USBCEE Tiny-PAT Board Helps Testing USB-C Power Adapters (Crowdfunding)

September 13th, 2017 No comments

USB power delivery allows for up to 100W charging using 20V @ 5A through a USB type C port, and the specifications also mandate supports for various voltages between 5V and 20V. However, some USB-C power adapter that not be fully compliant with the specifications, potentially risking to damage your device. USBCEE Tiny-PAT board has been created in order to test such power adapters to make sure they are compliant with USB PD 2.0/3.0 specifications.

Tiny-PAT board features and specifications:

  • Supported USB Spec Version – PD 2.0 / PD 3.0
  • Max Voltage: 24 V
  • Max Current: 5 A
  • Max Power: 100 W
  • USB type C receptacle
  • Misc – Fail and Pass LEDS, S4 mode button, through holes for VBUS & GND
  • Power Consumption: ~10 mA (may vary based on voltage)
  • Dimensions – 35 x 20 mm

By default, the board will test all power rules advertised by the power adapter, measure the voltage (VBUS), and show whether the test failed or passed with the LEDs on the board.

USB PD 3.0 Power Ratings, Voltages and Currents – Source: Texas Instruments

S4 button is used to switch to manual mode, where you can switch between each power rule, and verify the voltage(s) with a multimeter, external load, or oscilloscope. In that mode, Tiny-PAT could also be used a variable power supply where you can for example, select 5 V/3 A, 9 V/3 A, 15 V/3 A or 20 V/4.35 A  with Apple’s 87 W USB-C power adapter, or 5 V/3 A, 7 V/3 A, 8 V/3 A, 9 V/2.7 A, or 12 V/2 A with Verizon USB charger. The company promises to release schematics under an open license.

USBCEE has launched a CrowdSupply campaign to raise some funds for mass production of the board. A pledge of $40 should get you a Tiny-PAT board shipped at the end of November. Shipping is free to the US, and adds $7 to the rest of the world.

Husarion CORE2 STM32 Board for Robotics Projects Works with ESP32, Raspberry Pi 3, or ASUS Tinkerboard

June 30th, 2017 No comments

Husarion CORE2 is a board designed to make robotics projects simpler and faster to complete with pre-configured software and online management. Projects can start using LEGOs, before moving to 3D printed or laser-cut version of the mechanical parts without having to spend too much time on the electronics and software part of the project.

CORE2 and CORE2-ROS Boards – Click to Enlarge

Two versions of the board are available: CORE2 combining STM32 MCU with ESP32 WiFI & Bluetooth module, and CORE2-ROS with STM32 instead coupled to a Raspberry Pi 3 or ASUS Tinkerboard running ROS (Robot Operating System). Both solutions share most of the same specifications:

  • MCU -STMicro STM32F4 ARM CORTEX-M4 MCU @ 168 MHz with 192 kB RAM, 1 MB Flash
  • External Storage – 1x micro SD slot
  • USB – 1x USB 2.0 host port with 1A charging capability; 1x micro USB port for debugging and programming via FTDI chip
  • Expansion Headers
    • hRPi expansion header for
      • CORE2-ROS –  a single board computer Raspberry Pi 3 or ASUS Tinker Board
      • CORE2 – an ESP32 based Wi-Fi module
    • 2x motor headers (hMot) with
      • 4x DC motor outputs with built-in H-bridges
      • 4x quadrature encoder inputs 1 A cont./ 2 A max. current per output (2 A/4 A current when paralleled)
    • 6x servo ports with selectable supply voltage (5 / 6 / 7.4 / 8.6 V) 3 A cont./4.5 A max. current for all servos together
    • 6x 6-pin hSens sensor ports with GPIOs, ADC/ext. interrupt, I2C/UART, 5 V out

  • Misc – 5x LEDs, 2x buttons
  • Power Supply – 6 to 16V DC with built-in overcurrent, overvoltage, and reverse polarity protection
  • Dimensions – 94 x 85 mm

On the software side, Husarion provide a set of open source libraries for robots as part of their hFramework, using DMA channels and interrupts internally to handle communication interfaces. The company has also prepared tutorials dealing with ROS introduction, creating nodes, simple kinematics for mobile robot, visual object recognition, running ROS on multiple machines, and SLAM navigation. CORE2 board can also be programming using the Arduino IDE, and finally Husarion Cloud allows you to securely create a web user interface to control the robot, and even program the robot firmware from a web browser.

