Ich war mal wieder zu Besuch beim schnellen Ali und stöberte einwenig herum als mir dieses Board auffiel. Es besitzt einen ESP32-C3 und ist in einem Formfaktor der auf ein Breadboard passt.

What is a preview: Da ich immer mehr den Überblick über die bestellte Hardware verliere, werde ich nach der Bestellung eine kleine Vorschau schreiben. Wenn ich dann zu der Hardware komme werde ich das ensprechende Preview durch den eigentlichen Beitrag ersetzen. Somit erhaltet ihr die Möglichkeit schon mal die bald Kommende Hardware zu besichtigen und zu kommentieren. Die Beiträge werde ich dann nach euren Kommentaren oder nach meiner Laune und Zeit priorisieren ;).

• Any GPIO pin can be used as a PWM pin, and the number corresponds to that of the GPIO pin, but only 4 PWMs can be activated at the same time. Please note

LEDNumber	Corresponds to GPIO	Pin function	Description
D4	IO12	GPIO12 Configuration	Active High
D5	IO13	GPIO13 Configuration	Active High

Taster	Pin Function	** Description**
BOOT/GPIO9	When the key is pressed, the chip enters download mode	Active low
RST	When the key is pressed, the chip resets.	Active low

CH343 USB

A CH343 driver must be installed for operation via the USB port.
