Nfriedly's review was excellent. A minor mistake on the last line however...the LM317 is a POSITIVE adjustable regulator, as can be seen by the correct voltage specs, not negative as stated. Probably copied the previous line and removed the "-" signs, then neglected to change the word "negative" to "positive".

Tasmota config:

```
{"NAME":"LEDBoard RGBW","GPIO":[0,0,0,0,0,0,0,0,418,417,419,416,288,0],"FLAG":0,"BASE":18}
```

Toolchain is no longer supported and depends upon Python 2.7 which has been EoL'd for a LONG time.

It does get two stars as the price is good, and it does appear to use an open source tool chain, but I haven't actually gotten any test code functional yet.
