Description of DFRduino Leonardo + module GSM/GPRS/GPS SIM808 - compatible with Arduino
Board is a combination of Leonardo with SIM808 GSM, GPRS and GPS module. It has a connector for microphone and speakers. Built-in system of a Lipol battery charger allows you to use the devices in portable projects. Applied sleep function saves energy. The module is ideal for a variety of IoT projects (Internet of Things).
Board is compatible with popular Arduino Leonardo.
Module GSM / GPRS / GPS SIM808
System that allows you to send text messages, to create connections in a GSM network, to transfer GPRS data and to read GPS position. Communication via serial UART interface (RX, TX) using the AT command. Board includes, i.a. a connector for SIM card, slot for microphone, and speaker.
Included is also GPS and GSM antenna.
Compatible with Arduino
Board is compatible with popular module Arduino Leonardo. The board contains an ATmega32u4 microcontroller, equipped with 20 digital inputs/outputs, 7 of which can be used as PWM outputs (e.g. to control engines) and 12 as analog inputs. The system works with the clock signal with the frequency of 16 MHz. The module also has a microUSB connector, DC power socket, RESET button, and leads that serve to connect the AVR programmer.
Creating and installing software is allowed by the free environment Arduino IDE. Implemented bootloader allows you to send the program directly via the microUSB cable. ISCP connector enables connection of AVR programmer.
