Future Technology Devices International makes many different TTL Serial to USB chips.
One model, the FT232R, is used in boards like the
The AdaFruit FTDI friend,
SparkFun FTDI Basic,
Modern Device BUB I and
Modern Device BUB II.
It’s not the cheapest, smallest, or most functional FTDI chip– just the most popular.
Presenting the BUB III, designed around the FT231X QFN-20, a 4x4x.075 (mm) chip.
You’ll notice it has a micro-USB jack, instead of a mini-USB one. Micro-USB jacks have a bad reputation for coming off boards, because they have less surface soldered on the board. We spent a fair amount of time finding a micro-USB jack with extra prongs and adding vias to reinforce the smd pads. Our destructive testing of a few of these boards shows that our efforts to toughen up the boards were successful. The jacks take quite a bit of muscle to break, and we think they will stand up to abuse as well as mini-USB jacks.
Moving the header to the bottom makes the board even smaller, and saves us time in production.
Both LEDs are reconfigurable (should you want to reconfigure them) with FTX-prog
It’s the BUB you love, smaller, slicker and reborn with an all-new brain.
