What material is this? I’d like to cut out a hole to mount a display, but my library’s makerspace won’t put anything in the laser cutter unless they know what it is and whether it will produce toxic fumes when laser cut.
Is a 3.3V FTDI Basic required, or will a 5V connection safely drive the 3.3V Mini over the programming headers without risking damage to the board or any 3.3V devices connected to its I/O?
This seems rather obvious with the 5/3.3V silkscreening under the header, but just to be absolutely certain: I can safely program and operate this with a 5V FTDI without risking damage to the board, right? And likewise, if I’ve got it plugged into my computer over the FTDI cable, the voltage from the I/O pins will be safe for 3.3V devices even if the board itself is running from 5V USB over the FTDI connection?

Is there a dimensional diagram somewhere? I’d like to print an enclosure for this and would prefer not to have to take measurements myself if the diagram’s already out there.
e: nvm, the STLs are linked on this page.

The Kickstarter page indicates that “Voltages below 6VDC are for hackers that wish to drive the ATmega328P and LDO beyond the datasheet’s limit.” Does this mean that if I power it from a LiPO through a 5V boost converter I should expect flaky performance unless I e.g. down-clock it, or should 5V be a suitable power supply? The programmer board would be providing 5V from the USB after all…
Sounds easy enough. Thanks!
If I have an FTDI cable, can I program this over a breadboard without buying the programmer module?
No public wish lists :(
