Mixtile GENA is a Wearables Development Kit Inspired by Pebble Watch

The first Pebble watch with a black and white e-Ink display and Bluetooth for smartphone connection launched in 2012 via Kickstarter, and it  became one of the most successful crowdfunding campaigns so far. The watch can now be purchased for $100, but Focalcrest, a startup based in Shenzhen, designed Mixtil GENA development kit with similar features and user interface, although with different electronics components, that goes for $34 on Tindie. Mixtile GENA specifications: Processors Mediatek MT6260 ARM7EJ-S processor @ 364 MHz with 8MB RAM and 16MB Flash Nordic Semiconductor nRF51822 ARM Cortex M0 Bluetooth Smart SoC External Storage – micro SD card slot (Up to 8GB) Display – “Energy-saving” reflective LCD Connectivity – Bluetooth 4.0 LE USB – micro USB 2.0 port Sensor – Gravity sensor Misc – Up, Down, Enter and Power/Return buttons Battery – 270 mAh/3.7V Lithium-ion battery (4 to 5 days on a charge for typical usage) […]

Simblee Low Latency Bluetooth LE IoT Module Loads Its App to Your Smartphone on Demand

RF Digital launched RFDuino Bluetooth Low Energy board in 2013/2014, and the company has now developed Simblee module, whose name is derived from “Simple”  and “BLE”, and offers low latency (3ms) and integrates a user application that’s automatically and temporary loaded to your smartphone or tablet upon connection. The module is also part of an add-on board (RFD77201) for RFDuino board. Simblee RFD77101 module specifications: MCU – ARM Cortex M0 micr-controller (Nordic nRF51822???) Memory/Storage – 24KB RAM and 128KB flash for user application Bluetooth Smart / LE Bluetooth Low Energy (BLE) Stack Simblee interference immunity 3ms latency (for connection); 10us accuracy (jitter) -93dBm receiver sensitivity -55dBm to +4dBm TX power Physical range adjustable from a few inches to hundreds of feet Integrated antenna, integrated shield I/Os 29 GPIOs (flexible pin configuration) 6x ADC inputs 4x PWM outputs 2x SPI master/slave, 2x I2C, 1 x UART Security – Built in AES […]

BBC Micro Bit Educational Board Features nRF51822 ARM Cortex M0 MCU

The BBC announces its intention to give away 1 million Micro Bit to British schoolchildren a few months ago, but at the time, the specifications were not completely frozen. The broadcaster has now finalized the design which is based on an ARM Cortex M0 micro-controller.   Micro Bit board specifications: ARM Cortex M0 micro-controller (Nordic Micro nRF51822 Bluetooth SoC) 5x holes for 3V, GND, and 3 GPIOs 2x user buttons, 1x reset button 25x red LED indicator lights in a 5×5 matrix Connectivity – Bluetooth LE Sensors – Compass, magnetometer, accelerometer USB – 1x micro USB port for port and programming Power – 5V via USB or battery port to connect two AAA batteries Dimensions – 4cm x 5cm On the software side, the BBC has partnered with Microsoft to develop a web based, drag and drop interface for programming called TouchDevelop. Samsung is also involved in the project as […]

XBAND is a Tiny $10 Bluetooth Low Energy Sensor Module (Crowdfunding)

ZX Tek‘s XBAND is a board about half the size of a micro SD that comes with a Bluetooth LE radio and a 6-axis MPU6500 motion sensor that can be integrated into wearables and IoT applications such as a remote controlled robot with a camera., a wireless smart light-bulb, and iBeacon device and so on. There seems to be two versions of the module XBAND 061-N51822 and XBAND 1018-CY8C4247 with the following specifications: SoC (one or the other) Nordic Semiconductor nRF51822 ARM Cortex M0 MCU @ 16 MHz with 256KB Flash, 16KB RAM, and Bluetooth Low Energy support Cypress PSoC4 BLE core ARM Cortex M0 MCU @ 48 MHz with 128KB flash, 16KB RAM, and Bleutooth Low Energy support Bluetooth – 4.0/4.1 with high gain ceramic chip antenna Sensors – On-board 6-axis MPU6500 motion sensor + an extra configurable sensor (not idea what that is…). Connectors – Board-to-board connectors with […]
