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

Minima Arduino Zero Module

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, […]

BLUETTI EP500 is a power bank & UPS for home appliances (Crowdfunding)

Bluetti EP500

Many people are using a power bank to extend the battery life of their mobile device(s), and there are also laptop power banks which higher capacity and support for 12V and/or 19-20V besides the usual 5V. But BLUETTI EP500 & EP500Pro go up a notch as the systems aim at powering multiple home appliances or be used as UPS in case of power failure, or whenever you need to use tools or appliances away from the mains. BLUETTI EP500 & EP500Pro specifications: Control system based on Texas Instruments C2000 dual-core Arm+DSP real-time microcontroller AC Rated Power EP500 – 2000W (peak 4800W less than 500ms) EP500Pro – 3000W (peak 6000W less than 500ms) Power Input EP500 600W max, 100-264V AC via AC input – Charging time around 9 to 10 hours 1,200W max via PV input or T500 input (55-145V DC, 20A) – Charging time around 5 hours with solar panels […]

Raspberry Pi case embeds 192 programmable LEDs, speaker, microphone, and sensors (Crowdfunding)

LumiCube Raspberry Pi LED Enclosure

Most Raspberry Pi enclosures are designed to protect your board from dust, provide easy access to ports, and in other cases, ease the installation of hard drives or SSDs. But Abstract Foundry’s LumiCube does much more, and just calling it a case or enclosure is an understatement, as while it does house a Raspberry Pi, it also comes with 192 programmable LEDs placed over 3 panels, a speaker, a microphone, as well as several optional motion & environmental sensors, and a small 2-inch LCD display. LumiCube specifications: Acrylic base 3x RGB LED panels with 64 programmable LEDs each Audio – 2W speaker and microphone Display (optional) – 2-inch 320×240 IPS screen for system parameters or other info (e.g. sensor data) or images. Note that it can now show the Raspberry Pi desktop Sensors (optional) – Light & gesture sensor, BME280 temperature, humidity and pressure sensor, BNO055 IMU (accelerator and tilt […]

ZimaBoard Intel Apollo Lake SBC and micro server goes for $69.99 and up (Crowdfunding)

ZimaBoard

We’ve had our fair share of low-cost x86 SBCs in recent years, mostly based on Intel Cherry Trail processor, with the likes of Atomic Pi and Rock Pi X. Ice Whale Technology has come up with its own low-cost Intel single board computer with ZimaBoard “single board server” as it mostly has network storage applications in mind, but with a 4K capable mini DisplayPort connector it could also be used as a standard SBC or mini PC. There are two versions of the board both with Apollo Lake processors: ZimaBoard 216 with a dual-core Celeron N3350 coupled with 2GBRAM and 16GB eMMC flash, and ZimaBoard 832 powered by a quad-core Celeron N3450 with 8GB RAM and 32GB storage.
