Hallo!
I bought a new KC868-A6 (V1.4SP) board.
I will planned work with relays and sensors (temperature and gas concentration). Programming in IDE 2.3.6 (nodeMCU-32S).
Questions.
1. Do I need to update (install firmware)?
2. How can I check the correctness of switching on/off of the relays (6 pcs) and LEDs?
3. Does the KC868-A6 V1.4SP board support UART with a supply voltage of +5 V? The Winsen Electronics ZM106, ZE16B, | MH-Z19B gas sensors that I selected require a supply of +5 V and data exchange only via UART. How can I implement this on the KC868-A6?
4. I2C does not work and cannot be diagnosed. Could this be the problem?
Thanks.
