<![CDATA[Stamp Pico connected to ESP32 Downloader on Mac M1 Pro, nothing happens]]>I've bought the PICO DIY Kit, that contained the ESP32 Downloader. I'm securely connected the 5 pins of the Downloader to the appropriate pins on the Stamp Pico. Then I connect the USB-C cable (sync+charge) to the Thunderbolt 3 computer port. All drivers are installed. Also, no LED is lighting up on the Downloader.

osx version 14.3.1

some tips?

best regards

The device came recommended but I wouldn't be surprised if it was the stupid TB port.

I should get one of these ports!
I may be wrong ( I am wrong) about the Thunderbolt issue, so I am checking it out more thoroughly!

connected to the USBC port and never have a problem as the thunderbolt are only used for Hard drives.

The problem is that the Thunderbolt port is 'too smart'. It does not recognize the peripheral and so will not engage power.
If you have USB port on your machine try that, or a powered USB splitter. This is what I use.
