New board – MiniPIIO Breakout!

March 21, 2014

MiniPIIO Breakout! is our newest add-on board for the Raspberry Pi.

It breaks out (hence its name) all the Pi’s expansion I/O into four neat little groups.

UART is broken out into a 6-Way and 4-way pin header. The 6-Way is FTDI USB Cable compatable.

SPI is broken out into two 6-way headers, each with it’s own SPI chip select.

I2C is borken out into two 4-way headers.

GPIO is broken out into two 10-way headers. GPIO4/17/18/22/23/24/25/27 and 3.3V and 0V.

RPi-X ELab101 – mini electronics lab

March 7, 2014

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

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.

RPi-X SensoRPi – 2nd prototype with different connectors

February 10, 2014

Here’s some photos of the second RPi-X SensoRPi which uses 2.1mm DC barrel style connectors instead of the 4mm connectors the first prototype used.


Here’s a picture of of the SensoRPi board and the 2.1mm DC connectors


And here’s a picture of the 2.1mm DC barrel to crocodile/alligator clips.


RPi-X SensoRPi – more photos & update

February 9, 2014

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 SensoRPi – first photos

February 3, 2014

Here’s some photos of the first partially built boards:



RPi-X SensoRPi

January 30, 2014

This is the first of my RPi eXperimenter boards – SensoRPi.

It’s designed to interface your Pi to on-board sensors for light and temperature and to other external analogue sensors via its connectors.

2x potentiometers, 4x LED’s and 4x tactile switches and a buzzer provide a simple user interface.

In addition an I2C interface is included for connecting to digital sensors as well as 3x digital input/output interfaces.

I’ve been testing the MiniPiio AIN4 board the last couple of weeks and I’m pleased to say it works well.


Here’s a picture of it mounted on the Pi.



New MiniPiio SimpleIO and RS485

March 24, 2013

We’ve got a couple of new MiniPiio boards in the works.

The first MiniPiio is SimpleIO which is 8x LED’s and 8x Tactile Switches connected to the GPIO signals. This is currently being manufactured, so we’ll let you know how it goes.


The second MiniPiio is a serial RS485 board. It’s the one I’ve been asked a lot for. The layout is finished and its going out for manufacture next week.
