Trying to design a great WLED board ๐๐ฆ๐ฆ
88While waiting for the turkey to finish brining, weโre designing a board for using WLED โ and we want to make like the bestest board in the whole world.
Our resident mermaid, firepixie, makes a lot of projects with WLED, and she loves it! So, how can we make something that will be powerful but not too bulky? Here are some things weโre thinking about as the design starts to congeal like cranberry sauce:
Power via USB Type C PD with a slide switch that selects between 5, 12, and 20V (24V pixels can usually run fine at 20V) OR via a 2.1mm DC jack. With ideal diodes, itโs good for up to 5A from either.
ESP32-Mini module with built-in or optional wFL antenna port. The classic โ32 has broad support, even if weโd prefer the โS2 or โS3.
There are three output signal terminal block sets, with power and ground for each. Theyโll be level-shifted to 5V.
Built in I2S microphone (weโre still pondering this one).
Stemma QT I2C port to connect external sensors/OLEDs/etc.; separate analog/digital input JST port.
1.3โณx1.75โณ / 33mm x 45mm size with mounting holes.
Anything weโre missing, anything thatโs extraneous?
