The Joey makes it easy for your Raspberry Pi projects to display numbers such as readings, a counter, or a clock.
It is a compact 4 digit LED display board which sits off to the side of the GPIO header so you can use other expansion boards at the same time - the Joey display remains visible, even with a HAT mounted on top of your Pi!
The Joey is simple to use - we provide a comprehensive Python library, sample applications and, of course, full documentation.
Why would I want one?
Does your project need to show the time? Or readings from the real world, such as temperature?
Do you have an add-on, such as the prototyping board shown below, that would get in the way of other displays?
The Joey is the easiest way to display numbers on your Raspberry Pi - inexpensive and no screen required.
What does it do?
The Joey shows numbers (up to four digits) on a small display board. It can even display short text messages.
Your Raspberry Pi projects can easily display their status or current readings.
Joey connects over the I2C bus so all the GPIO pins are still available (the I2C bus is designed to be shared) and other expansion boards can plug over the top of the Joey.
Also, there are three inputs that you can use to add extra functionality to your projects. Change modes, read configuration options, alter settings - our Python library makes it easy. They're supplied as jumpers, but you could connect switches, such as pushbuttons, to them if you wish.
See the video from our successful Kickstarter campaign for a more visual overview:
- 4 x 7-segment LED display
- Includes decimal points, a ':' (for clock) and extra dot (degrees symbol)
- 3 x user-readable inputs (jumpers)
- Connects via I2C - no dedicated GPIOs used
- I2C address can be changed if necessary
(to avoid conflict with any other I2C devices)
- mounting hole to allow HAT standoffs to pass through
- Comprehensive Python support library, example code and documentation provided
