Four new Raspberry Pi add-on boards

May 13th, 2014 No comments

Another box of new boards arrived today.

In the box where 4, yes 4 sets of PCB’s.

RPi_PIAC_and_others_small
In the photo, the big PCB at the back is RPi-X PIAC. On the photo front row, on the left is MiniPiio LED Breakout, in the centre is MiniPiio BOP4 and to the right is MiniPiio PWM16

RPi-X PIAC is our latest RPi-X experimenter board. The acronym IAC is commonly used to describe an industrial automation and control system and adding a P in this case makes it a Pi Industrial Automation and Control :-)

PIAC has 4x SPCO Relays rated at 2A, 4x opto-isolated digital inputs, 4x 0-10V Analogue inputs and finally a RS485 communications port. So with the RPi-X PIAC you can learn about industrial control or perhaps use it for your own small industrial project.

MiniPiio LED Breakout uses the popular MAX7219 8-digit (64x LED) LED display driver chip to breakout all 64 LED outputs to 8 rows of pin headers. From these pin headers you can plug in individual LED’s to make whatever LED display layout you want. It’s a shame its not Christmas as we think it would make a great blinky LED Christmas tree :-)

MiniPiio BOP4 or Board of Pots (or should that be “Bored of Pots”) has 4 potentiometers (3x rotary and 1x slider) and connects them to a 4-ch MAX3004 ADC. I think it will a great physical user interface. It’ll probably make a great companion to the LED/Switch MiniPiio SimpleIO we showed off a few months back. Of all the new boards I think this is my favourite :-)

The final new PCB, is MiniPiio PWM16. I think its name gives it away. It’s a hardware based 16-channel PWM add-on board using the popular PCA9685.

As always you’ll find them in our Tindie store in the next few days.

RPi-X SensoRPi – more photos & update

March 9th, 2014 No comments

We’ve got a couple of more photos to show you. This time the RPi-X SesnoRPi is mounted into a case.

RPi-X_SensoRPi+PiBow2 RPi-X_SensoRPi+PiBow1

Mounted into a case the SensoRpi is extremely ridged.

We’ve continued testing and the electronics are all confirmed working. So far we’ve tested it using Python and RPi.GPIO, next we’ll be testing it using Scratch with the GPIO extensions from Simon at Cymplecy.

Once we completed our Scratch software testing will be looking to extend our testing to Gordon’s wiringPi and RPIO

RPi-X ELab101 – mini electronics lab

March 7th, 2014 No comments

RPi-X ELab101 is the second of our RPi-eXperimeter boards.

RPi-X_Elab101_small
RPi-X ELab101 is a mini electronics lab for the Pi.

It is dominated by a 170-pin bread boarding area for prototyping and construction your circuits on. Next to this, there are 3x tactile switches, 3x LED’s, 2x potentiometers and a buzzer circuit which make up the input and output devices. These are connected to female headers allowing them to be quickly interfaced with the Pi’s GPIO’s using simple male-male jumper wires.

For analogue measurements, a 4-channel 0V to 10V, 10-bit ADC is included and it’s inputs are also available via a female header connector.

Finally, all the signals from the Pi’s expansion header are brought out to female headers, giving access to all the Pi’s expansion signals, including the GPIO’s, SPI, I2C, UART and PWM.
