Linaro Connect Las Vegas 2016 is taking place right now, and the organization has some very interesting development, with a new focus on the Internet of Things thanks to the creation of LITE (Linaro IoT and Embedded) segment group that will work on “delivering end to end open source reference software for more secure connected products, ranging from sensors and connected controllers to smart devices and gateways, for the industrial and consumer markets”. The first LITE IoT Reference Platform release to be made in December 2016, but in the meantime, Linaro introduced 96Board IoT specifications, as well as the first compliant board with the launch of Carbon board (aka BLE Carbon) running Zephyr OS.
Carbon 96Boards IoT Edition board specifications:
- MCU – STMicro STM32F401 ARM Cortex M4 microcontroller @ up to 84 MHz with 512kB Flash, 96kB ram
- Connectivity – Bluetooth 4.0 LE via Nordic Semi nRF51822 SoC + chip antenna
- USB – 1x micro USB OTG port, 1x micro USB port for UART
- Expansion – 2x 15-pin Low speed connector with GPIO, UART, Analog inputs,SPI, I2C, PWM, and power signals; 3.3V I/O voltage
- Debugging – SWD debug connectors, UART console via micro USB port
- Misc – 6LEDs ( USR1, USR2, BT, PWR, RX, TX), 2x push buttons (BOOT0 and RESET)
- Power Supply – 5V via micro USB port with fuse protect
- Dimensions – 60 x 30 mm as per 96Boards IoT standards
As with other 96Boards specifications, 96Board IoT Edition (IE) specification defines requirement for multiple revision of boards either using Cortex-A or Cortex-R/M profile, and IE standard (60x30x9mm) or IE Extended (85x54x12mm) form factor. On top of that you’ll also have board with 3.3V I/Os, and others with 1.8V I/Os. That means that BLE Carbon board is compliant with “96Board IoT Edition standard using Cortex-R/M profile and 3.3V I/Os“.
The specifications also mandates at least one wireless interface such as Zigbee and Bluetooth LE, as well as optional Ethernet, USB, and micro SD card support.
Seeed Studio is now taking pre-orders for the BLE Carbon board for $27.95 with shipping planned for October 20th.
