I put together the first ESP32 rev 1 PCB today.
This is one of the boards I ordered from JLCPCB back on Nomember 19.
The PCBs arrived yesterday, after only 23 days.
Five PCBs for $8.49 incl. S&H. However that price was with a $5.00 coupon.
I made a short video of the Morse Tutor playing back a book from the SD card.

Those are the default settings. 13WPM, and 1200Hz Tone.
