Numato Spartan6 CSG225 PCB giveaway

Numato is giving away Spartan6 CSG225 bare boards. This FPGA development board features the Spartan6 FPGA in the CSG225 BGA package, a PIC32 microcontroller, and SDRAM. The FPGA to SDRAM traces are length matched, ensuring proper SDRAM timing. While researching potential applications for this board, I came across information about 토토사이트. This reminded me of […]

SquareWear open source controller board

Ray reports he’s just finished working on a new open source wearable electronics controller board called SquareWear. It’s small (1.6″x1.6″) and has built-in USB port (used for programming the microcontroller, USB serial communication, and charging battery). It also has 4 on-board MOSFETs for switching high-current load (up to 500mA). The board is based on Microchip’s […]

Stellaris Launchpad hack adds LiPo capability

Philipp Stenkamp wanted to power his Stellaris Launchpad with a spare LiPo battery, but found as shipped this wasn’t a plug-and-play operation. “The Launchpad expects 4.75-5.25 VDC on VBUS, nothing that a single cell LiPo could provide. I know that the system voltage is 3.3 VDC and that the voltage regulator on the board has […]

Eridani Cortex M3 development board is on sale

Brian decided to close shop on the Cotex M3 development boards. His brainchild, the Eridani, is based on TI’s Stellaris LM3S3651 and features USB OTG functionality. He has stopped sales, and would like to sell off or trade leftover boards that need some rework. I have a hand full of Eridani’s that need rework. I […]

freeSoC PSoC dev board

The freeSoC is a Programmable System on Chip (PSoC) based development board currently being developed by Jon Moeller, a student at Texas A & M University. Freesoc uses the PSoC5 chip from Cypress Semiconductors, which is supported by their free, full-featured PSoC Creator IDE. These programmable logic devices are really amazing and are definitely worth […]

I2C multiplexer shield controls 8 independent I2C buses

Sometimes I2C addresses can over lap, or maybe you need to use more than one of the same device. The I2C multiplexer shield is a way to control 8 I2C buses from a single I2C peripheral on a microcontroller. Voltage translation is also handled by the multiplexer chip. It was built on an Arduino shield […]

ARM board comparison chart

Avishay had been looking at several different ARM boards and wanted to find a comprehensive list of inexpensive boards. After viewing several lists which didn’t provide what he was looking for, he assembled this list of his own. It’s in tabular form, making it easy to compare board characteristics, and covers boards based on an […]

Driving an LCD from a broken laptop with an FPGA via the Papilio Plus board

Alex connected up an salvaged laptop LCD to his Papilio Plus FPGA development board. He is designing a pair of boards for easier interface, one is designed as a wing for the dev board, and the other as a breakout for the LCD. They’ll be connected together via an HDMI cable, even though the protocol […]

Review of the Stellaris LaunchPad

Alex wrote a review of the Stellaris LaunchPad. This is Texas Instrument’s latest development board in the LaunchPad series. It is built around the Cortex M4 microcontrollers. All in all, AWESOME little boards for $5! Especially considering that, once they’re available wholesale, the bare chip goes for $4.40@1kU, and there are two on the board! […]

Freescale debuts Kinetis L Series Freedom development platform

Freescale has inroduced their Freedom development board. The FRDM-KL25Z platform is enabled by Kinetis L Series KL1 and KL2 MCUs families built on ARM Cortex-M0+ processor. The board includes the MKL25Z128VLK4 MCU running at 48 MHz with 128 KB flash, 16 KB SRAM, USB OTG (FS), capacitive touch “slider,” MMA8451Q accelerometer and tri-color LED. The […]

PIC-based game development platforms

FUN BitPack is designed for developing games on Orbit16 PIC24 and PIC32 development boards. It has a Nokia 3310 display, a Joystick, two buttons, and a buzzer: FUN BitPack is suitable for making hand-held videogames such as our “ORbitSnake”, a Snake game version for ORbit16 (see Below). To enter the bootloader with FUN BitPack attached, […]

Energy Micro EFM32 design contest

Energy Micro is conducting a design contest based on their EFM32 product line. The contest is looking for great low power design ideas based on an EFM32 and is open for entries until October 31, 2012. From those entries an Energy Micro jury will then select up to 40 submissions that will receive a free […]

LatticeSemi offers discounted FPGA dev boards

Lattice Semi is offering the iCEblink40 Evaluation Kits for $19 for a limited time. The iCEblink40 boards feature the ultra low density iCE40 FPGA and come in two versions, the iCEblink40-HX1K and the iCEblink40-LP1K Evaluation Kits which differ in the number of I/O pins. Both boards offer 1280 logic look up tables and 64K bits […]

Little Wire Python library

Adam ported Little Wire’s library to Python. The library was already available in C, C++, and Processing, and now Python users can enjoy the little hack tool as well. Little Wire is multi-featured USB controlled open source hardware tool packed in a minimal form factor designed by Ihsan Kehribar. Even though it has minimal form […]

A look at the Teensy 3.0 testbed of nails

SJaak refers us to this article by Paul Stoffregen about how they test new Teensy 3.0 boards using a “testbed of nails.” Essentially the Teensy 3.0 crew has developed this testing interface which gives them a way to test every new board by bringing it into contact with the test jig’s pins. The result is […]

Cubieboard: Another Linux computer on a board
