General issue report

I was hoping to use free pins on the ESP32-c3-lcd kit for IO

but it looks like very single pin is being used. I tried with io18 and io19 to no success as I think these are used for USB data.

Any ideas?

Hi @tomasApo, may I ask what functionality you intend to achieve using these IOs? For example, are you just looking for simple digital output?

[tomasApo]

@Lzw655 yes just looking to achieve some simple digital out like 0v and 3.3v

Since IO18 and IO19 are used for USB port which need to be connected to PC, it's not recommended to use these two IOs.
But I think you can use the following IOs:

1. IO4 (without using IR_RX/IR_TX)
2. RXD0 and TXD0 (without using UART0)
3. IO8 (the RGB LED will flash...)
