Troubleshooting • IR receiver not getting data

After 3 hours of trial and error I still cant get a signal from my IR Reciver model.
I have a Raspbery Pi 3 running version 13.1.
I have bought this set: https://www.roboter-bausatz.de/p/infrar ... spberry-pi and i can measure a voltage drop when transmitting between the ground and data pin, but for whatever reason i dont get any signal using ir-keytable or lirc.

According to the instructions i ran it on 5V, could i have fried my GPIO by doing that?

My full firmware config:
# For more options and information see
# http://rptl.io/configtxt
# Some settings may impact device functionality. See link above for details

# Uncomment some or all of these to enable the optional hardware interfaces
#dtparam=i2c_arm=on
#dtparam=i2s=on
#dtparam=spi=on

# Enable audio (loads snd_bcm2835)
dtparam=audio=on

# Additional overlays and parameters are documented
# /boot/firmware/overlays/README

# Automatically load overlays for detected cameras
camera_auto_detect=1

# Automatically load overlays for detected DSI displays
display_auto_detect=1

# Automatically load initramfs files, if found
auto_initramfs=1

# Enable DRM VC4 V3D driver
dtoverlay=vc4-kms-v3d
max_framebuffers=2

# Don't have the firmware create an initial video= setting in cmdline.txt.
# Use the kernel's default instead.
disable_fw_kms_setup=1

# Run in 64-bit mode
arm_64bit=1

# Disable compensation for displays with overscan
disable_overscan=1

# Run as fast as firmware / board allows
arm_boost=1

[cm4]
# Enable host mode on the 2711 built-in XHCI USB controller.
# This line should be removed if the legacy DWC2 controller is required
# (e.g. for USB device mode) or if USB support is not required.
otg_mode=1

[cm5]
dtoverlay=dwc2,dr_mode=host

[all]

dtoverlay=gpio-ir,gpio_pin=2

I just thought it would be easy to replay-attack my ir controlled lamp so i could control it via my phone
