Neokey 1x4 not found on i2c bus

Post by pilottrack »

Hello,

My NeoKey 1x4 is not showing up on the i2c bus.

I've tried on both an RP2040 Pico, and a Raspberry Pi 4. Other devices on the i2c bus do show up, both before and after the NeoKey on the bus. I am using the Adafruit i2c scanner code on the Pico.

Code: Select all

Scanning...
I2C device found at address 0x3D  !
I2C device found at address 0x52  !
done
0x52 is an RTC module before the NeoKey, and 0x3D is an OLED display on the bus after.

The NeoKey 1x4 power led does comes on, as does the power led on the next device, the OLED display.

I don't see any missing components on the board as reported in this forum thread: viewtopic.php?p=965450#p965450

If I replace the NeoKey with my LED Arcade Button 1x4 device, the Arcade 1x4 does appear on the bus.

Is there anything I missed while trying to use the NeoKey?
