grizzled pivot
A small project im working on. The PCB is finished. Currently writing the WLED-usermod.
The PCB is using an ESP32 D1 Mini (it has 40 pins instead of 20 as the ESP8266 D1 Mini).
-
4 Channels (25A total, 10A per channel)
-
Every channel has independent current, power and voltage monitoring with INA219 (values get published via MQTT to HomeAssistant)
-
Relay for cutting power to LED-strips
-
Touch surface on PCB (next to LED) usable as custom button
-
SMD-1206 for easy hand soldering
-
Reverse polarity protection (P-FET)
-
Optional: INMP441 I2S Microphone with seperate low noise power supply (INMP441 standard breakout board from eBay, aliexpres, ...)
-
Optional: Line-In Audio with extension board (I2S ADC: PCM1808) -> WIP!
