LILYGO T3S3 ESP32-S3 LoRa Meshtastic TTGO Development Board Wireless Module with 0.96 Inch OLED Display (SX1280 2.4G with PA)

Product description product display shipping list product size product size Product description Cautions It is recommended to control the output power of the SX1280 chip between 2-5 dBm when using the SX1280 PA module, to ensure that the entire module outputs a power of 20 dBm. If the output power of the SX1280 chip is higher than 5 dBm, it will exceed the maximum allowable input for the FEM chip and cause damage. However, if the output power is lower than 2 dBm, the module's output power will still be within 20 dBm.

Therefore, the output power setting of the SX1280 chip must be carefully controlled and not exceed 2-5 dBm to avoid damaging the FEM chip. Setting the output power to 3 dBm will ensure an output power of 20 dBm. Product Pin Diagram Cautions T3 S3 is a new version of the LoRa series (formerly LoRa32 series ), which carries the SX1280 LoRa module supports the LoRa 2.4G frequency band, which supports global use, and is also equipped with the ESP32 main control chip, which supports TF cards.
