Caped Beagle is FPGA Superhero

We miss the days when everything had daughterboards. Now, Arduinos have shields and Raspberry Pis have hats. The BeagleBone has capes. Whatever. However, regardless of the name, the open source BeagleWire cape/shield/hat/daughterboard connects to a BeagleBone and provides a Lattice iCE40HX FPGA, some support hardware, and common I/O connectors like Pmod and Grove. You can see a video about the board below.

In addition to the FPGA, the board contains a EEPROM, RAM, flash memory, an oscillator, and a few buttons, switches and LEDs. The buttons even feature hardware debouncing. The parts list and design files are all available and …read more

TinyFPGA is a Tiny FPGA Board

We recently noticed an open source design for TinyFPGA A-Series boards from [Luke Valenty]. The tiny boards measure 18 mm by 30.5 mm and are breadboard friendly. You can choose a board that holds a Lattice Mach XO2-256 or an XO2-1200, if you need the additional capacity.

The boards have the JTAG interface on the side pins and also on a top header that would be handy to plug in a JTAG dongle for programming. The tiny chips are much easier to work with when they are entombed in a breakout board like this. Bigger boards with LEDs and other …read more
