I’ve recently learned that the battle between the two Arduino teams, namely Arduino SRL (arduino.org) in Italy, and Arduino LLC (arduino.cc) in the US, had taken another turn with Arduino LLC now branding their boards as Arduino in the US, and Genuino in the rest of the world. This may certainly bring confusion to new comers, especially as they have to deal with different version of the Arduino IDE. With that backdrop, Arduino LLC has now introduced Arduino 101 (aka Genuino 101) board powered by Intel Curie module with Quark SE x86 SoC with Bluetooth LE and a 6-axis combo sensor. Arduino 101 specifications: SoC – Intel Curie compute module including an Intel Quark SE x86 32-bit microcontroller @ 32 MHz and an a DSP sensor hub @ 32Mhz with 384 KB flash, 80 KB SRAM (24KB available for sketches), , Bluetooth LE, and 6-axis combo sensor with accelerometer and […]
Walabot MIMO Radar Board Can See Through Walls Thanks to Vayyar 3D Imaging Sensors
A few days ago, I wrote about Orbbec Astra 3D camera that can analyze distance and depth to form a 3D image of object. However, this solution uses an IR sensors, and while it can fulfill the needs of many application it does not allow to see through object, and that’s exactly what Walabot wideband MIMO radar board promises to do thanks to Vayyar 3D imaging sensor and a dozen of RF antennas. Some of the key features and preliminary specifications of Walabot board include: Vayyar VYYR2401 3D imaging sensor 12 (or is it 14?) non-contact antennas array system based on “Octopus A3 System on chip” Build in Tx/Rx linear polarized wide-band antennas from 3-10Ghz. On-board Cypress FX3 controller for communication and pre-processing EEPROM (for inventory and calibration information) Walabot interface connectors: Micro-USB 2.0 for high-rate data communication. Option to provide supply from USB. Single supply voltage 4.5-5.5v input for […]
AMS AS7000 Biosensor is Designed for Strapless Optical Heart Rate Monitors
Heart rate monitors (HRM) with chest straps are now being replaced by more comfortable strapless HRM, such as UWatch UX. These products are enabled by photoelectric sensors that sample light modulated by blood vessels, which expand and contract as blood pulses through them. One of such solutions is the recently introduced AMS AS7000 including a Cortex M0 core, and a DSP implementing algorithm to process raw photoplethysmography (PPG) readings from the sensors to convert them into digital HRM and HRV (Heart Rate Variability) values. Highlights of AS7000 Biosensor: MCU – ARM Cortex M0 with 4KB RAM, 32 KB EEPROM I/Os – 9 GPIOs, UART, SPI, I2C Analog electrical and optical Frontends Hardware sequencer Synchronous detector Integrated LEd driver with current control Optical filters Supply Voltage – 2.6 – 3.6V Temperature Range –30 to 70°C Package – 18 pins AS7000 can deliver greater accuracy when it is paired with an external […]
Digilent ARTY is a $99 Xilinx Artix-7 FPGA Board with Arduino Headers
Low cost FPGA boards with Arduino headers are nothing new, as we’ve seen before with Arduissimo and Papilio DUO, but both of these boards are based on Spartan 6 FPGA, while the recent Digilent ARTY board is powered by an Artix-7 FPGA. Beside the hardware differences, Spartan 6 FPGAs only support Xilinx ISE Design Suite, while Artix-7 parts are also supported by Vivado Design Suite, which according to Xilinx has a much better workflow and user interface. Digilent ARTY specifications: FPGA – Xilinx XC7A35T-L1CSG324I with 33,280 logic cells, 1,800 Kb block RAM, 90 DSP slices, and 250 I/O pins System memory – 256 MB DDR3L SDRAM Storage – 16 MB of QSPI Flash Connectivity – 10/100M Ethernet Expansion interfaces 4 Digilent compatible Pmod interfaces enabling 32 user I/O pins: 2 Pmods routed as differential pairs, paired to fit dual-wide Pmods Arduino UNO R3 shield / chipKit interface Debugging – USB-UART Interface, […]