That means you can program your robot using either the Web IDE, or offline with an SDK plus Visual Studio Code and the Husarion extension. The development work flow is summarized above.

CORE2 boards can be used for a variety of projects such as robotic arms, telepresense robots, 3D printers, education robots, drones, exoskeletons, and so on. If you want to learn about robots, but don’t have LEGO Mindstorms and don’t feel comfortable making your own mechanical parts yet, ROSbot might be a good way to start with CORE2-ROS board, LiDAR, a camera, four DC motors with encoders, an orientation sensor (MPU9250), four distance sensors, a Li-Ion battery (3 x 18650 batteries) and a charger, as well as aluminum mechanics. It also happens to be the platform they use for their tutorials.

ROSbot

You’ll find all those items, and some extra add-on boards, on the CrowdSupply campaign, starting at $89 for CORE2 board with ESP32 module, $99 for CORE2-ROS board without SBC, and going up to $1,290 for the complete ROSbot with ASUS Tinker Board. Shipping is free to the US, and $8 to $20 depending on the selected rewards, with delivery scheduled for September 2017, except for ROSbot that’s planned for mid-October 2017.

June 29th, 2017 8 comments

OLIMEXINO-85S may have held the title of the world’s smallest Arduino (compatible) board for the last few years, being barely bigger than a micro SD card as it measures about 16.9 x 12.7 mm, but there’s a new mini champion in town with μduino board measuring just 12 x 12 mm.

μduino prototype

μduino board specifications:

  • MCU – Microchip Atmel ATMEGA32U4 8-bit AVR microcontroller @ 16 MHz with 2,560 bytes of RAM, 32KB flash, and 1024 bytes of EEPROM (Arduino Leonardo compatible)
  • I/Os
    • 6x Analog I/O ports
    • 14x Digital I/O ports (including Rx/Tx) including  7x PWM
    • 1x Analog reference voltage port
    • 1.27mm pitch
  • Programming / Debugging – 1x micro USB port; 6-pin ICSP programming ports (load custom bootloaders, program other boards, etc)
  • Misc – Status LED, reset button
  • Power Supply – 5V via micro USB port; 5V voltage regulator (accepts up to 16V DC);  2x 5V ports;  2x ground ports
  • Dimensions – 12x 12 mm with 2 mounting holes (prototype is 14×14 mm)

Sizes Comparison: Arduino UNO vs Arduino Nano vs μduino

The µduino board is said to be particularly suited for projects such as a mini quad-copter, a GPS logging module, small multimeters, heart rate monitors, and other wearables. The project has launched on Crowdsupply with a $5,000 US funding goal. While µduino may be the smallest Arduino board, it’s not quite the cheapest, as you’d need to pledge $18 to get the board with a micro USB cable. Shipping is free to the US, and $7 to the rest of the world, with delivery scheduled for the end of September 2017.

Finally, the company has also designed Hornbill ESP32 Proto board where you can solder ESP32 Dev board, and add whatever components you may need for your project. The Proto board also includes a microSD card slot, an RGB LED, an SHT 31 humidity and temperature sensor, as well as footprints for 6x IR transmitters and 1x IR Receiver.

Hornbill Weather Proof Case and Kits

Beside the boards, the developers also provide an IP67 case for it, as well as kits leveraging the case:

  • Hornbill OUR (Open Remote Control) – Bluetooth (BLE) to Infrared (IR) bridge to control IR devices with your smartphone
  • Hornbill Lights – Control RGB LED strips over Bluetooth Smart
  • Hornbill IDL (Industrial Data Logger) – Logs power and temperature values, and upload them securely to the cloud.

There’s also Hornbill Makers Kit without the case, but with Hornbill ESP32 Dev and plenty of modules to play with, such as relays, various sensors, LEDs, a buzzer, an OLED display, a mini breadboard and so on… You’ll find ESP32 firmware and Android app source code for all kits on ExploreEmbedded github account.

