RS Components has introduced a version of its entry-level Arduino Uno wifi board for IoT projects, adding security for wireless communications.
The UK company, a trading brand of multi-channel distributor Electrocomponents, has announced availability of the Arduino board that comes with wifi wireless networking capability and more processing power than previously available, by integrating an 8bit microprocessor from Microchip.
This second version – Rev2 – of the board is functionally the same as the Arduino Uno Rev3, but also comes with built-in wifi, enabling connection to the internet, plus the addition of an onboard IMU (inertial measurement unit) sensor.
The board, which comes in the Uno’s 68.6 by 53.4mm form factor, is based around the ATmega4809 8bit processor from Microchip, which in turn integrates 6kbyte of SRAM and 256byte of EEPROM.
The board’s onboard wireless communications SoC module comes with an integrated TCP/IP protocol stack for access to wifi networks and can act as an internet access point. The module also delivers security for users, as the wifi connection is secured via the inclusion of an ECC608 crypto-chip accelerator.
The board has 14 digital input-output pins with six that can be used as PWM outputs, and six analogue inputs. Other features include a 16MHz ceramic resonator, USB connection, ICSP header, power jack and reset button.
Support for OTA (over-the-air) programming enables the transfer of Arduino sketches or wifi firmware.
With plug and plug capability, users can be quickly up and running following connection to a computer via a USB cable. The board can also be powered via an AC-DC adapter or battery.
The board is shipping from RS in the Emea and Asia Pacific regions.
RS Components offers more than 500,000 industrial and electronics products, sourced from over 2500 suppliers, and provides value-added services to over one million customers. With operations in 32 countries, it ships more than 50,000 parcels a day.
