To design the circuit and PCB, we used EasyEDA which is a browser based software to design PCBs.
Designing the circuit works like in any other circuit software tool, you place some components and you wire them together.
Then, you assign each component to a footprint.
Having the parts assigned, place each component. When you’re happy with the layout, make all the connections and route your PCB.
What is logic level output voltage of ESP32 (ESP32 ESP-WROOM-32 )? 5v or 3.3v?
I have to connect Lora module “REYAX RYLR998” to it, which works with 3.3v only.
logic level of ESP32 is 3.3volt and yes you can connect ESP32 directly with REYAX RYLR998.
I lost whole day but could not succeed in sending AT command using SoftwareSerial, I have ESP32 Dev Unit
SoftwareSerial lora(16, 17);
const int NETWORKID_LORA=5; //enter Lora Network ID
const int ADDRESS_LORA_NODE_GATEWAY=1;
lora.begin(115200); // default baud rate of module is 115200
delay(1000); // wait for LoRa module to be ready
lora.print((String)”AT+ADDRESS=” + ADDRESS_LORA_NODE_GATEWAY + “\r\n”);
delay(200);
lora.print((String)”AT+NETWORKID=” + NETWORKID_LORA + “\r\n”);
delay(200);
Please help