 

Hornbill project has just launched on CrowdSupply with the goal of raising at least $2,000. A $12 pledge is asked for Hornbill ESP32 Dev or Hornbill Minima, $15 for the case, and the kits go from $39 (Hornbill ESP32 Dev + Proto board + Case) to $79 for Hornbill Lights with a WS2812 LED strip. Worldwide shipping is included in the price, and delivery is scheduled for June 2017. Noe that this is not the first project from ExploreEmbedded, as they previously launched Explorer M3 board based on NXP LPC microcontroller. However, since CrowdSupply do not show backers’ comments, I could not check whether backers are happy, or the project shipped on time.

MacroFAB FX Development Board is an Open source Audio Electronics Prototyping Platform (Crowdfunding)

A couple of years ago, I wrote about a Linux multi-effects guitar pedal, and if you are interested in such audio projects, another company called MacroFab, specializing in manufacturing & assembling PCBs & electronic device, has now designed open source FX development board for audio electronics prototyping, that can be used for audio effects “guitar” pedals, and let you design your own tones.

Key features of FX development board:

  1. Potentiometers
  2. 9V battery holder
  3. ¼” Input and output jacks connected to breadboard
  4. True bypass 3PDT switch
  5. User selectable power supply connections
  6. Dual solderless breadboards with power rails selectable by jumpers
  7. Adjustable 9 V power supply
  8. Power supply with 2.1 mm dc input jack for use with AC-to-AC wall wart; +/- 15 volt @ 200 mA power supplies with over-current protection; +1.25 to 9 V @ 150 mA adjustable power supply; Split voltage rail (1/2*9 Volt Rail) @ 15 mA for use as a virtual ground

The board can be used for audio applications by guitar FX designers, electronic audio hobbyists, and music creators, but also for any kind of electronics projects. The company will provide pedal templates and schematics available for download on fxdevboard.com site. The company also encourages makers to design their own PCB after prototyping, and send them the gerber files for manufacturing.

FX Devboard project has now launched on CrowdSupply where the company aims to raise at least $25,000. A $150 pledge should get you the board with a power adapter, but if you want a case and a wire jumper kit, you’ll need to pledge $190. Delivery is planned for April 14, 2017, and while shipping is free to the US, it adds $20 to the rest of the world.

SonikTech e-Paper Shield Starter Kit Relies on Teensy LC MCU Board

December 23rd, 2016 2 comments

Soniktek Electronics has designed the “e-Paper Shield Starter Kit” featuring Pervasive Displays’ E2215CS062 e-paper screen, and an adapter board to connect it to Teensy LC (Low Cost) board powered by NXP Kinetis L ARM Cortex M0+ microcontroller @ 48 MHz, or other 3.3V MCU boards supporting SPI.

e-paper-devkitAdapter board & display specifications:

  • Supports Pervasive Displays 2.15″ E2215CS062 e-paper screen with 208 x 112 resolution, no backlight required, fully sunlight-readable
  • Communication protocol – SPI  @ 3.3V
  • Sensor – On-board thermometer with I2C interface
  • Dimensions – Screen: 48 mm x 26 mm; adapter board fits into Teensy-LC module (36x18mm)

The advantages of e-Paper display are that they don’t require power to maintain an image, and they can be read in sunlight, just like actual paper. I can’t remember having seen many – if any – low cost e-Paper development kits so far, and the project is open source hardware with design files and source code available on hackster.io.

The project was successfully funded on Crowdsupply last month, but you can now pre-order directly on the platform, starting at $25 for the adapter only if you already have an MCU board and the e-Paper display, $50 for the adapter board, and display, and $75 for a full kit with Teensy LC board, the adapter board, and the e-Paper Display. Shipping is free to the US, and $5 to the rest of the world.

If you are interested in e-Paper display development kits, I’ve noticed there are a dozen listed on Pervasive Display e-Ink development kits page, including e-Paper HATs boards for Raspberry Pi Zero, and other Raspberry Pi boards, and e-Paper shields for Arduino.

Winkel board can be programmed with the Arduino IDE via a micro USB cable, but you could also program the Atmel MCU over Bluetooth, and ESP12 module over WiFi without any cable required, a must if you want to update your firmware while the board is already in a case or hard to access. Thanks to the company’s “Smart Opt system” individual components can be power on and off individually, so that unused module don’t draw power. Source code for the firmware and code samples can be found on github.
