 - power wire connectors, as alternative to the barrel jack, for larger power supplies and usage in waterproof enclosure
 
 - proper 5V DOUT for WS2812B IC input, 5 channels (can be combined for LEDs requiring an additional clock signal)
+- in-line LED data resistors for [signal conditioning](https://quinled.info/data-signal-cable-conditioning/). Ideally it should use a smaller value since it's intended for running the signal along ground over short distances, but there were already 100 Ohm on the board for DMX512 termination, and it allows better compatibility for longer single ended cables.
 - external WiFi antenna port, by using the I variant of the ESP32-S2-WROOM, with appropriate connector
