DevDuino Sensor Node V2 is a compact Arduino-compatible microcontroller and is designed to build wireless networks based on transceiver nRF24L01+. This version 2.2 supports firmware upgrade over the air (based loader UNO Optiboot) and data encryption. You can easily connect other sensors or actuators to this platform, to build your remote monitoring or controlling system.
Features
- Built on Arduino-compatible architecture (UNO Optiboot)
- On board 64kb SPI flash / E2prom (for OTA firmware updates)
- On board ATSHA204A (for data encryption)
- Clock frequency - 16MHz (may be reduced to low energy consumption by up to 1MHz)
- Integrated temperature sensor MCP9700 (-40 +125 ° C, accuracy of ± 2 ° C)
- Built-in clock button
- Built-in LED (user)
- FTDI header similar to Arduino Duemilanove
- Atmel programming ISCP header
- 3 Crowtail-compatible connector: I2C, 2 - Analog, 2- Digital
- Power from 2 elements AAA (not included)
- Dimensions 32 x 68.5 mm
Package list
- DevDuino Sensor Node V2.2 x1
- nRF24L01+ Module x 1

Jargon buster
Plain-language definitions for the technical terms used above.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- OTA
- OTA means over-the-air updating, where firmware is updated wirelessly instead of through a programming cable. It matters because you may be able to update or maintain the module after it is installed in a project.
- SPI
- A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
