capability to configure microcontrollers directly (e.g. CC430F5137)
• Configurable VCCIO between 1.8V to 5V using on-board LDO
• Data Rate Max 3,000,000 BAUD (FTDI FT232R Chip)
• Route the RTS and DTR to a header for easy mode as a Programmer
• TX and RX LED (Red/Green)
• Small form factor

 

Reflowing QFN-32 FTDI FT232RQ Chip:

First attempt to reflow a QFN-32 device to a board without purchasing expensive equipment. I used a hot air gun that I purchased on Amazon for $14 ( TruePower 01-0712 Mini Heat Gun, Blue). I also used solder paste that melts at 183C degrees.

###Applied the solder paste:

###Placed QFN-32 Device

###Final Product being used to configure a CC430F5137 microcontroller

Documents:

• Eagle_SCH_BRD_GERBER
  • Schematic, Layout and Gerber files
• FTDI_EEPROM_Configuration.xml
  • Configuration file used to configure the FT232RQ device
• Verify_Serial_Communications.py
  • Simple Python script to test the serial communications between a reference USB design and the Unit Under Test (UUT)
