Flowcode Support Board

Hi Ben

I'm not exactly sure what I'm doing wrong.
It worked with the ESP32-wroom. With the ESP32-S3,
I can't get it to work. I've already tried three different boards.
I also noticed that the green LED is flashing.
That happened with the SparkFun board, too.

Hello,

I wonder if the LED is interfering with the signal e.g. adding capacitance and stopping the signal from running at full speed? Maybe worth removing it?

Aha I didn't know you were using my board ok I'll see if I can replicate the issue there for you and let you know. It's slightly different to the Matrix version and so there could be something minor that's causing it.

Hi Ben

This is a very practical board and works well as a data logger if there is enough space and power available.
The SD card is also located in an easily accessible place and wired in 4-bit mode.
There is just one issue with initializing the card.
