ZeroPi is an Arduino & Raspberry Pi Compatible Motor Control Board (Crowdfunding)

Pi boards keep on coming… As soon as I finished writing about Roseapple Pi board, yet another one popped out on my twitter feed… But that one is of a different kind, as it won’t run Linux, but instead the board is powered by an Atmel SAMD21 Cortex M0+ micro-controller, and can support lots of electric motors including up to 11 micro servos and 8 DC motors – or 4 stepper motors – simultaneously. ZeroPi board specifications: MCU – Atmel SAMD21J18 ARM Cortex M0+ @ 48 MHz with 32 SRAM and 256KB flash I/O pins via 33-pin header, 4-pin temperature sensor, and 10-pin Raspberry Pi header 35 GPIOs 4x 12-bit ADC channels 1x 10-bit DAC 2x UART 2-channel temperature sensor interface DC current per I/O pin- 7mA DC / Stepper Motor control – 4x 4-channel SLOT interface compatible with common parts such as DRV8825 or A4988 Stepper motor driver and […]

$35 Tessel 2 IoT Board Features Atmel SAMD21 MCU and Mediatek MT7620n WiSoC

Tessel is a Wi-Fi IoT board based on NXP LPC1830 Cortex M3 MCU and Texas Instruments CC3000 modules, that’s designed to bring embedded development to web programmers with a system that can be programmed with JavaScript and Node.js.  At the time of the crowdfunding campaign in 2013, the board was available with external modules (Relays, sensors, Bluetooth LE…) for $100 and up, but now Technical Machine, the company behind the project, has announced Tessel 2 combining Atmel SAMD21 Cortex M0+ to control I/O and Mediatek MT7260n for Wi-Fi connectivity, still programmable with JavaScript ot Node.js. Tessel 2 specifications: MCU – Atmel SAMD21G14A-MU Cortex M0+ MCU @ 48MHz with 16KB SRAM and 2KB Flash SoC – Mediatek MT7260n MIPS24KEc Wi-Fi SoC @ 580 MHz System Memory – 64MB DDR2 Storage – 32MB flash for firmware (OpenWRT) Connectivity – 10/100M Ethernet, and Wi-Fi 802.11 b/g/n with dual PCB antennas USB – 2x […]

DonglePi is a USB Dongle with a Raspberry Pi Header for your PC

While the newer Raspberry Pi A+, B+ and B2 boards feature the new 40-pin connector, the Raspberry Pi boards Model A and B have a 26-pin expansion header, but both are use to access GPIOs, UART, SPI, I2C and interface with external hardware, and many add-ons boards have been developed for the Raspberry Pi. But what if you’d like to use R-Pi add-ons board on your PC, or instead you are developing your own add-on board, but would like to do so directly on your PC for convenience? DonglePi is the answer. It’s a small USB dongle with Atmel SAMD21 MCU and a 26-pin Raspberry Pi compatible header, that you could use connect to your Android/Linux/Windows PC to play with GPIO, I2C, SPI, Serial, PWM just like on a Raspberry Pi, and using RPi/GPIO or smbus Python libraries for programming. The project is still in development, and so far most […]

ARM Cortex M0+ Based Arduino Zero Pro Board Gets Listed on Arduino.org

A new “Arduino Zero Pro” board has been listed on Arduino.org, which looks very similar to the Arduino Zero board announced last year, with Atmel ATSAMD21G18 ARM Cortex M0+ MCU, and that is still listed as “Coming Soon” on Arduino.cc website. So it feels a little odd Arduino would release a board with basically the same features. Arduino Zero Pro key specifications are indeed exactly the same: Microcontroller – Atmel ATSAMD21G18 32-bit ARM Cortex M0+ MCU @ 48 MHz with 32 KB SRAM, 256 KB flash, up to 16KB EEPROM (By emulation). 48-pin LQFP package. Digital I/O Pins – 14, with 12 PWM and UART Analog Input Pins – 6, including 5 12bits ADC channels and one 10 bits DAC DC Current per I/O Pin – 7 mA USB – 2x micro USB ports Debugging – USB via Atmel’s Embedded Debugger (EDBG) on-board debugger, and JTAG Misc – reset button, […]

Arduino Unveils Arduino Zero Board Featuring Atmel SAMD21 Cortex M0+ MCU

Arduino and Atmel have jointly announced the latest addition to the Arduino family with Arduino Zero, a development board based on Atmel SAMD21 ARM Cortex M0+ MCU with the same form factor and headers as Arduino UNO / Leonardo. Arduino Zero specifications: Microcontroller – Atmel ATSAMD21G18 32-bit ARM Cortex M0+ MCU @ 48 MHz with 32 KB SRAM, 256 KB flash, up to 16KB EEPROM (By emulation). 48-pin LQFP package. Digital I/O Pins – 14, with 12 PWM and UART Analog Input Pins – 6, including 5 12bits ADC channels and one 10 bits DAC DC Current per I/O Pin – 7 mA USB – 2x micro USB ports Debugging – USB via Atmel’s Embedded Debugger (EDBG) on-board debugger, and JTAG Misc – reset button, 5 LEDs (Tx, Rx, L, On, Debug) Operating Voltage – 3.3V That’s about all we know for now, as tools support (Arduino IDE?), availability and […]

Atmel Adds SAM D21, D10 and D11 MCUs to Its ARM Cortex M0+ SAM D Family

Atmel launched SAM D20 MCU family based on ARM Cortex M0+ last year, and at Embedded World 2014, the company has launched three new MCU families featuring ARM ultra low power core with SAM D10, SAM D11, and SAM D21 families and their corresponding Xplained PRO development boards. Atmel four SAM D  families target different applications and price points: SAM D10 – The smallest member of the SAM D family in terms of memory, pin count, and features. SAM D11 – Adds full-speed USB not available on the SAM D10. SAM D20 – “Offers a rich set of peripherals, flexibility, and ease-of-use with low power consumption.” SAM D21 – Adds features such as full-speed USB, DMA, high-end timers/counters to D20 design. I’ve compared the four families in the table below: SAM D10 SAM D11 SAM D20 SAM D21 # MCU in Family 4 4 15 12 MCU Core ARM Cortex-M0+ […]

Atmel Introduces ARM Cortex M0+ based SmartConnect Wi-Fi Modules and SmartConnect Zigbee SoCs

In order for the Internet of Things to take off, wireless connectivity solutions with ultra low power, lost cost, and small footprint are needed. Atmel seems to have made a step in the right direction by launching SmartConnect Wi-Fi modules and Zigbee SoCs featuring an ARM Cortex M0+ core. SmartConnect Wi-Fi does not appear to be a single chip solution, but instead Atmel has created a family of Wi-Fi modules integrating the company’s ultra-low power Wi-Fi SoChip with an ARM Cortex M0+ based MCU. These modules will enabled battery-powered Wi-Fi connectivity for IoT endpoints such as thermostats, and temperature sensors in a cost effective way. The company will provide a software solution with application and security protocols such as TLS, TCP/IP stack and an RTOS, all of which can be downloaded via Atmel Studio 6 Integrated Development Platform (IDP). SmartConnect ZigBee SAM R21 combines an ARM Cortex M0+ core with […]
