Using GPIOs on NanoPi NEO 2 Board with BakeBit Starter Kit

NanoPi NEO 2 is a tiny 64-bit ARM development board powered by Allwinner H5 processor. FriendlyELEC sent me a couple of NEO 2 samples together with their BakeBit Start Kit with a NanoHat and various modules via GPIOs, analog input or I2C. I’ve already tested both Armbian with Linux 4.11 and Ubuntu Core Qt with Linux 3.10, and ran a few benchmarks on NanoPi NEO 2. You would normally prefer to use the Armbian image with Linux mainline since it provided better performance, but at the time I was told GPIO support was not there. Configuring NanoPi NEO 2 board with BakeBit library So this week-end, when I decided to test GPIO support and BakeBit Starter Kit, I decided to follow this advice, especially nanopi-neo2-ubuntu-core-qte-sd4g-20170329.img.zip image is still the recommended one in the Wiki. So I went with that image. I’ll use Python examples from Bakebit library, but if you […]

Xiaomi Mi Band 2 Fitness Tracker Adds an OLED Display, Promises 20-day Battery Life

I’m not a big fan of fitness trackers without display that require you to monitor your daily progress on your smartphone, and that’s probably why when Xiaomi released their first fitness band I was not quite as interested, but now the Chinese company has released Mi Band 2 with an OLED display, an heart rate monitor,  IP67 ingress protection rating, and a 20-day of battery life for just 149 RMB ($23). Mi Band 2 key features: Fitness, heart rate and sleep tracker OLED display, view time, step count, heart rate 20-day battery, IP67 water resistant ADI accelerometer and optical heart rate sensor Anodized 0.05mm ultra-thin button Upgraded pedometer algorithm Hypoallergenic silicone band 2nd gen Bluetooth 4.0 for faster, stable connections It’s still good to be able to gather your fitness data over time, and you can do so with Mi Fit app for Android or iOS. The downside with an […]

BPI-GSM Arduino Compatible Board Integrates a GSM & GPS Module, Sensors and an OLED Display

Banana Pi team has come up with another board, but this time it does not run Linux or Android, as they’ve made an Arduino compatible board called BPI-GSM based on Atmel ATmega2560 MCU with a light sensor, DHT22 temperature and humidity sensor, and a GSM/GRPS & GPS module powered by a LiPo battery. BPI-GSM board specifications: MCU – Atmel ATmega2560 8-bit AVR MCU @ 16 MHz with 256 KB flash, 8KB SRAM, 4KB EEPROM Connectivity – Simcom SIM808 GSM, GPRS, and GPS module + SIM card slot + Sensors – DHT22 temperature and humidity sensor, light sensor Display – OLED display Expansion headers – 54x digital I/O (including 14x PWM), 16x analog input, 4x UART. Max DC current per I/O: 40 mA. Misc – Reset button, LEDs Power Supply 5V via micro USB port 3.7V LiPo battery (2,500 mAh battery included in kit) Dimensions – TBD The board can be […]

$25 TinyScreen is an OLED Display for TinyDuino Arduino Compatible Board (Crowdfunding)

Back in 2012, Tiny Circuits launched a Kickstarter campaign for TinyDuino, an Arduino compatible board that’s… tiny, based on Atmel Atmega328P, and supports tiny stackable shields in a similar fashion to Microduino (launched in 2013). The campaign was successful, and the company is now back on Kickstarter with TinyScreen, an OLED display that can be stacked on top of TinyDuino to create a smartwatch, a minuscule gamepad, smart glasses, and more. TinyScreen technical specifications: 96×64 OLED display, 16-bit color depth 0.96″ (24.4mm) viewable area Software controllable backlight (OLED brightness) Power down mode Four push buttons along the sides (connected to IO pins) SPI interface for display Power Supply – 3.0V to 5.5V operation (higher voltages supported with TinyShield power regulator) Power Consumption – 20 – 45mA max supply current (depending on brightness) Dimensions – 25.8mm x 25.0mm Programming of TinyDuino can be done through a web interface for Arduino called […]

WifiDuino Arduino Compatible Wi-Fi Board Features an Optional OLED Display (Crowdfunding)

Getting Wi-Fi with Arduino can be relatively expensive, and may take a little too much space. Spark Core board greatly addressed both price ($39) and form factor issue last, but there’s another option coming to market thanks to WifiDuino a $34 board with Wi-Fi, that’s tiny and Arduino compatible. An OLED display is also available as an option, at a lower price point than MicroView board, and including Wi-Fi or not, depending on the perk. WifiDuino hardware specifications: MCU – Atmel Atmega32U4 (same as Arduino Leonardo) Display – Optional 128×64 OLED display Connectivity – Optional Wi-Fi 802.11 b/g with STA, AP and ADHOC network modes Digital I/Os – 20 Analog I/Os – 12 Other I/Os – 7x PWM, UART, I2C, SPI Power – 5V Dimensions – Duino board only without Wi-Fi nor OLED: 25.6mm x 38.8mm x 11.0mm WifiDuino support the Arduino IDE, so you can write you sketch as […]

MicroView is a Tiny Arduino Compatible Board with an OLED Display (Crowdfunding)

Last year, we’ve been presented with many small Arduino compatible boards such as MicroDuino, RFDuino, BLEDuino, Spark Core, Olimexino-Nano and more… All these boards have been own strength and connectivity options, but if you want to see what going on in your board, you’d either need to connect it to your computer, or connect some LEDs or an external display. Geek Ammo’s MicroView fixes that by providing an Arduino compatible board nicely combined with a built-in OLED display. This allows you to display stats, weather, play games, create wearable projects (watch, necklace), and all sort of other projects that may require a small display. MicroView specifications: MCU – Atmel ATmega328P @ 16 MHz with 32KB flash, 2 KB SRAM, and 1KB EEPROM Display – 64×48 OLED Display Digital I/O – 12 (of which 3 provide PWM output) Analog Input – 6 Operating Voltage: 5V Input Voltage: 3.3VDC to 16VDC, no […]
