Tiny FPGA BX – A Tiny, Open Source FPGA development board for Makers

The TinyFPGA boards from Luke Valenty (TinyFPGA) are a series of low-cost, open-source FPGA development boards. These boards offer an inexpensive way to get an introduction to the world of FPGAs.

If you have ever considered working with an FPGA before, you will know how difficult they could be especially for those new to the game. TinyFPGA boards are an excellent way to kickstart development with them. They are breadboard friendly, and one can put up a simple circuit around them before adding things like sensors or actuators.

The TinyFPGA boards are currently made up of about three series – The TinyFPGA A1 that offers an X02-256 containing 256 logic cells; the A2 sports with an X02-1200 of about 1200 logic cells, and lastly the B2 boats an ICE40LP8K with 7680 logic cells. They are low cost in nature, costing about $12,00, $18,00 and $38.00 respectively. The latest upcoming release to the TinyFPGA board family is the TinyFPGA BX.

Like the other Tiny FPGA Boards, the Tiny FPGA BX boards is quite flexible and powerful. The BX boards are intended for the maker’s community. The BX module allows one to design and implement a digital logic circuit in a tiny form-factor, and it’s perfect for building with breadboards or custom PCBs.

The TinyFPGA BX shares close similarities with the TinyFPGA B2 and are both based on the Lattice ICE40LP8K FPGA Chip with about 7680 logic cells. The BX board will offer an incredible power to project development and allows to achieve things not usually expected on traditional microcontroller boards at a fraction of the cost.

According to Luke, the TinyFPGA BX prototype boards are currently being manufactured. The PCBs have been fabricated and are now waiting for assembly.

The BX measure at 0.7 by 1.4 inches and comes with a built-in USB interface, and preloaded with a USB Bootloader. It is expected to have 8Mbit of SPI Flash with only 5Mbit available for user applications.

The following are some of the available board specifications:

  • ICE40LP8K FPGA
    • 7,680 4-input look-up-tables
    • 128 KBit block RAM
    • Phase Locked Loop
    • 41 IO pins
  • Small, breadboard friendly form-factor
    • 0.7 by 1.4 inches
  • Built-in USB interface with open source USB bootloader
  • 8MBit of SPI Flash with 5MBit available for user applications
  • Integrated 3.3v and 1.2v regulators
    • 3.3v LDO regulator can supply up to 300ma of current to support external peripherals
  • Ultra-Low-Power 16MHz MEMs Oscillator
    • 1.3ma active power
    • 50ppm stability

These TinyFPGA boards offer an inexpensive way for hackers and makers to get an introduction to the world of FPGAs. And, with their small size, these boards can provide an easy way to add some programmable logic to a small project.

FPGA gives us the power to add real deal hardware functionality to our project, unlike with Microcontroller, where those features can only be added to a bit of software banging. The TinyFPGA Bx boards are still not fully launched yet, so now price point is currently available but is expected to share similar costing with the TinyFPGA B2 at $38.00.

More information about the project launch can be found on the crowdsupply page and also on the hackaday board page announcement. If you are interested in getting introduced to the world of FPGA, this guide from Luke is an excellent way to kickstart your adventure.

The ezPixel is an Upcoming FPGA based WS2812B Controller Board

FPGAs are field programmable gate arrays which basically means they are reconfigurable hardware chips. FPGAs have found applications in different industries and engineering fields from the defence, telecommunications to automotive and several others but little application in the maker’s world. Mostly, as a result of being largely difficult and high cost as compared to the likes of Arduino, but the introduction of the ezPixel and other similar FPGA boards is making this a possibility.

Prototype modules.

The ezPixel board, by Thomas Burke of MakerLogic, is a small size FPGA based circuit board that can be used to drive up to 32 strings of WS2812Bs, for up to 9,216 LEDs in total, a very first of its kind. These WS2812B programmable color LEDs have been a phenomenon in the maker’s world, being used in various Led Lights and creating of various Light Artworks. These popular LEDs comes in strings that can be cut to any length, and only require a single wire serial data connection to control all the lights in the string individually, and multiple strings can be stacked together to create large two-dimensional displays.

ezPixel description.

Most WS2812B controller boards can be used to control up to hundreds of these LEDs, but not thousands of them. The ezPixel board is a perfect fit for applications that use thousands of these LEDs. The ezPixel board is powered by the Intel MAX FPGA, a single chip small form factor programmable logic device with full-featured FPGA capabilities, and it’s designed to interface with other Micro-controllers or any SPI/UART host device. The ezPixel board serves as bridge between microcontrollers and long WS2812B strings. A user sets the length of each string using simple commands that are sent via the SPI or USB/UART communication link.

The following below are the features of the ezPixel:

  • WS2812B Smart Pixel Controller.
  • Up to 32 Strings can be controlled independently.
  • Up to 9216 LEDs can be controlled.
  • Communication:
    • USB/UART Interface.
    • SPI Interface.
  • Read/Write Pixel Memory.
  • FPGA – Intel MAX10M08 FPGA.
  • Dimension:
    • 1” x 3” (25mm x 76mm).
  • SPI Flash.

The ezPixel can run as a standalone display controller as a result of its serial flash memory chip, and this board is slated for a crowdfunding campaign in early 2018.

MicroZed is a Powerful and Low-Cost ARM + FPGA Linux Development Board

MicroZed is a low-cost development board from Avnet, the makers of the $475 ZedBoard and the entry level MiniZed development boards. Its unique design allows it to be used as both a stand-alone evaluation board for basic SoC experimentation or combined with a carrier card as an embeddable system-on-module (SOM).

The MicroZed processing system is based on the Xilinx Zynq®-7000 All Programmable SoC. The Zynq®-7000 All Programmable SoC (AP SoC) family integrates the software programmability of an ARM®-based processor with the hardware programmability of an FPGA, enabling key analytics and hardware acceleration while integrating CPU, DSP, ASSP, and mixed-signal functionality on a single device. The processing system offers the ability to run standard operating systems like Linux, real-time operating systems, or a combination of the two. The programmable logic provides a unique capability to create custom interfaces or custom accelerators. Together, they provide a versatile, performance optimized solution.

ZedBoard™ is a low-cost development board for the Xilinx Zynq®-7000 All Programmable SoC. This board contains everything necessary to create a Linux, Android, Windows® or other OS/RTOS-based design all at a cost of $495. The MicroZed sells for $199 with close performance and functionality with the ZedBoard. MicroZed contains two I/O headers that provide connection to two I/O banks on the programmable logic (PL) side of the Zynq – 7000 AP SoC device. In stand-alone mode, these 100 PL I/O are inactive. When plugged into a carrier card, the I/O are accessible in a manner defined by the carrier card design. The MicroZed board targets application in the areas of general FPGA evaluation and prototyping, embedded SOM applications, embedded vision, test & measurement, motor control, software-defined radio, industrial network and industrial IoT.

The Zedboard is based on Zynq-7020 with 85K logic cells while the MicroZed is based on the lower Zynq-7010 with a 28K logic cell. The MicroZed has 1GB RAM instead of 512 MB on the ZedBoard and has lesser interfaces as compared to the ZedBoard.

The following below are the features of the MicroZed SoM:
