This is a LoRaWAN Node. It is built from ESP32-Wroom-32 and RFM95w (or SX1276). ESP32-Wroom-32 MCU is faster than UNO R3 and it comes with 4Mbit or 16Mbit Flash Memory. If you buy this product, you will get the LoRaWAN node with the power of ESP32-Wroom-32 MCU.
This node can be your wireless sensor node by connecting any sensors you like to it. Work with TheThingsNetwork and easily display your sensor data on Cayenne Dashboard. It works well with LMIC Library.
The following is included:
The others parts are shown for illustrative purposes only.
1 screw connector for I2C Sensor. 2 Groves socket (XH2.54 JST 4 Pin) for I2C Sensor. 1 Grove UART socket (XH2.54 JST 4 Pin) for GPS Module. 1 port for FTDI programming.
ESP32-Wroom-32 comes with 4Mbit or 4Mbit flash Memory. Its flash size is far more enough to run your big sketch. It is also big enough to install MicroPyton interpreter. We have tested with MicroPython v1.10. You can easily use Upycraft to install MicroPython on this board.
LoRa is a Low Power and a Long Range wireless communication (1-5 km in city and 5-15km in an urban area).
Faster development process. Work with TheThingsNetwork and easily display your sensor data on Cayenne Dashboard. Please choose your country frequency 915Mhz or 868Mhz when place an order. We will provide an antenna that is better match your freq.
You can generate source code for a few sensors by using the skecth generator Click Here

*We also provide you with a FTDI. This FTDI is slightly modified by us. We soldered RTS hole with a Male Pin Header. So, you have to connect one Dupont wire to the RTS pin header on PCB. This will make the board do automatic flash. Without connecting this wire, you still can program by manual pressing boot and reset switch.
Important Notice - This product is suitable only for an user who has a basic knowledge in Arduino IDE and C Language.
Remark - Using with GPS Module, GPS on Picture is NEO-6M. Connect pin GPS RXD to Node RX, pin TXD to TX, pin GND to GND, pin VCC to 3V3.
