LORA SX1276 ESP32 OLED
868MHz-915MHz SX1276 ESP32 LoRa 0.96 Inch Blue OLED Display Bluetooth WIFI Lora Kit 32 Module IOT Development Board for Arduino
If you need the document of this product,please contact us freely.
LoRa send and receive test
WIFI Kit series is the new development of the cost-effective networking program, the main chip using ESP32, LX6 dual-core processor, 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).
This product is based on the WIFI Kit 32 added SX1276 chip, that is, LoRa
™
remote modem, Applicable frequency:
868MHz -915MHz
frequency, about -148dBm high sensitivity, +20 dBm power output, high reliability, transmission distance (measured open area communication distance 2.6Km).
Onboard 32MByte Flash, Wi-Fi antenna, 0.96-inch blue OLED display, lithium battery charging circuit and interface, CP2102 USB to serial chip, the perfect support for Arduino development environment, can be very simple and fast for program verification and product development.

LORA SX1278 433Mhz
The 433MHz antenna must be used in conjunction with the IPEX interface (if the
antenna is not connected, it may damage the LoRa chip)Lithium battery charging
and discharging circuit, when the battery is full, the blue LED will stop working.
When using, pay attention to the positive and negative of the battery, otherwise
it will be damaged
！
Using the IO port touch screen touch signal input, you need to add the 100nF
pull-down capacitor at this pin!
Example:
