The Visible Lisp Computer Runs on Adafruit ItsyBitsy M0 Board

Specified in 1958, Lisp is one of the oldest programming languages, and it does not appear to be widely used anymore. But if you want to play around with the 61 years old language, you may want to do so in a neat way via the Visible Lisp Computer, a Lisp interpreter that displays the contents of the Lisp workspace on an OLED display. It is a modified version of Technoblogy’s uLisp interpreter for Arm boards designed to run on  Adafruit ItsyBitsy M0, or other boards based on Microchip ATSAMD21E MCU on a prototyping board, connected to a 64×48 OLED display over I2C. uLisp gives you a workspace of 3072 free Lisp objects (each of 8 bytes) on this hardware, which exactly matches the 3072 pixels (64×48) from the display.  Having said that the program would also work on larger SSD1306-based OLED displays. The display shows free Lisp objects in […]

Icarus IoT Board Features nRF9160 GPS + NB-IoT SiP in Adafruit Feather Form Factor

The new Icarus IoT board from Actinius, uses the Nordic nRF9160 SiP, a powerful yet low power system in a package designed for use with GPS and LTE-M & NB-IoT cellular data, also found in Ruuvi node which we covered a few months ago. The board’s purpose is for mobility and ease of project tracking anywhere, and can be found in application scenarios such as fleet management and security, cargo tracking, or asset monitoring, and many more. The board has power inputs for solar panel, USB or LiPo/Li-Ion Battery, which widens the boards mobile nature, and on-site, in-the-field capability. Since the form factor follows Adafruit Feather, the Icarus board benefits of additional component options for prototyping and DIY electronics projects. The nRF9160, by Nordic Semiconductor, is a SiP (System in a Package) that carries an extensive line of embedded software and hardware. As we had reported the nRF9160 SiP low-power […]

SAMD21 MINI / Wemos D1 SAMD21 M0 Mini Development Board Sells for $7 and Up

Microchip / Atmel SAMD21 Arm Cortex-M0+ microcontroller has been around for several years, and we covered various boards based on the MCU include the official Arduino Zero launched in 2014, Arduino Tian, and the tiny SAM 15×15 or Exen Proto boards among others. Another SAMD21 development board has now shown up on Electrodragon website: SAMD21 Mini Development Board sold for $14.50 on the website, but you’ll also find it, under the RobotDyn or Wemos brand on Aliexpress for $7.05 and up. SAMD21 Mini Board / WeMos D1 SAMD21 M0 Mini Specifications: MCU – Microchip ATSAMD21G18 Arm Cortex-M0+ microcontroller @ 48 MHz with 32KB data RAM, 256KB flash USB – 1x micro USB port for power and programming Expansion 2x 14-pin headers with 19x digital I/O (including 12x PWM), 6x Analog I/O 3.3V logic level Programming – 6-pin ISCP connector Misc – Power, Tx and Rx LED’s, button Power Supply Input […]

Programmable USB Hub Power Adjustable with Built-In Dev Board (Crowdfunding)

Capable Robot Components has launched its Crowd Supply campaign for the Programmable USB Hub in June of 2019. The hub is a feature rich and component rich USB hub that has a dev board built-in. The entire system is housed in an extruded aluminum case, with all the numbering and lettering and port attachments in brilliant white.  Control power and data flow, directly through the unit. The first 40 units are sold out. There seem to be good reasons why these USB Hubs sell out fast.  There was an in-depth article written on a similar hub some time ago.  Inside the enclosure is an array of functionality packed neatly onto a small board. There are 4x USB 2.0 ports that are High-Speed downstream ports and 1x upstream port, a 5th endpoint on the USB hub exposes 2 12C buses via Sparkfun Qwiic connectors, the UART and 2X GPIO. The input power is […]

Microchip SAMA5 based Giant Board Launched on Crowd Supply for $50 and Up

Earlier this year we gave you details about some new development board, most especially about the Giant board. A tiny single board computer that runs Linux on Arm Cortex-A5 processor.  This super tiny single-board computer (SBC) is based on the Adafruit Feather form factor. Unlike its name, the giant board is actually a small microchip. And it packs an awful lot of power for its size. The news is that it has launched on Crowd Supply for $50 and up. In addition, the giant board implements the power of size, which makes it unique. It squeezes SBC into a package the size of a microcontroller board. This will in turn relax memory, storage, and processing constraints. Consequently allowing you to effectively work on your projects. Another thing to know about the Giant Board is that it runs full Debian Linux.  Giving developers and users access to an endless number of […]

FOSSASIA 2019 Schedule – March 14-17

As its name implies, FOSSASIA is a Free and Open Source Software  event taking place every year in Asia, more specifically in Singapore. I first discovered it last year, and published a virtual FOSSASIA 2018 schedule last year to give an idea about the subjects discussed at the event. It turns out FOSSASIA 2019 is coming really soon, as in tomorrow, so I’m a bit late, but I’ll still had a look at the schedule and made my own for the 4-day event.  Thursday – March 14, 2019 10:05 – 10:25 – For Your Eyes Only: Betrusted & the Case for Trusted I/O by Bunnie Huang, CTO Chibitronics Security vulnerabilities are almost a fact of life. This is why system vendors are increasingly relying on physically separate chips to handle sensitive data. Unfortunately, private keys are not the same as your private matters. Exploits on your local device still have […]

Tiny Giant Board Runs Linux, Follows Adafruit Feather Form Factor

If you want a tiny single board computer that runs Linux on Arm Cortex-A processor, some options include Raspberry Pi Zero (W), PocketBeagle, or FriendlyElec NanoPi Duo with the latter being smaller and more powerful than RPi Zero although it lacks video output. Another potential option that may become available soon is the Giant Board, which as its name clearly does not imply, is a really tiny board powered by Microchip Atmel SAMA5 Cortex-A5 processor, and leveraging Adafruit Feather form factor. Giant board preliminary specifications: SiP – ATSAMA5D27C-D1G with Microchip SAMA5D2 Arm Cortex-A5 Processor 500MHz, 128MB DDR2 RAM Storage – Micro SD slot for OS and storage Peripherals & I/Os 6x 12-Bit ADC with 3.3V Reference 4x 16-Bit PWM ADC external trigger PWM external trigger 1x I2C, 1x SPI, 1x UART Misc- Power button Power Supply 5V via micro USB port 3.7V LIPO support for portable projects The Microchip / […]
