RasPad is a Tablet Kit for Raspberry Pi 3 B+ and Other Development Boards (Crowdfunding)

Many people interesting in coding and working on projects with the Raspberry Pi just likely connect the board to a monitor, USB keyboard and mouse, and to a power adapter, but if you are interested in having some more compact and portable RasPad tablet kit may be for you. The kit is compatible with Raspberry Pi boards, including the latest Raspberry Pi 3 B+, as well as other Arm/x86 Linux development boards including Tinker Board, LattePanda or BeagleBone Black. [Update: The design likely only works with RPi form factor, so if you use other boards with HDMI output, you may have to leave them out of the housing] RasPad key features: Display – 10.1″ IPS touch screen Video – HDMI port Audio – 2W speaker, audio jack Misc – 3 buttons (volume/brightness +, volume/brightness -, power), micro “USB touch” port Battery – Good for about 3 hours Power Supply – […]

TinyFPGA BX is a Tiny Open Source Hardware iCE40 FPGA Board that Fits into a Breadboard (Crowdfunding)

Last Friday, I wrote about Fipsy, a $10 breadboard-friendly FPGA board powered by Lattice Semi MachXO2 FPGA with 256 LUTs, but I then remember I had covered a board somewhat similar with TinyFPGA board last year based on either the same MachXO2-256 (TinyFPGA A1), or a slightly more powerful MachXO2-1200 FPGA (TinyFPGA A2). It happens the developer is now running a crowdfunding campaign on Crowdsupply for TinyFPGA BX board, which can be used with a breadboard, and is powered by Lattice Semi ICE40LP8K FPGA that will offer more flexibility thanks to 7,680 LUTs. TinyFPGA BX specifications: FPGA – Lattice Semi ICE40LP8K FPGA with 7,680 four-input look-up-tables, 128 KBit block RAM, Phase Locked Loop Storage – 8 MBit of SPI Flash Expansion 2x 14-pin header for I/Os, GND and Vin 21x solder pads on back of the board USB – 1x micro USB 2.0 FS port for programming Oscillator – 16 […]

Espressif ESP-ADF Audio Development Framework for ESP32 Supports Baidu DuerOS, and Soon Amazon Alexa, Google Assistant, etc…

Espressif Systems have been working on audio applications like Smart Speakers based on ESP32 WiSoC with hardware development kits like ESP32-LyraTD-MSC Audio Mic HDK, and I could test it with Baidu DuerOS using Mandarin language. However, at the time (February 2018), there was not much else that could be done with the hardware kit, since no corresponding ESP32 audio software development kit had been made available. This has now changes since Espressif has just released ESP-ADF Audio Development Framework on Github. The framework will support the development of audio applications for the Espressif Systems ESP32 chip such as: Music player or recorder handling MP3, AAC, WAV, OGG, AMR, SPEEX … audio formats Play music from network (HTTP), storage (SD card), Bluetooth A2DP/HFP Integration with Media services such as DLNA, Wechat, etc.. Internet Radio Voice recognition and integration with voice services such as Alexa, DuerOS, Google Assistant As we can see […]

Fipsy is a $10 Breadboard-Friendly FPGA Board for Education (Crowdfunding)

We’ve already seen several cheap FPGA boards in the past with the $25 miniSpartan3 (Xilinx), $34 Spartixed (Xilinx), or 40 Euros Olimex iCE40HX8K-EVB boards (Lattice), but if you have a really tight budget you can now plat with FPGA for just $10 thanks to Fipsy board. With its 256 LUTs Lattice Semi MachXO2 FPGA, you’ll be limited to what you can do for specific projects, but it could be useful to teach yourself or students FPGA programming, especially it also happens to be breadboard-friendly. Fipsy specifications: FPGA – Lattice Semiconductors MachXO2 (LCMXO2-256HC-4SG32C) FPGA @ 269 MHz max. with 256 LUTs, 2 kbit Distributed RAM, 32 LABs (Logic Array Blocks) Programmable by SPI and I2C Expansion – 2x 10-pin header supporting various interfaces including: LVCMOS 3.3/2.5/1.8/1.5/1.2 LVTTL LVDS Bus-LVDS MLVDS RSDS LVPECL SSTL 25/18 HSTL 18 Schmitt trigger inputs, up to 0.5 V hysteresis Misc – Onboard LED Operating Supply Voltage – 3.3 […]

Shedbuilt Binary Blob-Free Linux Distribution Works with Allwinner H3/H5 Boards (Orange Pi, Libre Computer)

Most open source Linux distributions are only partially open source, as while most packages will be built from publicly available source code, they usually come with closed source binary blobs for GPU drivers, wireless module firmware and so on. Shedbuilt is described as “a decentralized, self-hosting GNU/Linux for Arm devices built from the latest upstream sources”, and as the developer (Auston Stewart) explains – see comments section – it does not contain any binary blob. Eventually the distribution may support more boards, but for now, the current System 1 “Amano” release supports four Allwinner H3/H5 boards: Orange Pi PC, Orange Pi One, Orange Pi PC 2, and Libre Computer ALL-H3-CC “Tritium”. Orange Pi Lite (with WiFi) and Libre Computer AML-S905X-CC “Le Potato” images are said to be coming soon. You can download the SD card images and access documentation on Shedbuilt.net. The Linux distribution relies on Shedmake script to automate […]

$19.50 BPI:bit ESP32 Board is Inspired by BBC Micro:bit, Compatible with Webduino and Arduino IDE

BBC micro:bit board for education was first unveiled in 2015, before starting to be given away to UK students, and later sold for about $19 in 2016. The board supports Bluetooth connectivity, includes an array of 25 LEDs, as well as a specific 20-pin edge connector also featuring 5 large holes (rings) for 3 I/Os and power. So far I had not seen any clones or alternative boards inspired from the design, as we see for Arduino or Raspberry Pi boards. But SinoVoIP (Banana Pi) has changed that with their BPI:bit clearly inspired from the Micro:bit, but offering both WiFi and Bluetooth connectivity via an ESP32 module. Hardware specifications: Wireless module – ESP-WROOM-32 module with WiFi and Bluetooth LE connectivity LEDs – 25x RGB LED array Sensors – 2x light sensors, thermistor, 9-axis accelerometer / gyroscope / compass (MPU-9250) Expansion – 3 digital/analog I/O rings, 3V/GND ring, 20-pin edge connector […]

$1.40 EDMINI Development Board Features LogicGreen LGT8F328P MCU Compatible with ATMega328P/Arduino

Arduino compatible boards are normally using Microphip Atmel microcontrollers, but as we’ve see with GD32 clone of STM32 MCU, some companies are making MCU clones too, usually with some improvements, and LogicGreen designed LGT8F328P micro-controller (mostly) compatible with Atmel ATMega328P micro-controller and adding features such as DAC output, PWM specific features, a computing accelerator (DSC), and others. The MCU also runs at double the clock speed (32 MHz). I found out about the new MCU via Electrodragon selling EDMINI Arduino compatible development board based on LGT8F328P micro-controller for $1.40. The board looks to be a clone of Arduino Pro Mini. Main specifications for EDMINI board: MCU – LogicGreen 8F328 (LGT8F328P) MCU – 99% compatible with ATMEGA328P MCU Expansion – Same pins as Arduino Pro Mini plus SWD/SWC pins, PE4/PE5 pins Misc – On-board power LED, D13 LED, reset button Power Supply – 5V RAW as VCC directly in; regulated 3.3V […]
