DIGIO-128 Board Adds 128 GPIOs to Your Development Board

If you run out of GPIOs on your board, the easy way is to add an I2C GPIO expander, but those are normally limited to 8 or 16-channels, so Land Boards decided to create a board with 8 IO expanders making it a 128 channel IO expander that works on Raspberry Pi, BeagleBone Black, Arduino, and basically any boards with an I2C hardware or software implementation. DIGIO-128 board specifications: 8x Microchip MCP23017 16-bit I/O expander for up to 128 GPIOs Communication Interface – I2C host interface with 100/400 KHZ operation; 4-pin host interface connector (Ground, Power, Clock, Data) 8x 20-pin 2.54mm pitch connectors with 16 I/Os, 2x VCC, and 2 ground 2x 4-pin interrupt connectors Data Storage – Microchip 24LC024 2K EEPROM with board info. 3.3V or 5V operation Dimensions – 95 x 95 mm You can find out to use the board in the Wiki for code for Raspberry […]

Getting Started with Wemos D1 mini ESP8266 Board, DHT & Relay Shields

Wemos D1 mini is an ESP8266 board that’s interesting thanks to its size, its low price ($4), micro USB power, its shields, and a documentation that looks fairly good. The board can be programmed with Arduino or Lua, and supports both serial and OTA programming. I’ve decided to give it a try and bought the board together with two temperature shields, a relay shield, and micro SD shield. I got all for $ 14.00 from Wemos Aliexpress shop, and it took about one month for delivery. I can also see they’ve recently released a new OLED shield selling for about $5. All shields were shipped inside their own anti-static bags. The pins are clearly marked on both side of the board and the shields. One side of the board features ESP8266 module. and the other side has CH340 serial to USB chip, and the reset button. The provided headers make […]

Cleo35 Touchscreen Display for Arduino UNO Comes with Tutorials and Example Projects (Crowdfunding)

There are already various options to add a (touscheen) display to Arduino board with software support including TFTLibrary for Arduino, and recently I tried Nextion serial touchscreen displays that are supported by a WYSIWYG editor, but the latter is only supported in Windows and not exactly user-friendly, and I found the few provided tutorials would only work with a specific resolution incompatible with the displays I had been sent. So I gave up on the idea of interfacing the display with Arduino or ESP8266 as it would be too time-consuming. FTDI CleO project might be faster and easier to get started, as their CleO35 touchscreen display for Arduino UNO will come with a 20 chapter tutorial covering over 80 topics, and 20 projects to get started. Some of the key features and specs of Cleo35 display include: MCU – FTDI FT903 32-bit FT32 core @ 100MHz with 256kB on-chip Flash […]

$4 Wemos D1 mini ESP8266 Board Supports Shields with a Temperature Sensor, a Button, a Relay, or a micro SD slot

Wemos D1 board, a $9 ESP8266 board in Arduino UNO form factor, now has a little brother with Wemos D1 mini. The board looks somewhat similar to NodeMCU with breadboard friendly I/Os on the sides and a micro USB port for power and programming, but what could make it more interesting, beside the $4 price tag, is that the company also developed several shields (aka add-on boards). Wemos D1 mini specifications: WiFi 802.11 b/g/n module based on ESP8266EX with 4MB flash Expansion – Through holes with 11x digital input/output pins (3.3V) supporting interrupt/PWM/I2C/one-wire (except D0) 1x analog input (3.3V max input) Reset and power signals (5V, 3.3V, GND) USB – micro USB port Misc – Reset button Power – 5V via micro USB or 5V pin Dimensions – 34.2 x 25.6 mm Weight – 10 grams The board is said to be compatible with Arduino IDE and NodeMCU firmware.
