The MicroFTX is a low-cost, reconfigurable, and compact Micro-USB breakout board based on the FTDI FT230X full-speed USB Serial UART IC.
- USB to serial interface for microcontroller development or debugging
- Reverse-engineering tool with flexible I/O voltages (1.8V, 2.5V, 3.3V, etc)
- Battery charger detection for high-power USB applications (app note)
- Bitbang GPIO mode for simple digital input and output
