Getting Started with MicroPython on ESP32 – Hello World, GPIO, and WiFi

I’ve been playing with several ESP32 boards over the months, and tried several firmware images. I started with a tutorial for Arduino Core on ESP32, a few month later I tested ESP32 JavaScript programming with Espruino on ESPino32 board, and recently Espressif Systems sent me ESP32 PICO core development board powered by their ESP32-PICO-D4 SiP, and while I took some pretty photos, I had not used it so far. So I decided to go with yet another firmware, and this time, I played with MicroPython on ESP32, and will report my experience with basic commands, controlling GPIOs, and WiFi in this getting started post. Flashing Micropython Firmware to ESP32 Board Source code is available on Github, as a fork of MicroPython repo as ESP32 support has not been upstreamed yet. We could built the firmware from source, but there’s also a pre-built binary which you can download on MicroPython website. […]

STEGO BOARD Enables Neat Prototypes with Development Boards and Accessories (Crowdfunding)

If you’ve ever created a quick prototype for your own use, or for your company, you may have based it on a development board, and added some extra modules or add-on modules, as well as potentially accessories such as hard drives or power supply. Software is complete and it works, but it may look like a mess, and transporting it may cause cables to disconnect or other problems. STEGO BOARD should help in this case. It’s some kind of mounting systems compatible with the most common boards like Raspberry Pi 3, Rock64, or ASUS Tinkerboard, mini-ITX motherboards, mini PCs with VESA mounts, 2.5″ and 3.5″ drives, and so on. So you can create prototypes like the ones below. Six different products are available: STEGO BOARD 102 – 2 layers of the smaller board with 106 parts (stands, screws, zip ties). Can be used with mini PC, development board, up to […]

The New Pi-Top Modular Laptop includes a 14″ Display, Sliding Keyboard, and Better Cooling

Pi-Top was first launched in late 2014 via an Indiegogo crowdfunding campaign, as a modular DIY laptop powered by a Raspberry Pi board. It’s equipped with a 13.3” LCD screen with 1366×768 resolution, and uses a sliding top cover placed between the display and the keyboard where you could insert your Raspberry Pi with enough space for extra hardware. This is a good week for DIY ARM laptops, as after the launch of Olimex TERES-I laptop yesterday, Pi-Top team has announced a new version of Pi-Top modular laptop with an larger 14″ display with 1920×1080 resolution, a sliding keyboard, and better cooling with a passive cooling unit for the Raspberry Pi 3 board. Pi-Top 2017 laptop specifications: Display – 14” full HD LCD screen with 1920 x 1080 resolution, 180° screen angle range Keyboard – 105mm sliding keyboard for internal access (US layout) Touchpad – 104x75mm trackpad with Gesture Control […]

GNUBee Personal Cloud 2 is a DIY NAS Supporting up to Six 3.5″ SATA Drives (Crowdfunding)

GNUBee Personal Cloud 1 is a DIY NAS powered by Mediatek MT7621A MIPS processor that supports up to 2.5″ SATA drives, and runs free and open source software. It was first introduced in March of this year through a CrowdSupply campaign. The developers are now back with GNUBee Personal Cloud 2 (GB-PC2) with pretty much the same features, but instead of being designed for 2.5″ drives, it supports up to six 3.5″ drive that should offer either more capacity, or a lower total price for an equivalent capacity. GB-PC2 NAS specifications: Processor – MediaTek MT7621A dual core, quad thread MIPS processor @ 880 MHz, overclockable to 1.2 GHz System Memory – 512 MB DDR3 (max supported by MT7621) Storage – SD card slot tested up to 64 GB, 6x 3.5” SATA HDD or SSD (recommended RAID 0 or 1 under LVM, MD, or Linux MD RAID 10) Connectivity – 3x […]

Dragonwally is a Stereoscopic Computer Vision Mezzanine for 96Boards CE Boards

Hardware based on 96Boards specifications may not have the number of sales as Raspberry Pi or Orange Pi boards, but there’s heavily used by Linaro member and other developer working on bleeding edge software. More and more companies are designing boards compliant with the standard, and several new mezzanine expansion boards such as Secure96, were showcased at Linaro Connect SFO 2017, and are yet to be show up on 96Boards Mezzanine page. Another 96Boards mezzanine expansion board in development is Dragonwally, designed for stereoscopic computer vision, currently used with DragonBoard 410c board, and targetting applications such as object recognition, people counting, access control, or driver identification and safety. DragonWally DW0 board specifications: MIPI DSI interface with high speed connector 2x 5MP cameras 1x USB port 96Boards CE compliant The two Brazilian developers working on the project interfaced it with DragonBoard 410c running Linaro Debian, and using OpenCV and Python for […]

NComputing RX300 Thin Client Review – Part 2: Hardware Setup, Windows Server 2016

Ncomputing RX300 is a thin client based on Raspberry Pi 3 board, allowing to run Windows operating systems on a powerful server with the Raspberry Pi 3 handling the display, audio, and keyboard/mouse inputs. The company sent me a sample for review, and I checked out the hardware and accessories in the first part entitled “NComputing RX300 Thin Client Review – Part 1: Unboxing and Teardown“, so in the post I’ve started the thin client, and connected it to vSpace Pro server. Hardware Setup RX300 uses the same peripherals as any mini PC, so I connected USB keyboard and mouse, an Ethernet cable (WiFi is also possible), and the power adapter. You could also connect other devices, and I added a USB flash drive which, as we’ll see later, will be properly recognized by the server. I was also sent a USB to VGA adapter that you can connect to […]

Orange Pi Lite Based Seedi Retro Gaming Console Takes Your Old DVDs or CD-ROMs (Crowdfunding)

Shenzhen Xunlong’s Orange Pi family is a nice collection of low costs ARM Linux development boards that can be used in all sort of projects, just like Raspberry Pi boards, but cheaper at the cost of requiring more skills, and/or efforts to complete a project. One popular use for Orange Pi boards is retro gaming thanks to community supported images like RetrOrange Pi supporting games for Atari, Amiga, DreamCast, and other consoles. The implementation looks good enough for startups to sell their own products based on Orange Pi hardware and RetrOrangePi software, as we’ve already seen with RetroEngine Sigma Retro Game Console which had a very successful Indiegogo campaign with $629,368 USD raised. “Seedi Team” has now launched their own game console apparently based on Orange Pi Lite, but it’s a little different as instead of copying “ROMs” , you can simply insert your old CD-ROMs or DVDs. Seedi game […]
