Power ARM/PIC with USB UART

Hey all im making a new PCB which i will use for ARM and PIC micros.
Features:
5v Supply Via USB (SMD)
3.3v Supply Via LM1117 3.3 (DPAK)
1.8v Supply Via LM1117 ADJ (SOT223)
USB to UART Via FT232RL IC (SOIC)

All powered by one 5v USB connection. Also the USB is 3v for ARM and PIC. The entire board is small too.

29.30mm x 33.62mm AKA 1.15in x 1.32in

Nice and small. It has a 8 pin port which is:
1. 5v
2. GND
3. 3.3v
4. GND
5. 1.8v
6. GND
7. TXD
8. RXD

All GNDs are tied together. Also has some caps of course to clean the supply and 2 leds for the USB 2 UART part. The LED Can be either SMD or Through Hole. I made my own eagle part to allow both on 1 pad.

Here are some pictures…
