Hardware - Pro Micro

This section covers the required hardware for users who have chosen the Pro Micro.

Required Hardware

  1. Pro Micro Board
  2. Micro-USB male to USB-A male cable or adapter. (example 1, example 2)

Adapters for Micro-USB male to USB-A male are notoriously difficult to find in quantity. Cables are easy to find, but less convenient if you just want to plug them into the standing Switch dock.

The basic Pro Micro hardware setup will look like this:

  1. Switch Lite users will also need a USB hub or portable dock. (example)

The Switch Lite does not have a USB-A port. Therefore you need either an adapter or a hub to connect the microcontroller. A charging hub or dock is required to simultaneously charge and use the microcontroller.

Note: even on a dock, Switch Lite cannot output video over HDMI.

Serial Hardware for Computer-Controlled Programs

If you only need microcontroller-only programs, skip this section.

  1. Serial Board (Pick one)
    1. UART Cable (CP210x controller) Adafruit UART cable is not the cheapest, but it is the most beginner-friendly.

      DO NOT get the Prolific (PLxxxx) controllers. They do not work and they are explicitly blocked in the program.

      They are cheap because they do not work. If you buy it anyway, you will be wasting your time and money.

      YOU HAVE BEEN WARNED!

    2. CP210x board (4 for $8) | (2 for $8) | (1 for $8)

      If you are experienced (or confident), these are some cheaper alternatives which also work. These may require a trivial amount of extra wiring.

  2. Board Connection (Pick one)
    1. Mini-Grabber to Male jumper wires (example)

      Easiest option, but item is hard to find

    2. Solderless Hammer Headers (example)

      Fairly easy to install. Ensure you are getting hammer headers, they will have a bulge on the short side to hold the pins in place

    3. Headers (example)

      Most difficult option! You will need to solder with this option. Please only pick it if you are comfortable soldering.
