Lattice FeatherWing – An iCE40-powered add-on FPGA board for Adafruit Feather

Oak Development Technologies has recently announced Lattice FeatherWing – An iCE40-based development board designed to be controlled by Adafruit Feather. Previously we wrote about the IcyBlue Feather V2, a standalone development built around a Lattice Semi iCE5LP4K FPGA. But this FeatherWing board is designed to add functionality to your existing Adafruit Feather board. The Lattice FeatherWing expands your Adafruit Feather with a Lattice iCE5LP4K FPGA. It connects and gets programmed over SPI so you can use all the FPGA’s GPIO pins through the header blocks. There’s also a built-in RGB LED directly connected to the FPGA’s open-drain pins, for visual feedback. Previously, we have written about many Lattice Semi FPGA-based development boards, such as the tinyVision.ai Pico-Ice board, Silicon Witchery S1, and ULX3S Education Board. Feel free to check those out if you want a standalone FPGA board. FPGA – Lattice Semi iCE40 Family ICE5LP4K-SG48ITR Logic Cells – Approximately 3520 logic cells Memory – 80 Kbits […]

IcyBlue Feather V2 board features Lattice Semi iCE5LP4K FPGA in Adafruit Feather form factor

The IcyBlue Feather V2 from Oak Development Technologies is a powerful and compact dev board that combines the Lattice Semi iCE5LP4K FPGA with the Adafruit Feather form factor. This unique combination allows this FPGA board to be compatible with the Adafruit FeatherWings ecosystem, providing functionalities such as additional GPIOs, displays, connectivity modules, and more. This new board features a USB-C port for powering and programming the FPGA. Additionally, it features two hardware I2C and SPI blocks that do not consume FPGA resources while operating. The board also includes 22 accessible GPIOs, a bright RGB LED for status indication, and two user-programmable LEDs. Previously, we have discussed many similar tiny FPGA-based development boards, such as the Lattice Semi MachXO2 FPGA, tinyVision.ai Pico-Ice board, Silicon Witchery S1, and ULX3S Education Board. Feel free to explore these if you are looking for similar options. IcyBlue Feather V2 Specification FPGA – Lattice Semi iCE40 […]

LimeSDR Mini 2.0 USB SDR board gets an upgrade to Lattice Semi ECP5 FPGA (Crowdfunding)

The LimeSDR Mini is an open-source hardware full-duplex USB SDR board based on Intel Altera Max 10 Altera FGPA that was introduced in 2017 on Crowd Supply and raised close to $2 million US dollars. Since it has been used in various projects including digital TV transmitters. Lime Microsystems is now back on Crowd Supply with the similar-looking LimeSDR Mini 2.0 replacing the MAX 10 FPGA with 16K logic gates with a more powerful and capable Lattice Semiconductor ECP5 FPGA with 44K logic gates while keeping the company’s LMS7002 RF transceiver. LimeSDR Mini 2 specifications: FPGA –  Lattice Semi ECP5 (LFE5U-45F) with 44K logic gates, 108 sysMEM blocks (18kb), 1,944 Kb embedded memory, 351 Kb distributed RAM bits Storage –  4 MB flash memory for data; 2x128KB EEPROM for RF transceiver MCU firmware and data RF Lime Microsystems LMS7002M RF transceiver Tx & Rx SMA connectors Frequency range – 10 […]

Cynthion board enables USB Hacking through Lattice ECP5 FPGA (Crowdfunding)

Update 16/02/2023: The LUNA board has been renamed to Cynthion, but the gateware framework continues to be called LUNA. Several USB hacking/debugging boards were launched in 2020 either based on microcontrollers or FPGA with the likes of Tigard (FTDI FT2232HQ), Ollie (STM32F042), Glasgow Interface explorer (Lattice Semiconductor iCE40), or Protocol Droid (STM32). All those were launched on Crowd Supply, and there’s now another one with LUNA “multi-tool for building, analyzing, and hacking USB devices” based on a  Lattice Semiconductor LFE5U-12F ECP5 FPGA that raised over $100,000 in a few days. Cynthion hardware specifications: FPGA- Lattice Semiconductor LFE5U-12F ECP5 FPGA with 12K LUTs System Memory – 64 Mbit (8 MiB) RAM for buffering USB traffic or for user applications Storage – 32 Mbit (4 MiB) SPI  flash for PC-less FPGA configuration USB – 3x High-Speed USB interfaces, each connected to a USB3343 PHY capable of operating at up to 480 Mbps.

$180 Zeal 8-bit Computer Complete Edition is an all-in-one retrocomputing platform based on the Zilog Z80 microprocessor

The Zeal 8-bit Computer Complete Edition is a system that aims to bring retrocomputing to the modern age with the aid of a motherboard built around the Zilog Z80 microprocessor and several peripherals. The Zeal 8-bit Computer project began in early 2021 and has been released in bits and pieces since then. Now, a finalized version tagged the “Complete Edition” is ready for release to the public. It promises a modern retrocomputing experience with the simplicity of retro computers and support for relatively recent features such as VGA graphics, TF cards, and NOR flash. The Zeal 8-bit Computer Complete Edition includes the following components: the Zeal 8-bit Computer motherboard, the Zeal 8-bit Video Board, and a 3D-printed enclosure with a touch sensor for turning the board on/off. The Zeal 8-bit Video Board is based on a Lattice ECP5 FPGA and can output up to 65,536 colors via VGA. It also […]
