Spark IO started with Spark Core, a tiny Wi-Fi module, followed with Spark Photon is a cheaper, faster, and tinier Wi-Fi module, and now the company is launching Spark Electron to bring cellular connectivity to hobbyist projects at an affordable cost and small form factor. Spark Electron specifications: MCU – ST Micro STM32F205 ARM Cortex M3 microcontroller @ 120 MHz with 1MB Flash, 128K RAM Cellular Connectivity – U-Blox SARA U-series (3G) or G-series (2G) modem + NanoSIM card slot + u.FL connector for Antenna Headers – 36 pins with 28 GPIOs (D0-D13, A0-A13), plus TX/RX, 2 GNDs, VIN, VBAT, WKP, 3V3, RST USB – micro USB port for power and programming Misc – Setup and reset buttons, LED Dimensions – 5.08 cm x 2.03 cm x 0.76 cm (1.27 cm including headers) The board can be programmed with Wiring (Arduino’s programming language), C/C++, or ARM assembly. It’s longer than Spark […]
FOSDEM 2015 Schedule – January 31 – February 1 2015
FOSDEM (Free and Open Source Software Developers’ European Meeting) takes place every year during the first week-end of February. This year the developer-oriented event expects to bring over 5000 geeks to share ideas and collaborate on open source projects. Contrary to most other events, it’s free to attend, and you don’t even need to register, just show up. FOSDEM 2015 will take place on January 31- February 1 in Brussels. There will be 551 sessions divided into 5 keynotes, 40 lightning talks, 6 certification exams, and with the bulk being developer rooms and main tracks, divided into 7 main tracks this year: Languages, Performance, Time, Typesetting, Hardware, Security and Miscellaneous. I’m not going to attend, but it’s still interested to see what will be talked about, and I’ve concocted my own little virtual program out of the main tracks and developers’ rooms. There’s a few minutes overlap between some talks […]
Fernvale Open Source Hardware IoT Board Based on Mediatek MT6260 SoC with GSM Connectivity
Andrew Huang (Bunnie), an hardware engineer, known for hacking the original XBOX, and more recently for Novena open source laptop, has decided it could be interesting to reverse-engineer Mediatek MT6260 processor, as in China, it’s difficult to get documentation, SDK, and tools if you don’t commit to purchase X chips, where X is a rather large number. He and others also checked whether their work could be open sourced legally, and assert their “fair use” rights to reverse-engineer hardware and firmware. And so Fernvale project was born both as a technical challenge and to make a point. MT6260 is a $3 ARM7EJ-S processor clocked at 364 MHz with 8MB built-in RAM, interfaces such as I2C, SPI, PWM, UART, as well as LCD and touchscheen controller, and audio codec, battery charger, USB, Bluetooth, and GSM support, which make the $6 Atmel MCU used in Arduino board look expensive. The main differences […]
