ESP32 - MAX232 connection #6

Hi, first of all, many thanks for this project and your efforts. Basically I just want to let you know that the MAX232 rx / tx are wired up wrong in the given image, at least with the two MAX232 I have tested. The MAXs RX PIN needs to be connected the RX PIN of the ESP32, same for the TX Pin. The normally used tx -> rx connections applies not to the input of the MAX.

Hope this helps.

Can confirm. TX-TX and RX-RX on the TTL side.
