Seeeduino LoRaWAN W/GPS Dev Board

Seeeduino LoRaWAN W/GPS is an Arduino development board with LoRaWan protocol and GPS function embedded, through which you can get started quickly to experience LoRa's advantage in the field of IoT. The 4 onboard standard grove connectors allow Seeeduino LoRaWan to connect with hundreds of grove sensors and actuators for Seeeduino conveniently. As a result users are able to be more focus on the application itself without worrying about the compatibility issue between different modules. Highlighted Features Based on communication module RHF76-052AM Seeeduino LoRaWAN is compatible with LoRaWAN Class A/C Supports a variety of communication frequencies The board has embedded an integrated lithium battery management chip that allows the board to be charged by USB interface In low consumption mold, a full charged lithium battery can power the board for several months By using Seeeduino LoRaWAN W/GPS, you can build an IoT application very quickly We also offer another version that without the embedded GPS module Ultra long range of communication Ultra low power consumption Minimum current (3.7V lipo battery & remove PWR LED) Firmware upgrade available Specifications Arduino/Processor: ATSAMD21G18 @ 48MHz with 3.3V logic/power Arduino compatible (based on Arduino Zero bootloader) Embedded with lithium battery management chip and status indicator LED 20 GPIO's and 4 on-board Grove connectors 18 x PWM pins (All but pins 2 and 7) 6 x analog inputs, 12-bit ADC channels 1 x analog output (A0) 10-bit DAC 3.3V regulator with 200mA output Reset button LoRaWAN/RHF76-052: 1.45uA sleep current in WOR mode (Spec of the modules, not the board) High link budget of 160dB. -140dBm sensitivity and 19dBm Output power Dual band, 434/470MHz and 868/915MHz 19dBm@434MHz/470MHz, 14dBm@868MHz/915MHz Small size: 23mm X 28mm with 33 pin SMT package SRAM 32 KB, Flash Memory 256 KB ATSAMD21G18, 32-Bit ARM Cortex M0+ Microcontroller  UART 2 (Native and Programming) Clock Speed 48 MHz External Interrupts: All pins except pin 4 Dimensions 140mm x76mm x26mm
