Problems with UART and Transceiver

[HanTop]

Hi, I have the MAXI POWER and I’m trying to communicate with my PC via a UART Transceiver named KYL-210. I can’t seem to either send or receive data to the controllino.

The transceivers work well(using the model and these specific transceivers for a while) and I also tried switching the RX and TX multiple times to make sure I didn’t mess it up. I also switched between the serials (tried the main serial and serial1).

I wasn’t using any libraries like SoftwareSerial, simply wrote Serial.begin(9600) and Serial.println(“a”) or Serial.write(“a”).

I would love some help,

Thanks In Advance 😀

Hi, Serial, Serial1 and Serial2 are accessible at the CONTROLLINO pin headers. At the KYL-210 you should use TTL levels. Do not forget to interconnect GND.
