USB BUB 3

USB to TTL Serial Adapter The BUB III is here! It's blue, in honor of the Jee Internationale. It's tiny (2 cm × 1.6 cm × 0.7 cm) — the smallest FTDI option besides an FTDI cable. It's flexible (it can be reflashed so the LEDs indicate whatever you want). Features: Red and green LEDs show serial activity on both the TX and RX lines. Jumper pads to select between 5V and 3.3V power levels. Jumper pads to select between 5V and 3.3V logic levels. A capacitor on the DTR line to make interfacing with breadboard and DIY Arduinos easier. The output header matches the FTDI RS232 cable pinout (used by the BBB, RBBB, LilyPad, Arduino Pro, etc.), but with the added bonus of using the DTR line instead of the RTS line — just like official Arduino schematics. Default Options The BUB III ships with: 5V power option soldered by default 3.3V logic level option soldered by default This results in power (VCC) at 5V and signal logic levels at 3.3V. This works with Optiboot and Decimilia bootloaders on e
