Another box of new boards arrived from DirtyPCBs.com today.
In the box where 4, yes 4 sets of PCB’s.
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 I 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 on my Tindie store in the next few days.

MiniPiio SimpleIO is just that, a add-on board with simple inputs and outputs. It features 8x LED’s and 8x tactile switches. The Pi’s GPIO4/17/18/22/23/24/25/27 are each connected to an LED and switch.
You have 8x signals you can mix and match with whatever combination of LED’s or switches your design needs. So if you need more indicators you could have say 6x LED’s and 2x switch inputs and like wise, if you need more inputs than outputs you could have 5x switch inputs and 3x LED outputs.
You can find them at our store on Tindie.
Note: LED and Switches sharing the same GPIO so are not designed to used simultaneously.

Eh? Why another prototyping board? Isn’t the CM I/O a prototyping board already?
Yes, it is. And the CMIO ProtoBoard is a prototyping board for you to build circuits directly on with can be used with the CM I/O board and Compute Module.
Same as blinking an LED is the first code you write for a new embedded system, designing a prototyping board is often the first thing I do with every new system I work with.
Why, I hear you ask?
- I want some thing I can quickly build permanent circuits with, so the days of loose wires spoiling my days are far behind.
- I want some thing that is cheap and cost effective. I want to experiment with different circuit designs, without worrying if I’ve wasting money every time I start a something new.
- I want some thing that when its built looks decent and not a heap of wire
Some of the dimensions and connector positions I’ve had to guess at but here’s a quick layout of what I’ve done so far:

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.

Exciting times are here.
We received our first batch of PCB’s from our manufacturer yesterday.
In the package were 5 sets of blank PCB’s for the RPi_ProtoBoard and the first of the MiniPiio boards: MiniPiio_RS232, MiniPiio_DIO16, MiniPiio_ULN2803 and MiniPiio_ProtoBoard.
Even though it was late at night we couldn’t resisting building a couple of the boards. So we built the RPi_Protoboard:
and the MiniPiio_ProtoBoard:
hers a picture of both boards:
We’ll get the rest of the boards assembled over the weekend and post them here.
