You have enough material and parts to make up to four of the: [**Platonic Gantry Designs**](https://gitlab.cba.mit.edu/jakeread/pgd) documented at [that link](https://gitlab.cba.mit.edu/jakeread/pgd). These look like this:

Further documentation for these things is at the page [here](https://gitlab.cba.mit.edu/jakeread/pgd): they are parametric - can be fabricated at a handful of lengths and widths - and some collection of them can be cobbled together (with well-designed mechanical appendages, or duct tape - all valid answers) to make multi-degree-of-freedom machines.
The collection of mechanical bits you have access to is as follows:

| **The Router (1)** |
| --- |
| A message passing device, this thing hooks 6 of the ATSAMD51's SERCOM USARTS up to RS-485 Differential Driver and then hooks those up to RJ10 connectors (read: phone handset jacks). It runs [ponyo](https://gitlab.cba.mit.edu/squidworks/ponyo) and you can see the [schematic, board and documentation here](https://gitlab.cba.mit.edu/squidworks/routerboard-atsamd51). |

| **The Module Board** |
| --- |
| A do-what-you-will-with-it device, this thing breaks all of the ATSAMD51's pins out to fab-lab-friendly sized castellated pins, so that you can solder it to some-circuit-of-your-design. The thing is ready to run [ponyo](https://gitlab.cba.mit.edu/squidworks/ponyo), and invites you to, indeed, write some CPP and integrate some new devices onto the network that it will happily join over that RS-485 link. [Schematic, board and documentation here](https://gitlab.cba.mit.edu/squidworks/moduleboard-atsamd51). |

| **The Steppers (4)** |
| --- |
| A motor-turning device, this thing is one of the aforementioned module-boards, soldered to a heavy duty, motor-wrastling, no-amps-barred TMC262 stepper driver which *itself* slices and dices 24v of *power* with the help of four (4!) PN-Pair mosfets (that's two whole h-bridges baby) to drive (probably) NEMA17 stepper motors, to which these things will be attached when you get them. This also runs [ponyo](https://gitlab.cba.mit.edu/squidworks/ponyo) and you can see the [schematic, board and documentation here](https://gitlab.cba.mit.edu/squidworks/moduledaughter-stepper). |

| **Power Distribution Bits** |
| --- |
| These are tiny bus-bar type devices, that should make power routing a little bit easier. Included in the kit are (1) bypass capacitors for spare charge (these are actually important for the stepper motors to work properly), (2) TVS Diodes and Bleeders, (3) 5V Regulators (also necessary) and (4) routing blocks. These are all documented and explained in [this power distribution repo](https://gitlab.cba.mit.edu/squidworks/powerdistribution). |
