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 […]

Suptronics X200 Raspberry Pi Model B+ Expansion Board Adds Wi-Fi, RTC, VGA, optical S/PDIF, USB ports, Servo Support, and More
The Raspberry Pi is a nice little board, but in some cases you may want to add some extra ports. Suptronics released the X100 expansion board for Raspberry Pi Model B last year, and they’ve now come up with a little monster called X200 expansion board for Raspberry Pi Model B+ which adds Wi-Fi, a real-time clock + battery, a VGA port, optical S/PDIF output, 3.5 mm mic and audio jack, servo support (ULN2803), and a few USB ports to the low cost board. Key features of X200 expansion board: Input Voltage – 6V to 21Vdc converted to 5V, 3A via step-down DC/DC converter to power the Raspberry Pi. VGA output – HDMI to VGA converter supporting up to UXGA (1600×1200) and 1080p with 10-bit DAC Audio – 3.5mm MIC in jack, 3.5mm stereo audio jack, S/PDIF output, audio I/O connector (Microphone input and stereo audio amplifier 3.3Wx2) Connectivity – […]
Robotics News – Hack-E-Bot and RiQ Educational Robots, and Maker Club 3D Printed Robots (Pre-Orders / Crowfunding)
I’ve come across several robotic projects this week, so instead of picking one up, or writing a post for each, I’ll summarize the three products into one post. Two of the projects are educational robots based on Arduino, with the sub $50 Hack-E-Bot, or the more advanced RiQ robot, and Maker Club is a company providing the electronics for robotics kit, and you print the plastic parts with your 3D printer. Hack-E-Bot Robot Hack-E-Bot is an affordable open source robot that hopes to encourage children to learn about engineering, electronics, and programming. The robot is powered by Adafruit’s Trinklet Arduino compatible board, connected to a breadboard, and some add-on boards sensors. The basic version comes with a Sonar sensor, but more add-on boards are on the way including bump sensors, a buzzer, colored lights, a claw, a servo scanner, and so on. The project is listed on CrowdSupply, and has […]
Microchip Unveils chipKIT Wi-Fi Development Board and Motor Control Shield

Embedded Artists NXP LPCXpresso Motor Control Kit Promotion
Embedded Artist and NXP have jointly designed the LPCXpresso Motor Control Kit to easily get started with motor control prototyping. This platform is based on NXP LPCXpresso MCUs and can control BLDC (Brushless DC), BLAC (Brushless AC), stepper and dual brushed DC motors. This is not a new design (2010), but Embedded Artist and NXP are discounting their development kit by 50% for a limited period, which brings the price of the kit to 149 Euros, instead of 299 Euros. The kit includes: LPCXpresso Motor Control Board LPCXpresso LPC1114 Board (The “stick” on the left in the picture above) LPCXpresso Eclipse-based IDE and GNU compiler BLDC Motor with hall sensors 24V Power supply (60W) Here are the specifications of the Motor Control Board: Controller MCU • Socket for LPCXpresso LPC1114 and LPC1343 • Socket for LPCXpresso LPC176x • Socket for LPC1xxx in PLCC44 • Expansion connector for control by LPC1800/LPC4000/LPC2900 […]
