BYOD

Bring your own device to TRMNL.

Before diving into the "how," it's worth mentioning that investment required to build your own device will be greater than our retail price. We share this not to dissuade or pitch you, but as a friendly FYI. Making your own TRMNL from scratch is not an economically rational decision, but a labor of love. Our team of 9 learned this the hard fun way over a period of 7 months.

Here's what you can expect to spend per component:

• Battery, $5 (cheapest and not necessary if you prefer always plugged in)

• EPD screen, $65 (see the Waveshare 7.5" on Amazon)

• microcontroller, $3-50 (depends if you build/solder yourself or leverage a PCB prototyper)

• enclosure/case, $3-20 (design + 3D print yourself at home or use printing farm)

The lower range of each price above does not factor in the time you may spend in auto cad, or behind a soldering iron, but since we're doing this for fun let's pretend you work super fast.

Hardware requirements

At minimum, you need a micro controller... (TBD)
