This is a short clip of my newly soldered and wired M0UKD Capacitive Touch Key plugged into an ESP32 version of the W8BH Morse Tutor.
It is very sensitive. I am accustomed to lightly touching the paddles with my fingers when keying. With this key I am not able to do that. The slightest touch sends a DIT or a DAH.
This is my first KiCad 5.0.2 schematic and PCB. I generated the Gerbers from the PCB. I sent the Gerbers for the board to OSH Park on 11 December 2019 and got them in the mail today, 27 December 2019. I am very pleased that the circuit works so well. There are a total of ten SMD components on the board. I soldered them with solder paste and a hot air gun.
My PCB mistakes include a misspelling and I forgot to make mounting holes. I can live with the misspelling, and I drilled my own mounting holes. This is my fourth homebrew Key, and my third paddle.
I ordered the ESP32 rev 2B boards from JLCPCB, and according to the tracking reports they are In-Transit. I expect a minimum of at least three weeks since I got the Economy S&H.
