Well, it's an $1.5 chip on $0.1 board (add $0.4 for leds, solder, ets). The rest is for manual work (assembly) and a nice margin. Anyway, if you are looking for best price, try chinese "blue pill" controller boards (<$2 a piece), they have more processing power (with similar ARM CM3 cpu). But not that nice form-factor.

The idea is to be an open source, cheap replacement for an Yubikey Nano style devices (and hopefully in response they will price their devices more reasonably than the >$50 USD it costs now). I would love what happened to the "blue pill" to happen to the Tomu board. It would be awesome for Chinese manufacturers to take the design and make cheap clones.

What does "blue pill" mean in this context?

  It’s this microcontroller board: http://wiki.stm32duino.com/index.php?title=Blue_Pill http://wiki.stm32duino.com/index.php?title=Blue_Pill They are dirt cheap and can be found for around $2 on sites like AliExpress etc.
