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 (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
- OTA
- OTA means over-the-air updating, where a device's firmware is updated wirelessly rather than through a programming cable. This lets firmware be updated or maintained after a device is installed without a physical connection.
- 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.
