Intel Edison

Edison module

Under the name Edison , Intel offers system-on-a-chip systems that are specially designed for the Internet of Things . On the module there is an Intel Quark processor compatible with the Pentium processor with a WLAN card and a Bluetooth module.

The Intel Edison series was first presented at CES 2014 and is intended to secure a place for Intel in emerging markets such as wearable computing .

On June 16, 2017, Intel announced that it would cease production and sales of the Edison series on December 16, 2017.

technology

The Intel Edison is a 35 mm × 25 mm small computer module with a 70-pin connector, whose SoC (System-on-a-Chip) is a dual-core Atom processor based on the Silvermont- Atom micro-architecture and a Quark CPU with 100 MHz clock frequency combined. The main memory is 1 GB in size, plus 4 GB of embedded flash memory for the operating system.

The Wifi chip 43340 from Broadcom uses the frequency bands 2.4 and 5 GHz in the standards IEEE 802.11 a / b / g / n, the Bluetooth module supports the standard in version 4.0. 40 GPIOs can be configured as SD card interfaces, two UARTs, two I2C, one SPI, one I ² S, one USB 2.0 OTG controller and a clock output of 32 kHz or 19.2 MHz. 12 GPIOs can be used for other purposes, 4 of them as PWMs .

The Edison requires a supply voltage between 3.3 V and 4.5 V, the power consumption in standby mode without WiFi and Bluetooth is 13 mW, with active Bluetooth 21 mW and with active WiFi 35 mW.

Boards

Intel itself has a breakout board that is only slightly larger than the Edison module itself and has soldering holes that correspond to the pins at a distance of 2.54 mm. Additionally available are a UART-to-USB bridge with USB micro type B connector, a USB OTG interface with type AB connector and a power supply (7 V to 15 V DC input) and battery connection. A second Arduino board is significantly larger. In addition to the USB interfaces of the small breakout board, it has 20 digital input / output pins (4 of which are for PWMs), 6 analog inputs, a UART, an I ² C, an SPI, and two USB 2.0 host interfaces , a micro SD card slot and the power supply connection also for 7 V to 15 V DC voltage.

Operating systems

Yocto Linux version 1.6 runs on the Silvermont cores. and a FreeRTOS on the Quark CPU . This means that Edison is real-time capable.

Prices

The Edison module together with the Arduino board costs 107 dollars, Edison alone costs 50 dollars and together with the small breakout board 75 dollars. SparkFun Electronics has already developed 14 of its own expansion modules for Edison.
