Hey, I am creating a smash barrier controller with ESP32 SX1276 LoRa microcontroller, and I require a 5V external power force, but I can not find anywhere which pin of 5V is the VIN one, I do not want to ruin my module, so does anyone know this particular module and which of the 5V pins is the VIN one? I have uploaded the board setup for reference purposes. If you want any extra information please let me know.

Thank You

Alex Thomas

    Hello, They are likely both connected to the Vin signal; check with a multimeter if there is continuance between the two pins if you want to make sure. Thank You Nidhi Singh

    Hi, The +20dBm specification is for chip pin output power. In any RF system, bandpass filters and RF switches have insertion loss The typical performance of the antenna can reach +19dBm after matched filtering.

    Hi,

    LoRa itself is a PHY that can be used in all network topologies. Mesh networking expands the range of the network, but reduces network capacity, At the expense of synchronization overhead and battery life reduction, due to synchronization and hop count. It is necessary to extend the distance with a mesh network architecture, so LoRaWAN chooses a star architecture to optimize network capacity, battery life, and easy installation.

    Hi, First check whether the SPI communication is successful, the successful sign is that the version value of the read chip is 0x12, the DIO0 pin is responsible for notifying the MCU that the reception is completed and check whether the DIO0 pin configuration is normal.

    Hi,

    First check whether the SPI communication is successful, the successful sign is that the version value of the read chip is 0x12, the DIO0 pin is responsible for notifying the MCU that the reception is completed and check whether the DIO0 pin configuration is normal. The configuration parameters of LoRa should be consistent, including frequency, spreading factor, bandwidth, coding rate, preamble length, frequency hopping enable, syncword, and low-rate optimization; if one of the above parameters is different, communication cannot be performed.

    Hi, LoRa defines a specific set of data rates, but there are multiple options for the end chip or PHY. SX1272 supports data rates from 0.3 to 37.5kbps, SX1276 supports 0.018 to 37.5kbps.
