1.38” Round TFT LCD
The LCD-220RD available from 4D Systems is a unique 1.38” round LCD intelligent display module powered
by their DIABLO16 graphics processor.
The uLCD-220RD is designed for applications such
as gauges and instruments, or for special applications
such as robotics.
Driving the display and peripherals is the DIABLO16
processor — a very capable and powerful chip which
enables stand-alone functionality that is programmed
using the 4D Systems Workshop 4 IDE software. The
Workshop IDE enables graphic solutions to be constructed
rapidly and with ease due to its design being solely for
4D’s graphics processors.
The display module has an array of features including
PWM, micro-SD memory storage, general-purpose I/O
including analog inputs, multiple TTL serial, I2C, and SPI
channels, quadrature input, pulse output, and multiple
millisecond resolution timers, among other features.
The new 32 pitch/24 tooth Actobotics bevel gears from ServoCity allow users to build right angle drives inside or
outside of channel. These bevels work well for building
differentials or any application where you need to transfer
rotational motion 90 degrees. Now offering both metric
( 4 mm - 6 mm) and SAE (1/4") bore diameters, these gears
are appropriate for all kinds of applications. Simply slide the
gear on the shaft and tighten the set screw. They are
manufactured from hardened brass gear stock for extreme
durability and strength. Prices start at $5.99/each.
Redesigned Linear Servos
Anewly redesigned heavy duty linear servo is also now available from ServoCity. While a linear servo may
appear similar to a linear actuator, it runs on a completely
different signal. The linear servo can plug into just about
any servo controller — wired or wireless. The advanced
internal circuit board reads the PWM signal received from
the servo controller and will precisely control the position
of the linear servo. A PID algorithm is used in order to
minimize settling time and overshoot.
The 24 kHz PWM output frequency creates very
smooth movements without any PWM noise. The internal
board is nearly bullet-proof as it's protected against reverse
polarity, over-current, and over-temperature. There is a built-in circuit (BEC) that supplies power (5V, 500 mA) to your
servo controller so that everything can be powered off a
single power source. The aluminum construction ensures
tremendous durability and reliability. These linear servos are
offered in stroke lengths from two inches up to 12 inches;
the extension shaft is .785" in diameter. Mounting points
are 5/16" diameter and are directly compatible with various
ServoCity mounting brackets. Prices start at $299.99/each.
