HackaBLE Board is a Tiny, Breadboard-Friendly Bluetooth LE Development Board

Earlier this year, I wrote about Electronut Labs’ Bluey development board powered by Nordic Semi nRF52832 development board with BLE, NFC, and a few sensors, and partially open source hardware with the KiCAD schematics and PCB layout available on Github. The company is now back with another open source hardware nRF52832 BLE board, namely hackaBLE, that’s much smaller (28x18mm), and with 2.54mm pitch castellated pin headers making suitable for use for breadboard, or as a module on a custom designed board. hackaBLE board specifications: SoC – Nordic Semi nRF52832 ANT + BLE ARM Cortex-M4 @ 64 MHz processor with 512kB flash, 64kB RAM Connectivity – Bluetooth 4.2/5 LE and other proprietary 2.4 GHz wireless standards via chip antenna Expansion 2x 9-pin castellated headers with GPIO, 5V, 3.3V, and GND 2x 5-pin solder pads for more I/Os Debugging – 4-pin SWD header Misc – RGB LED, and user button Power Supply […]

LoFive is a Tiny Open Source Hardware Board based on SiFive FE310 RISC-V Open SoC

Do you remember HiFive1? It’s an Arduino compatible board based on the SiFive FE310 open source RISC-V SoC. Michael Welling has now started working on LoFive board using the same processor, but in a much smaller & breadboard friendly form factor. LoFive board specifications: MCU – SiFive Freedom E310 (FE310) 32-bit RV32IMAC processor @ up to 320+ MHz (1.61 DMIPS/MHz) Storage – 128-Mbit SPI flash (ISSI IS25LP128) Expansion – 2x 14-pin headers with JTAG, GPIO, PWM, SPI, UART, 5V, 3.3V and GND Misc – 1x reset button, 16 MHz crystal Power Supply – 5V via pin 1 on header; Operating Voltage: 3.3 V and 1.8 V Dimensions – 38 x 18 mm (estimated) The board will be programmable with Arduino IDE + Cinco just like HiFive1 board. The board is also open source hardware, so beside the aforelinked info on Hackster,io, you’ll also find the KiCAD schematics, PCB layout, and […]

Embedded Linux Conference & Open Source Summit Europe 2017 Schedule

The Embedded Linux Conference & IoT summit 2017 took place in the US earlier this year in February, but there will soon be a similar event with the Embedded Linux Conference *& Open Source Summit Europe 2017 to take up in Europe on October 23 – 25 in Prague, Czech Republic, and the Linux Foundation has just published the schedule. It’s always useful to find out what is being discussed during such events, even if you are not going to attend, so I went through the different sessions, and compose my own virtual schedule with some of the ones I find the most interesting. Monday, October 23 11:15 – 11:55 – An Introduction to SPI-NOR Subsystem – Vignesh Raghavendra, Texas Instruments India Modern day embedded systems have dedicated SPI controllers to support NOR flashes. They have many hardware level features to increase the ease and efficiency of accessing SPI NOR […]

PocketBone Board Based on Octavo Systems OSD3358 SiP Fits into an “Altoids Smalls” Mint Tin Box

Last year, Octavo Systems introduced OSD3358 System-in-Package (SiP) that includes Texas Instruments Sitara AM3358 processor, 256MB to 1GB RAM, a PMIC and an LDO into a single package. Since then the SiP has been found in BeagleBone Black Wireless and BeagleBone Blue, and at the time of launch there was also some development around PocketBone, a tiny open source hardware Smalls mint tin sized board based on OSD3358, which is smaller than a CHIP board, but a little bigger than NanoPi NEO board. There’s now been some progress with prototypes of the board manufactured with the following specifications: SiP (System-in-Package) – Octavo Systems OSD3358 with TI Sitara AM3358 ARM Cortex-A8 processor @ up to 1 GHz,  PowerVR SGX530 GPU, PMIC + LDO, and 512MB DDR3 Storage – micro SD slot USB – 2x micro USB port one for power, one OTG port Expansion – 10-pin header (unpopulated) with SPI, I2C, […]
