ARDUINO ATMEGA328P BOARD PEREGRINO 2

The high-performance ATMEGA328P Microchip picoPower® 8-bit AVR® RISC-based microcontroller combines 32 KB ISP Flash memory with read-while-write capabilities, 1024B EEPROM, 2 KB SRAM, 23 general purpose I/O lines, 32 general purpose working registers, three flexible timer/counters with compare modes, internal and external interrupts, serial programmable USART, a byte-oriented Two-Wire serial interface, SPI serial port, a 6-channel 10-bit A/D converter (8-channels in TQFP and QFN/MLF packages), programmable watchdog timer with internal oscillator, and five software selectable power saving modes. The device operates between 1.8-5.5 volts.
By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching one MIPS per MHz, balancing power consumption and processing speed.

The electronics integrate a Bee socket to connect communication modules. In our store you can find GPRS, LORA and Sigfox modules among others.

La electrónica integra conexión SDI-12 para sensores, una fuente de alimentación dedicada al Bee, entradas de pulsos y conexiones para añadir otras placas de expansión como RS-485.

La electrónica puede ser alimentada por una fuente externa de 5V o por baterías.

The processor can be programmed with the Arduino development environment.
