Review: These work. They are clearly labeled. The connector is no soldered, which is what I wanted. There are no LEDs on the board, also what I wanted
Review: Dachte mir trotz der anderen Kunden die es nicht zum laufen bekommen haben, dass ich es bestimmt doch hinbekomme. Tja... leider keine Chance. Beide Module weigerten sich ihren Zweck zu erfüllen. Mit dem Multimeter konnte ich auch feststellen das Kanal 1 nicht mal am Schraubterminal ankommt und angeschlossen ist. Doch selbst auf Kanal 2 war keine Kommunikation möglich. Werde beide Module daher zurücksenden. Getestet wurde mit einem Raspberry Pi 5 und einem Raspberry Pi 3 mit Raspberry OS. Die entsprechenden einstellungen wurden (Bluetooth deaktiveren, UART Terminal deaktivieren und UART an sich aktivieren) korrekt vorgenommen. Keine chance... EDIT: Upgrade von 1 Stern auf 2 Sterne Bewertung, da Treedix so freundlich war und mir ohne zu zögern den Preis erstattet hat. Habe nun bereits auch andere Module (10x Stück Pack), auch da war von bisher getesten 3 Modulen schon 1 defekt.

## Features

- This is an RS232 converter IC capaable of operating at 3V and communicating with 5V logic for TTL/CMOS projects.
- We use the SOIC package MAX3232 and disconnected all the pins needed to set the RS232 to TTL connection. And it includes the necessary five 0.1uF charge pump capacitors.
- Even when operating at a high data rate, MAX3232 can still maintain the minimum transmitter output voltage of ±5.0V required by the RS-232 standard.
- The chip has ESD protection function, supports flow control, and zero-delay automatic transmission and reception conversion. It worked like a charm and converts the signals to the proper levels.
- MAX3232 transceiver breakout board，which can replace MAX232 to complete the matching of 5V system and RS232 high-voltage interface, and also realize the interconnection of 3V low-voltage system and RS232 interface.

Ich weiß nicht, was los war, aber die haben bei mir nicht funktioniert. Zumindest habe ich aus einer RS232 Quelle keine TTL Signal bekommen. Vielleicht lag es an mir, aber ich musste die zurückschicken.
