1. What is ESP32 LoRa with Display - 863MHz-928MHz SX1276?
ESP32 LoRa with Display - 863MHz-928MHz SX1276 is a development board for IoT projects that includes an ESP32 microprocessor, a SX1276 LoRa node chip, and a 0.96-inch OLED display. It operates on frequencies between 863MHz and 928MHz and is designed for wireless communication projects. The board has a high sensitivity of about -148dBm and a power output of +20 dBm. It also includes a lithium battery charging circuit and a CP2102 USB to serial chip. The board can be used for LoRaWAN wireless communication development and other IoT projects. The main chip uses ESP32, LX6 dual-core processor, clocked at 240MHz, computing power up to 600DMIPS, chip built-in 520 KB SRAM, 802.11 b / g / N HT40 Wi-Fi transceiver, baseband, protocol stack, and LWIP, integrated dual-mode Bluetooth (traditional Bluetooth and BLE low power Bluetooth).
2. What is the transmission distance of ESP32 LoRa with Display - 863MHz-928MHz SX1276?
ESP32 LoRa with Display - 863MHz-928MHz SX1276 has a transmission distance of about 2.6 km in an open area communication environment
3. What is the LoRa transmission range indoors vs outdoors?
In open, line-of-sight outdoor environments, the SX1276 LoRa chip can achieve a transmission range of 2–5 km (depending on antenna quality and environmental factors). Indoors, typical ranges are 100–300 meters, varying based on wall density and RF interference.
4. Does this board support both 863MHz and 928MHz bands, or is a specific SKU needed?
This specific hardware SKU is designed to operate across the 863MHz to 928MHz frequency range. However, for optimal performance and compliance with local radio regulations, you must configure your software to transmit only within the legal ISM band for your region (e.g., 868MHz for Europe, 915MHz for North America/India).
