The HD-1440A analog servo from Power HD is one of the smallest servos we carry and is a great, inexpensive, tiny actuator for a small robot mechanism. Servo horns and associated hardware are included.Key specs at 6 V: 0.10 sec/60°, 11 oz-in (0.8 kg-cm), 4.4 g.

An example of hardware included with the Power HD sub-micro servo HD-1440A and the sub-micro servo 3.7g (generic). Actual hardware might vary.

This is a great general-purpose actuator for tiny mechanisms. The lead is terminated with a standard “JR”-style connector, which is Futaba-compatible. Mounting screws and an assortment of servo horns is included with this servo (hardware might vary). You can find more information about this servo under the specifications tab and in its datasheet (379k pdf).

Note that, as with most hobby servos, stalling or back-driving this servo can strip its gears.

Note: The case of this servo has changed from translucent blue to solid black (pictures of the two versions are available under the pictures tab).

Say hello to our 0.96" 160x80 Color TFT Display w/ MicroSD Card Breakout – we think it's T-F-Terrific! It's the size of your thumbnail, with glorious 160x80 pixel color. This very very small display is only 0.96" diagonal, packed with RGB pixels, for making very small high-density displays.

This lovely little display breakout is a great way to add a small, colorful and bright display to any project. Since the 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 0.96" display has 160x80 color pixels. Unlike the low cost "Nokia 6110" and similar LCD displays, which are CSTN type and thus have poor color and slow refresh, this display is a true TFT! The TFT driver (ST7735R) can display full 16-bit color using our library code.

The breakout has the TFT display soldered on (it uses a delicate flex-circuit connector) as well as a 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 color bitmaps from a FAT16/FAT32 formatted microSD card. The microSD card is not included, but you can pick one up here.

Of course, we wouldn't just leave you with a datasheet and a "good luck!" - we've written a full open source graphics library that can draw pixels, lines, rectangles, circles, text and bitmaps as well as example code and a wiring tutorial. The code is written for Arduino IDE but can be easily ported to your favorite microcontroller!

The Nokia 5110 is a basic graphic LCD screen for lots of applications. It was originally intended to be used as a cell phone screen. This one is mounted on an easy to solder PCB.

It uses the PCD8544 controller, which is the same used in the Nokia 3310 LCD. The PCD8544 is a low power CMOS LCD controller/driver, designed to drive a graphic display of 48 rows and 84 columns. All necessary functions for the display are provided in a single chip, including on-chip generation of LCD supply and bias voltages, resulting in a minimum of external components and low power consumption. The PCD8544 interfaces to microcontrollers through a serial bus interface.

Note: There may be small blemishes on these screens as they are surplus.

Note: Your screen may or may not have a diode on the PCB. It does not affect performance and will vary depending on our shipment.

45x45mm

This is the latest evolution of our serial LCD. Included on a single board is a 16x2 LCD and an embedded circuit based around a PIC 16F88. The on-board PIC takes a TTL serial input and prints the characters it receives onto the LCD. The installed firmware also allows for a number of special commands so you can clear the screen, adjust the backlight brightness, turn the display on/off, and more.

Communication with SerLCD requires 5V TTL serial at a default baud rate of 9600bps (8-N-1). You can adjust the baud to any standard rate between 2400 and 38400bps. The power (VDD), ground (GND) and RX pins are all broken out to both a 0.1" pitch header as well as a 3-pin JST connector.

SerLCD has the ability to dim the backlight to conserve power if needed. There is also a potentiometer on the back of the display to adjust the contrast.

Features

Embedded PIC 16F88 utilizes onboard UART for greater communication accuracy

Adjustable baud rates of 2400, 4800, 9600 (default), 14400, 19200 and 38400

Operational Backspace

Greater processing speed at 10MHz

Incoming buffer stores up to 80 characters

Backlight transistor can handle up to 1A

Pulse width modulation of backlight allows direct control of backlight brightness and current consumption

All surface mount design allows a backpack that is half the size of the original

Faster boot-up time

Boot-up display can be turned on/off via firmware

User definable splash screen* PCB: 103x36mm

LCD: 71.4x26.4mm

The SparkFun Micro OLED Breakout Board breaks out a small monochrome, blue-on-black OLED. It’s “micro”, but it still packs a punch – the OLED display is crisp, and you can fit a deceivingly large amount of graphics on there. This breakout is perfect for adding graphics to your next Arduino project, displaying diagnostic information without resorting to serial output, and teaching a little game theory while creating a fun, Arduino-based video game. Most important of all, though, is the Micro OLED is easy to control over either an SPI or I2C interface.

You may be asking yourself, “Why does this board look so familiar?” Yes, this is essentially a MicroView without the Arduino portion. We understand that sometimes you just need a breakout, an open door for you to explore the possibilities of a super small OLED screen. Speaking of, the screen on this breakout is only 64 pixels wide and 48 pixels tall, measuring 0.66" across.

In total, the Micro OLED Breakout provides access to 16 of the OLED’s pins. Fortunately, though, you’ll only need about half of them to make the display work. The top row of pins (GND-CS) breaks out everything you’d need to interface with the OLED over an SPI or I2C interface. The pins on the bottom (D7-vB) are mostly only used if you need to control the display over a parallel interface. This board operates at 3.3V with a current of 10mA (20mA max).

The MicroView is the first chip-sized Arduino compatible module that lets you see what your Arduino is thinking using a built-in OLED display. With the on-board 64x48 pixel OLED, you can use the MicroView to display sensor data, emails, pin status, and more. It also fits nicely into a breadboard to make prototyping easy. The MicroView also has a full-featured Arduino library to make programming the module easy.

In the heart of MicroView there is ATMEL’s ATmega328P, 5V & 3.3V LDO and a 64x48 pixel OLED display, together with other passive components that allow the MicroView to operate without any external components other than a power supply. Additionally, the MicroView is 100% code compatible with Arduino Uno (ATmega328P version), meaning the code that runs on an Arduino Uno will also be able to run on the MicroView if the IO pins used in the code are externally exposed on the MicroView.

Note: The MicroView programmer is sold separately. Check the recommended products below. Also, unlike the Kickstarter campaign, this does not come with the breadboard and USB cable. You only get the bare module.

The MicroView is the first chip-sized Arduino compatible module that lets you see what your Arduino is thinking using a built-in OLED display. This USB programmer connects directly to the MicroView and lets you not only program the module, but use it to interface with your computer, Rapsberry Pi, or other USB device. The programmer has both male and female headers which allow it to be plugged into a MicroView module and a breadboard at the same time, making prototyping quick and easy.
