A small ESP32 board to drive 2 LED strips, intended to be used with WLED
Assembled, initial testing done
- Only 5V LED strips
- Works with at least 6A current
- LEDs can be powered down via FET (no relay)
- Normal fuse, no poly-fuse
- No IR receiver
- No reverse voltage protection
- No built-in USB-to-UART
- Design rules compatible with JLCPCB (because it's cheap)
- Use only parts available at Reichelt (because it's convenient)
- If possible, use widely-used parts
- SMD parts no smaller than 0603
- pin spacing at least about 1mm (SOT23-5 is about the smallest acceptable)
(Work in progress)
All ESP32-WROOM-32x modules seem to be pin-compatible.
Reichelt:
There are lots of parts that can be used here
- must be enhancement-type p-FET
- SO-8 package
- Vg(th) should be low enough that the FET is full on at ~4.5V
Reichelt:
One-gate versions of the 74xx125 will fit, but will require the pull-down resistor on pin 1 to be mounted. The selected variant must be compatible with LVCMOS input voltages, so 74HCT, 74AHCT, 74VHCT, etc.

AKL073 from Reichelt won't fit into the enclosure.
