EasyVolts USB Dongle Outputs 0-24V DC, Exposes UART, GPIO/PWM, RS-485 Signals

A while ago, I wrote about USBminiPower, a USB power supply with 3.3V, 5V, and one variable DC output up to 14.3V adjustable with a rocker switch, and equipped for a 4-digit LED display showing current intensity and voltage. But recently, I was made aware of another USB power supply – EasyVolts USB dongle – that supports 0 to 24V DC, and also exposes either UART pins, or RS-485 signal, plus two GPIO/PWM pins. EasyVolts specifications: USB – 1x USB port for power, communication Power Supply function: Input voltage: 5V from USB port Output voltage: 0-24V Max output current: 1A Max output power: ~2.4W (e.g. 24V/0.1A; 3.3V/0.55A) Voltage resolution: <50mV Current resolution: <2mA I/O expansion 4- pin to be used as UART (Tx/Rx) or RS-485 + 2x GPIO/PWM UART – speed: 300-230400 bit/sec; resistance of Tx/Rx pins: 300 Ohm PWM – Base frequency: 240kHz.; frequency division configuration: 1-65535; duty cycle […]

Think Silicon Ultra Low Power NEMA GPUs are Designed for Wearables and IoT Applications

When you have to purchase a wearable device, let’s say a smartwatch or fitness tracker, you have to make trade offs between user interface and battery life. For example, a fitness tracker such as Xiaomi Mi Band 2 will last about 2 weeks per charge with a limited display, while Android smartwatches with a much better interface need to be recharged every 1 or 2 days. Think Silicon aims to improve battery life of the devices with nicer user interfaces thanks to their ultra-low power NEMA 2D, 3D, and GP GPU that can be integrated into SoCs with ARM Cortex-M and Cortex-A cores. The company has three family of GPUs: NEMA|p pico 2D GPU with one core 4bpp framebuffer, 6bpp texture with/out alpha Fill Rate – 1pixel/cycle Silicon Area – 0.07 mm2 with 28nm process Power Consumption – leakage power GPU consumption of 0.06mW; with compression (TSFSc): 0.03 mW NEMA|t […]

Getting Started with MPLAB Xpress Board and Online IDE

Microchip launched MPLAB Xpress online IDE and board earlier this year, and as part of the launch they offered 2,000 free boards. I joined the program and received my board. The keyword for the board is “Xpress”, as you should be able to get started in mere minutes thanks to the operating system agnostic online IDE that works with Internet Explorer, Firefox, Chrome, and Safari. That also means you don’t need to install any other tool. All you need is a web browser. MPLAB Xpress Board Let’s start by quickly checking out the package, board, and offline documentation. Once you open the package, you’ll get the board, a folded sheet of paper for the schematics, and some information on the package itself with the pinout diagram, and a quick start guide explaining that the board acts as a mass storage device, and all you need is a web browser for […]

$15 Microchip Curiosity Development Board Supports 8-bit PIC Microcontrollers

I’ve just found out Microchip had introduced Curiosity development board a little while ago, in order to let students and others experiment with their 8-bit PIC DIP MCUs, and including MikroElectronika Mikrobus footprint, an interface for Microchip RN4020 module to add Bluetooth Low Energy, as well as other headers and some extra features like buttons, and a potentiometer. Microchip Curiosity board specifications: MCU – PIC MCU socket for 8, 14, and 20-pin micro-controllers with PIC16F1619 pre-installed. Expansion mikroBUS Click Board footprint Microchip RN4020 Bluetooth Module Footprint USB – USB mini-B connector Misc – Master Clear Reset button, potentiometer, LEDs, mTouch button, push button Power Supply 5V via USB 9V using an external power supply (footprints only) 3.3V to 5V external power supply via TP3 and TP4 pins Dimensions – N/A There are over 160 MikroElektronika Click boars on the market now, but only seven are listed with code samples for […]

Microchip Introduces $11 RN2483 & RN2903 LoRa Modules and $70 LoRa Evaluation Kits for IoT & M2M Applications

LoRa is one of those long range low power WAN standards used for the machine to machine (M2M) and Internet of things (IoT) applications. I already featured a Semtech Lora module here with a line-of-sight range of up to 20 to 30km, and the company has just partnered with STMicro to deploy LoRa solutions, but today, I’m going to have a look at Microchip Lora modules and development kits that I discovered in the company’s Micro Solutions Nov/Dec 2015 publication. The company has launched two modules for the European and North American markets with respectively RN2483 LoRa 433/868 MHz R&TTE Directive Assessed Radio Modem and RN2903 915 MHz North American modem. Apart from the different frequencies, both modules have similar features: On-board LoRaWAN Class A protocol stack Tx/Rx Power RN2483 – 40 mA (14dBm, 868MHz) Tx, and 14.2 mA Rx @ 3.6V RN2903 – 124 mA Tx max, and 13.5 mA […]

USBminiPower USB Power Supply Delivers 3 Outputs: 5V, 3.3V, and a Variable Output up to 14.3V (Crowdfunding)

Yesterday, I found out about a cheap 5V/3.3V USB power supply board, YwRobot MB-102, selling for $1 shipped on Ebay, but one person lamented the lack of 1.8V output, which may be required for example for modules like AsiaRF AWM002 that takes both 3.3V and 1.8V. One way is make your own power board, and get an expensive lab power supply, but I got a solution in my inbox this morning, with USBminiPower, as tiny USB power supply board with three output: 5V, 3.3V and a variable pin between 1V and 14.3V, as well as a 4 digit LED display showing the voltage and intensity just like Charger Doctor. USBminiPower specifications: MCU – Microchip PIC16 MCU (several are supported) Voltage outputs – 5V (from USB port), controllable 3.3V, and controllable & adjustable 1V … 14.3V Display – 4 Digit red LED to display intensity and voltage Max Power – 2.45 […]

GroBotz Interactive Robot Project is Made of Easy to Assemble Smart Blocks (Crowdfunding)

GroBotz makes me think of Lego applied to robotics. The project consists of modules such as motors, sensors, buttons, switches, or cameras that snap together in order to create a robot on wheels, games, toys, a musical instrument, or whatever idea you may have, and the hardware is then programmed using a graphical user interface. A Raspberry Pi board is used for the brain of the robot, and Microchip PIC MCUs for the smart blocks. The software is programmed in C# using Xamarin, the user interface is based on Unity, OpenCV is used for image processing, and during development a plastic part where printed with Makerbot, and schematics and PCB layout designed with CadSoft EAGLE. The company has now come up with a number of modules as shown in the picture below. Your robot can then be controlled over Wi-Fi with GroBotz app which works on Windows, Mac OS, iOs, […]
