LilyGO T-Lora C6 ESP32-C6 LoRa SX1262 Dev Board

Install the Arduino ESP32 board support via the Boards Manager. Then, add the required LoRa library, such as Sandeep Mistry's or the RadioLib library. Select 'LilyGO T-Lora C6' or a Generic ESP32-C6 board, define your frequency (868E6 or 915E6), and use the library's API to initialize the SX1262, send, and receive packets. Ensure your code handles the specific GPIO pins connected to the SX1262's SPI and control lines as defined in the board's schematic.

The board's deep sleep current is dominated by the ESP32-C6's low-power mode and the quiescent current of the SX1262 and supporting circuitry. With the ESP32-C6 in deep sleep and the SX1262 powered down, expect currents in the range of 10s to 100s of microamps. For periodic LoRa transmissions, you must wake the ESP32-C6, power and configure the SX1262, send the packet, and then return to deep sleep. Average current depends heavily on transmission interval, payload size, and spreading factor.

Yes, the ESP32-C6 and SX1262 are independent peripherals. You can design firmware where the ESP32-C6 connects to a Wi-Fi network for cloud communication or acts as an access point while simultaneously using the SX1262 to send or receive LoRa packets. This is managed through multitasking or in a sequential loop. Ensure your power supply can handle the combined peak current draw when both radios are active, especially during Wi-Fi association and LoRa transmission.

The board likely has an integrated PCB trace antenna or an IPEX/u.FL connector for the SX1262. Check the board's physical layout for a small, surface-mount connector. If an IPEX connector is present, you can attach a compatible 868/915MHz LoRa antenna with a matching pigtail cable. Ensure the antenna is tuned for your operating frequency (868MHz or 915MHz) for optimal range and efficiency. Never transmit without an antenna or a proper dummy load connected.
