The RPGA Feather dev board pairs RP2040 chip with a Lattice iCE40 FPGA for sensor fusion projects

rpga feather board

Oak Development Technologies’ RPGA Feather board integrates the Raspberry Pi RP2040 microcontroller with the iCE5LP4K FPGA from Lattice Semiconductor into a compact development board in the Adafruit Feather form factor. The iCE5LP4K FPGA is an ultra-low-power chip in the iCE40 Ultra product family designed for mobile applications such as smartphones, tablets, and handhelds, while the Raspberry Pi RP2040 microcontroller makes it much easier to program the FPGA using CircuitPython. We have seen Oak Development Technologies’ earlier forays into FPGA Feather-compatible products such as the IcyBlue board (also based on iCE5LP4K FPGA) and the Lattice FeatherWing. RPGA Feather specifications: MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ 133 MHz with 264KB SRAM FPGA – Lattice Semiconductor iCE5LP4K FPGA Logic Cells – 3,520 logic cells Memory 80 Kbits of embedded Block RAM (EBR) Distributed RAM: 640 bits 2x hardware I2C blocks and 2x hardware SPI blocks 26 I/Os for customized interfaces […]

ThingPulse Pendrive S3 ESP32-S3 USB stick comes with 128MB of storage and a capacitive spring button

ThingPulse ESP32-S3 Pendrive spring button

The Pendrive S3 is an ESP32-S3 development board in a USB stick enclosure with 128MB of flash memory and an unusual capacitive touch button. The Espressif ESP32-S3-MINI-1 module on the board integrates an Xtensa dual-core 32-bit LX7 microprocessor with support for 2.4GHz Wi-Fi and Bluetooth 5 (low-energy). The device features a capacitive touch button that can be used to trigger actions by touching the enclosure. The capacitive button isn’t visible on the exterior of the device, which helps the device maintain a low profile. You may be interested in Dani Eichhorn’s article on how he came up with the idea of using a spring for the capacitive touch button. The Pendrive S3 stick can be used as a BadUSB device for hacking and penetration testing purposes. With the aid of SuperWiFiDuck, it can perform keystroke injection attacks. All scripts can be managed and controlled wirelessly via a web interface, and […]

Raspberry Breadstick – A RP2040-based development board in a quirky form factor

Raspberry Breadstick on a breadboard

The Raspberry Breadstick is a breadstick-shaped development board that is designed for ease of use. Unlike other development boards, the Breadstick is built to fit directly on your breadboard and interface with the other electronic components in your project without the need for lengthy jumper wires. It serves to deliver a prototype that is neat, straightforward, and easy to troubleshoot. It is based on Raspberry Pi’s debut microcontroller, the RP2040, which is the same MCU chip that powers the Raspberry Pi Pico and several other boards. We recently covered the Waveshare RP2040-PiZero that comes in the Pi Zero’s form factor. The RP2040 is cheap and supports C/C++, MicroPython, and CircuitPython. The Breadstick has other interesting features such as a lineup of 24 addressable RGB LEDs with fast refresh rates, a 6-axis inertial measurement unit for collecting acceleration and rotation data, as well as 16MB of external flash storage for your […]
