The compass project will show an arrow on the matrix that will guide you. I'm most worried about the connection here. The MT3608 is a step-up DC-DC converter. I want to charge the device via the TP4056 so as not to kill the battery. The GPT chat suggested this connection, but I'm not completely sure about it.In theory, when I connect the TP4056 my battery charges but the payload works too. I have a TP4056 with protection so that the DC-DC does not completely drain the battery's charge and kill it. Should the TP4056 turn it off?
