What is the connection between 6 relay channel and bolt

How to connect a 6 relay channel to bolt and which type of relay should I buy 5v low or 5v high

Hi,

Firstly you can only control 5 relayes at the same time using only the Bolt WiFi module.

2ndly, it would be best to use 3.3v actiavted relays. The Bolt WiFi module control pins only provide 3.3v. They sometimes work with 5v relays as well, but it is not easy to predict.

Here is an example of a 4 Channel relay module being used with the Bolt WiFi module.

The same circuit can be extended to 6 channel relay module, but you won’t be able to use one of the relays.

Which 6 relay channel should I buy can you send me the link for the specific relay channel.

Can we use A0 pin as analog write and connect in relay .
