Development Board
Building a development board is something I have wanted to do for a long time. Like many other robot builders, when I want to just work on a concept or play around with a new sensor, I don’t want to have to build a new circuit every time. So I built a development board. It comes complete with a mouthful of features so here I go…
-
5 volt, 2 amp power supply.
-
Sockets for all PIC Microcontrollers, with in-circuit programming.
-
Sockets for all Basic Stamp microcontrollers, with in-circuit programming.
-
Sockets for all Basic Atom microcontrollers, with in-circuit programming.
-
Socket for the SX-28 microcontroller, with in-circuit programming.
-
2 x 2 amp motor controllers with directional LEDS. The power can be switched so the motors run on an external battery. This can also be used as a bipolar stepper motor driver.
-
Unipolar stepper motor driver with directional LEDS.
-
Socket for a parallel LCD in 4-bit mode.
-
Socket for a serial LCD.
-
8x8 LED matrix with red and green LEDS.
-
2 x 7-segment common cathode LEDS.
-
2 x 7-segment common anode LEDS with driver chips.
-
Peizo speaker.
-
Audio amp with connector to attach an external speaker.
-
2 x Potentiometers, with the legs attached to 5 volts and ground.
-
DB-9 connector
-
8 x servo headers.
-
8 x LEDS that can be controlled independently, or through a serial to parallel shift register.
-
8 x buttons that can he read in independently, or through a parallel to serial shift register.
-
Solder-less breadboard for custom circuits.
All of the pins for the microcontrollers and the control pins for the devices run to sip headers on the side of the solder-less breadboard. Everything can simply connect to each other using a wire or two.
Next to the power input I placed a set of 8 switches. Each device that requires 5 volts is connected to one of the switches. Now no power will be wasted running a chip that you are not using.
If you have any questions don’t hesitate to ask.
