Out of stock2.8 inch SPI Touch Screen Module TFT Interface 240*320
[LED/LCD Display Module] This TFT display is big (2.8″ diagonal) bright and colorful! 240×320 pixels with individual RGB pixel control, this has way more resolution than a black and white 128×64 display. As a bonus, this display has a resistive touchscreen attached to it already, so you can detect finger presses anywhere on the screen. This display has a controller built into it with RAM buffering so that almost no work is done by the microcontroller. The display can be used in two modes: 8-bit and SPI. For 8-bit mode, you’ll need 8 digital data lines and 4 or 5 digital control lines to read and write to the display (12 lines total). SPI mode requires only 5 pins total (SPI data in, data out, clock, select, and d/c) but is slower than the 8-bit mode. In addition, 4 pins are required for the touchscreen (2 digital, 2 analogs). This 2.8 inch SPI Touch Screen Module is wrapped up into an easy-to-use breakout board, with SPI connections on one end and 8-bit on the other. Both are 3-5V compliant with high-speed level shifters so you can use with any microcontroller. If you’re going with SPI mode, you can also take advantage of the onboard MicroSD card socket to display images. Stock version: 1.1V For more displays click below, LED/LCD Display Features : It shows the color depth of 262K/65K. Need at least 4 IOs from your MCU The display has a wide viewing angle. Big display with good resolution.

1.8 Inch TFT LCD Module 128 x 160 with SPI
[LED/LCD Display Module] Since the 1.8 Inch TFT LCD Module display uses 4-wire SPI to communicate and has its own pixel-addressable frame buffer, it can be used with every kind of microcontroller. Even a very small one with low memory and few pins available! The 1.8″ display has 128×160 colour pixels. Unlike the low cost “Nokia 6110” and similar LCD displays, which are CSTN type and thus have poor colour and slow refresh, this display is a true TFT! The TFT driver (ST7735R) can display full 18-bit colour (262,144 shades!). And the LCD will always come with the same driver chip so there are no worries that your code will not work from one to the other. The breakout has the TFT display soldered on (it uses a delicate flex-circuit connector) as well as an ultra-low-dropout 3.3V regulator and a 3/5V level shifter so you can use it with 3.3V or 5V power and logic. We also had a little space so we placed a microSD card holder so you can easily load full-colour bitmaps from a FAT16/FAT32 formatted microSD card. For more displays click below, LED/LCD Display Features : 1.8-inch serial SPI colour display module Support analogue SPI and hardware SPI The LCD has a wide viewing angle, the contrast is also very suitable. Good quality display. Package includes: 1 x 1.8 Inch TFT LCD Module 128 x 160 with 4 IO
Out of stockPS2 Joystick Module Breakout Sensor
[Breakout Board] Dual Axis XY Joystick Module This is JoyStick Module PS2 Breakout Sensor very similar to the ‘analog’ joysticks on PS2 (PlayStation 2) controllers. Directional movements are simply two potentiometers – one for each axis. Pots are ~10k each. This joystick also has a select button that is actuated when the joystick is press down. With the help of this Joystick Module, you can measure position coordinates on the X and Y axis by moving the “hat”. It also contains a switch that is press-able by pushing the “hat”.It also contains a switch that is press-able by pushing the “hat” down. Similar to the XBOX controller. The X and Y axes are two 10k potentiometers which control 2D movement by generating analog signals. When the module is in working mode, it will output two analog values, representing two directions. This module uses the 5V power supply, and value, when reading through analog input, would be about 2.5V, a value will increase with joystick movement and will go up till maximum 5V; the value will decrease when the joystick is moved in other direction till 0V. Applications: 1. As square wave signal generator which generates a square wave signal 2. To provide a signal to the stepping motor driver 3. Adjustable pulse generation for chip use 4. Produce variable pulse signal, the control-related circuit (PWM dimming, speed) Module Description: Frequency is divided into three ranges: 1. XXX (no decimal point): the smallest unit is 1Hz, the range 1Hz-999Hz 2. XX.X (decimal point in ten): The minimum unit is 0.1Khz; the range of 0.1KHz-99.9KHz 3. X.X.X.(there is three decimal point): the smallest unit is 1Khz; the range 1KHz-150KHz Frequency Display Example: 1. ”100″ indicates that the PWM output pulse of 100Hz 2. ”54.1″ indicates that the PWM output pulse of 54.1KHz 3. ”1.2.4.” Indicates that the PWM pulse output 124KHz 4. Duty Cycle in the range:0 to 100 5. Three frequencies duty cycle is the same, all the parameters are non-volatile Features: 2.54mm pin interface leads Long service life and stable performance Standard interface and electronic building blocks Widely use in Arduino DIY projects Cross rocker as a two-way 10K resistor, with the rocker in a different direction.
