RA-02 Breakout with Logic Level Converters
This is my attempt at fixing what I personally believe is a bad design. The Ra-02 breakout module, currently on sale, is a very basic, pin to header breakout, with very little else... Now, the Ra-02, on its own is a fantastic piece of kit, in my opinion... but the breakout board is something else completely. Users are expected to know that they need level converters, which, frankly, most of the beginners and students out there do not. Adding level converters to a breadboard environment can add a lot of messy wires, resulting in bad connections and mistakes. I decided to solve this problem for myself (as I do quite often need to get the RA-02 breakout connected to something on a breadboard, or on the bench). Making it possible to fit on a breadboard was also a requirement, which I just made possible :) The PCB has clear markings which side is 5v and which is 3v, and as an added bonus, you can keep the logic converter switched off when connecting to a 3v MCU, thus possibly saving a bit of power... ( not much, but every bit helps right... Full access to all the pins and 6 GPIO on the native RA-02 Module is provided. PCBWay did their usual good work in producing and manufacturing the PCB to my specifications, which in this case, needed to be quite small, as I wanted it to be able to fit on a breadboard. The silkscreen is easily readable, and all footprints are correctly placed. Thank you
