Description:

Using the analog I/O - module RevPi AIO your RevPi base module can be expanded by 4 analog inputs, 2 analog outputs and 2 RTD input channels. This expansion module is connected to your base module by the means of the overhead PiBridge plug. Inputs, RTD inputs and outputs are galvanically isolated to each other. Differential inputs eliminate ground loops.

Analog input range/options: +/- 10 V, 0 – 10 V, 0 – 5 V, +/- 5 V, 0 – 20 mA, 0 – 24 mA, 4 – 20 mA, +/- 25 mA

Analog outputs range/options: 0 – 5 V, 0 – 10 V, +/- 5 V, +/- 10 V, 0 – 5,5 V, 0 – 11 V, +/- 5,5 V, +/- 11 V, 4 – 20 mA, 0 – 20 mA, 0 – 24 mA

The 2 RTD inputs enable temperatures to be measured with high precision from -165°C to +600°C in steps of 0.5°C using common RTDs sensors like Pt100/Pt1000 probes. The probes can be connected directly to the module with 2, 3 or 4 cables.

Just like the digital IO modules, RevPi AIO is protected against disturbances according to EN61131-2 and can be operated between -40 and +50°C ambient temperature and up to 80% relative humidity. It is also protected against static discharges, burst and surge impulses in accordance with EN61131-2 requirements.

The required PiPridge Plug (Item No.: 100204) and a set of 14-pole PCB female connectors (Item No.: 200030) are already included in the scope of delivery of this expansion module.

Power-up your TV with Picade Console! It's a compact, Raspberry Pi-powered retro games machine with authentic arcade controls that plugs right into your TV, monitor, or other HDMI display.

Picade Console is fight stick-style arcade console that riffs off our new Picade with the same retro feel, same joystick and buttons, dedicated power button, and driven by the same powerful combo of the Raspberry Pi and Picade X HAT. It's beautifully packaged, comes with stickers and a neon-infused A3 Picade Console poster, and full assembly instructions.

It comes in kit form and takes an hour or two to build. The enclosure is made from powder-coated MDF and acrylic, giving it an authentic arcade look and feel. All you'll need to add is a Raspberry Pi, power supply, HDMI cable, and micro-SD card.

*TV not included! Using a CRT TV requires additional adaptors.

Features

• Black, powder-coated panels
• Acrylic console with retro artwork
• Push-fit arcade buttons
• Joystick with black ball top
• Speaker (3W, 4Ω, 2.5" driver)
• Easy access with removable back panel
• Dedicated illuminated power button
• Grippy rubber feet
• Dimensions (assembled): 245x120x140mm

Picade X HAT features

• Easy DuPont connectors for buttons and joystick
• Push-fit speaker terminals
• I2S audio DAC with 3W amplifier (mono)
• Power management, power switch pins, and power button
• 4-way joystick inputs
• 6 player buttons
• 4 utility buttons
• Metal standoffs to hold your Picade X HAT securely

Extras

• Picade Console poster / assembly instructions
• Picade stickers

What's new?

Picade Console is more compact and easier to build, but has a bunch of new features liked a dedicated power button, better cable routing out the back of the console with a panel-mount micro-USB connector for power, and slick new artwork.

The new buttons in Picade are lower profile, and the new joystick has a single connector rather than the eight spade connectors on our previous Picade joystick.

Picade X HAT is all-new and packed full of useful features. We've moved from more fiddly screw terminals to simple DuPont connectors that just push in, and the speaker terminals are the same easy push-fit connectors that we use on pHAT BEAT.

There's dedicated power management on-board Picade X HAT; just plug your micro-USB power supply into the HAT and it'll power your Pi through its pins. The power button connected to the HAT means that once your Pi is safely shutdown, the power will be cut completely to the Pi. A simple press of the power button will boot your Picade Console up again.

Software setup

We recommend the RetroPie operating system for your Picade. You can download it from the RetroPie website and then burn it to a micro-SD card with Imager.

Connect a USB keyboard to your Pi, and connect to Wi-Fi in the RetroPie menu. Press F4 to exit to the terminal and then type curl https://get.pimoroni.com/picadehat | bash to run the Picade HAT installer.

Reboot your Pi, if it doesn't prompt you to. Press the "Alt" key on your keyboard and then select "Configure input" to configure your Picade Console's controls. You'll find that the sound and power button should both be working now too!

Explorer pHAT is the perfect prototyping side-kick for your Raspberry Pi!

A more diminutive version of our popular Explorer Hat Pro, it's cheaper and designed to fit perfectly on a Raspberry Pi Zero!

We've added a heap of useful input and output options that will take your projects to the next level. Great for driving motors, using analog sensors, and interfacing with 5V systems (like Arduino).

Perfect for building a tiny robot, or use it to prototype all sorts of circuits with its LEDs, analog dials, and temperature sensor.

Features

• Four buffered 5V tolerant inputs (perfect for Arduino compatibility)
• Four powered 5V outputs (up to 500mA total across all four channels)
• Four analog inputs
• Two H-bridge motor drivers (up to 200mA per channel; soft PWM control)
• Compatible with Raspberry Pi 3, 2, B , A , and Zero
• Python library
• Female headers require soldering

Software

Explorer pHAT uses the same easy-to-use Python library as Explorer HAT Pro, that includes a bunch of examples to demonstrate Explorer pHAT's functions.

Notes

The inputs use a 5-channel buffer that will accept anything from 2V-5V as logic high.

This testing wire with alligator clips will help transmit DC current to other multi-meters or other usage.
Made from copper wire and well-made PVC.
It can pass 3-5A(max) current during your testing work.
High performance, lower resistivity and durable, fast and stable, high-speed output current

Specifications

• Colour: Red and Black (V and V-)
• Power: 5V
• Working current: 3-5A
• Lines size: 2x18AWG
• Cable Length: 332mm

Is this not the cutest little display for the Raspberry Pi? It features a 2.8" display with 320x240 16-bit color pixels and a capacitive touch overlay. That's right, instead of a resistive touchscreen, which requires a fingernail or stylus, you can now use a fingerpad.

The screen looks much nicer, with a black bezel and glass overlay.

This updated design fits perfectly onto the Pi Zero, Pi 3, Pi 2 or Model A , B ! (Any Pi with a 2x20 connector) Not for use with an old Pi 1 with 2x13 connector. This version also has all 40 pins GPIO pins brought out so you can connect a 40-pin GPIO cable underneath.

The display and touchscreen uses the hardware I2C Pins (SDA & SCL), SPI pins (SCK, MOSI, MISO, CE0) as well as GPIO #25 and #24. All other GPIO are unused and you can still share the I2C pins with sensors, LED drivers, etc. Since we had a tiny bit of space, there's 4 slim tactile switches wired to four GPIOs, that you can use if you want to make a basic user interface. For example, you can use one as a power on/off button.

Use it for console access or easily pop up X11 onto the PiTFT for a mini monitor, although its rather small at 320x240. Instead, we recommend using PyGame or other SDL-drawing programs to write onto the frame buffer.

Raspberry Pi computer and enclosure not included! As of July 22nd, 2015 this display comes fully assembled with tactile switches too
