Minima is a tiny Arduino Zero compatible module with SAMD21 MCU (Crowdfunding)

We’ve covered a fair amount of compact Arduino Zero compatible boards based on SAMD21 Cortex-M0+ microcontroller over the years including Exen Proto, Wemos D1 SAMD21, or Seeeduino XIAO with the latter being the smallest of them all at just 23.5 x 17.5 mm. All those boards come with a USB port (Micro USB or USB-C) by default that makes it easy to work with, but may not be ideal to integrate into projects or final products. That may be why Hamish Morley designed the Minima Arduino Zero compatible module with a size even smaller than the XIAO board at 19.8 x 16.6 mm, and the USB interface exposed through 4 pads instead of a connector. Minima specifications: Microchip SAMD21G18A 32-bit Arm Cortex-M0+ microcontroller @ 48 MHz with 256KB of flash storage, and 32KB of SRAM Expansion – 24x castellated pads (2.54mm pitch) with 18 GPIO pins, including 5x analogue capable, […]

Board::mini development tools offer a complete Vehicle-Hacking Platform (Crowdfunding)

board::mini base CAN bus automotive development board

If you are looking to connect to a vehicle’s CAN bus, then the newly launched open-source board::mini development tools include a board and expansion boards that will aid your application. BMC labs have introduced a development board based on the STM32 MCU and supporting expansion boards to increase the capabilities of the baseboard via a crowdfunding project. As mentioned earlier, the board:mini base development board features an STM32 MCU at its heart and comes with a CAN transceiver. For those who do not know what a CAN transceiver is, it just transmits and detects data on the CAN bus. The board:mini project also includes three expansion boards designed to fit on top of the base development board. The bmc::board project was born to produce development tools appropriate for both field- and industrial-prototyping work. These boards were not designed to sit on a workbench. We ourselves have a habit of strapping […]

Experiment with neurostimulation using NeuroStimDuino Arduino shield (Crowdfunding)

Neuralaxy’s NeuroStimDuino is an open-source Arduino shield that allows students, researchers, and hobbyists to study the effects of neurostimulation on muscle contraction easily and cheaply. What is Neurostimulation exactly? It works by applying short electrical pulses to the surface of the skin for the purpose of stimulating the underlying nerves and muscles. Neurostimulation has several uses including a treatment called Functional Electrical Stimulation (FES) therapy to help restore mobility in the paralyzed limb muscles of stroke victims and those who have suffered spinal cord injuries, and studies are being carried out to better understand how it can be leveraged for pain reduction and sensory feedback. NeuroStimDuino hardware specifications: MCU – Microchip dsPIC33F 16-bit microcontroller (40 MIPS) with 256 KB flash memory Two independent 2mm output jack per board with: Adjustable current output range – +/- 25 mA, resolution 250 µA/step Adjustable stimulation frequency range – 1 – 100 Hz, pulse-width […]

Piunora has the guts of a Raspberry Pi 4 with Arduino form factor, M.2 PCIe socket (Crowdfunding)

The Raspberry Pi 4 is a pretty cool board, but if you wished it was just a bit smaller, and you could use the PCIe interface exposed by the Broadcom BCM2711 processor more easily, Timon has designed Piunora carrier board for the Raspberry Pi Compute Module 4. The solution provides a board with the guts of Raspberry Pi 4 SBC but using the Arduino form factor including access to the six ADC pins, and an M.2 socket with the PCIe signal from the Broadcom SoC. Piunora carrier board specifications: SoM compatibility – Raspberry Pi CM4 module with Broadcom BCM2711 quad-core Cortex-A72 processor @ 1.5 GHz, 1 to 8GB RAM, optional 4GB to 32GB eMMC flash, optional wireless module with 802.11b/g/n/ac WiFi 5 and Bluetooth 5.0 Storage – 1x MicroSD card socket (for the OS when using Raspberry Pi CM4Lite system-on-module) Video Output – 1x HDMI 2.0 port up to 4Kp60 […]
