Hello,
I tried to use the Arduino Nano IoT 33 with MAX3232 IC, but it's not working. The voltage level after connecting to the IC is 3.3V on TX and about 0.1V on RX when they should be 3.3V on both. I tried the same IC with ESP32 and works as expected, both TX and RX were 3.3V on the ESP board. I tried it with MKR1000 WiFi, and it's the same issue. Anybody encounter a similar problem or know why this is happening?
