2.2″ TFT LCD shield for Arduino with microSD and I/O sockets

Posted on by Stanley

Here comes a brand new TFT LCD shield for Arduino. It features:

  • 2.2″ TFT LCD screen of 320×240@16bpp
  • ILI9341 controller (SPI)
  • I2C socket (SDA, SCL, VCC, GND)
  • UART socket (Rx, Tx, VCC, GND)
  • Analog socket (A2, A3, VCC, GND)
  • MicroSD socket (supporting up to 32GB SDHC)
  • Push button (D8)
  • Reset button
  • Compatible with Arduino UNO R3 and Bluno

The screen is driven by SPI with fast rendering speed. It is supported by MultiLCD library which provides easy API for displaying characters/digits of various size and drawing bitmaps. It can also be used with UTFT  library.

This product can be order from Freematics Hardware Store.

Arduino OBD-II data logger kit

Posted on by Stanley

After working out and merchandising the Arduino OBD-II adapter, I was thinking of putting up some kits based on the adapter with which people can start playing Arduino with cars more easily. A useful application as my initial approach is a OBD-II data logger device which reads out sensor data from vehicle and records the data on mass storage (e.g. SD card). Besides data logging, it better also displays some realtime data and states on a screen. The logged data also needs something to illustrate, possibly into a chart. All these thoughts brought up the Arduino OBD-II data logger kit and this website.

Serial 8×8 RGB LED Matrix Module for Arduino

Posted on by Stanley

The RGB LED matrix module is driven with serial data interface. It can be attached to any devices including Arduino via I2C and works as a I2C slave device, or via serial UART (can be attached to PC via a USB-TTL adapter). The module has 5×8 character font built in as well as 3×5 and 3×7 digit font, so that numbers and letters can be displayed in color easily. The module is powered by 5V input and has a 6-pin connector providing SDA, SCL, GND, VCC, RxD, TxD breakout.

Arduino OBD-II Kit available for order

Posted on by Stanley

After many researches and attempts to connect an Arduino with my car through the OBD-II port and having some successful works, I’ve finally made a kit which enables those who want to playing with Arduino and their cars to jump start quickly.

The Arduino OBD-II Kit consists of a OBD-II UART adapter based on a ELM327 compatible chip which provides an OBD-II to UART data bridge, and a dedicated open-source library for Arduino 1.0. The adapter outputs UART serial data and regulated 5V power supply sufficent for powering Arduino and some attached devices. The adapter can be used with any embedded system in addition to Arduino platform.
