This is quite possibly one of the best keyboards to consider buying if you are a developer, especially on the Mac platform, and love the feel of a tactile keyboard. Point worth noting is that for ergonomics, you might want to consider buying a wrist pad as the keyboard is quite high. It can connect to 3 devices at a time using the fn+<1,2,3> key combination, and can also alternate the RGB backlight patterns using a similar fn+ combination. The build quality is extremely impressive and sturdy as well, and fits in aesthetically with most Mac setups.
What it is?
The Graphic LCD (GLCD) is 2.4″ diagonal LCD TFT Touch Panel display.
The HiLetgo GLCD worked at expected when delivered.
The are demonstrations on Anobium’s Great Cow BASIC GitHub – easy to use.
The packaging was a solid carboard box with the GLCD sealed in an anti-static bag. The required stylis and the USB cable was supplied. The GLCD fitted without issue to the HiLego UNO board (other UNO boards were tested and the GLCD fitter these also).
The HiLetgo GLCD is a bright, 4 white-LED backlight color display that used an 8 bit digital interface, plus 4 control lines. These is laid out on the UNO shield.
The UNO uses digital pins 5-9 and analog 0-4. That means you can use the other digital and analogs. Pin 12 is available if not using the micro SD 5V compatible, use with 3.3V or 5V logic
The shield is for an Arduino UNO R3 or a MEGA2560.
My Rating
Excellent product. Fast and easy to use. Cost effective and the best GLCD ILI9341 shield tested.
Technical Details
The ILI9341 is a 262,144-color single-chip SOC driver for a-TFT liquid crystal display with resolution of 240RGBx320 dots, comprising a 720-channel source driver, a 320-channel gate driver, 172,800 bytes GRAM for graphic display data of 240RGBx320 dots, and power supply circuit.
ILI9341 supports parallel 8 bit data bus interface. The moving picture area can be specified in internal GRAM by window address function. The specified window area can be updated selectively, so that moving picture can be displayed simultaneously independent of still picture area.
ILI9341 can operate with 1.65V ~ 3.3V I/O interface voltage and an incorporated voltage follower circuit to generate voltage levels for driving an LCD. ILI9341 supports full color, 8-color display mode and sleep mode for precise power control by software and these features make the ILI9341 an ideal LCD driver for medium or small size portable products such as digital cellular phones, smart phone, MP3 and PMP where long battery life is a major concern.
This is a really good product and I can highly recommend it. Earlier this year I was suffering with bad neck and shoulder problems and paying regular (costly) visits to my osteopath. He advised that something must be wrong with my posture whilst working in front of my computer, and suggested that I either tried working standing up, or looked for a stand to raise the computer to a higher position. I opted for the stand, bought one of these and instantly cured my neck and shoulder problems. The stand gives a useful void beneath for all my desk clutter, looks great, and it makes me sit in a much more upright and comfortable position. I am so pleased with it, that I ordered my father one too. It is well made, comes well packaged and has improved my/our quality of life no end. Many thanks for designing and supplying a great product. Highly recommended!
I cannot fault either the service or the product and will definitely use again.
Worked straight from the anti-static bag. All the functions work (voltage regulators, power outputs etc) but the crystal is labelled as 12Mhz not 16! I don’t have adequate test gear to check whether the board runs slower than normal or if the on board chips run at a fraction of the crystal clock(?) the photo shows 2 crystals my device has only 1. When all is said and done I needed a backup to cover my blow-ups and this does a fine job at a ridiculously low price.
