WLEDnano
It is a WLED controller using a ESP32-S3-MINI-1-N8 chipset and has a built in SN74HCT125DR level shifter for the LEDs. It also has a USB-C port on it so you can power it off a power bank. It is around a square inch in size. I think it would be suitable for wearable light-up costumes. It has a built in LDO to power off 5v. ONLY FOR 5V LED STRIPS!!!

Added data line resistors and EN pull-up/capacitor
I added 1206 62ohm resistors to the data lines, as shown in the WLED wiki. I also added a 1206 100nF capacitor connecting EN to GND and a 1206 size 10k pull up resistor connecting EN to VCC.

Added USB-C port and swapped MCU
I added a USB-C port so you can use it on the go and in stuff like costumes. I swapped the ESP-WROOM-32E for the ESP32-S3-MINI-1-N8 which is a smaller, newer chipset with native USB, so you can use the USB port to reflash WLED. I also removed the flashing header row because they are now obselete. I also added a boot button to pull IO0 low so you can set the esp32 to bootloader mode.
It is also 1.1 x 0.9 inches big.
