If you want to easily connect a large, 7 segment display to your project, this product is for you.

• Ground + 3 data pins + PWM dimming signal (optional) connected via a standart 0.1" header or an IDC 6 pin connector
• DC 5525 jack for power (10 to 15 V)
• Linear CC driver (no multiplexing - so no flicker on camera and longer life of LEDs)
• Multiple PCBs can be easily connected (chained) together
• Convenient mounting holes
• 3.3 or 5 V version available
• Display: 2.3" character height, yellow-green color (actually, I have a listing just for the bare displays)

Firmware

The driver behaves like a classical shift register - a really easily portable example can be found here.

Product options

Please specify the number of input (these have IDC, power regulator and DC jack) and normal modules. Each module has two digits.

Notes

• Multiple modules snap together firmly, but since the displays are relatively heavy, you must provide external support, otherwise it could break out the connectors.
• Driver IC is STP16CPC26.
• Please, watch out for polarities and follow the usual connection and ESD-protection rules! Especially on the IDC connector - pin functions are silkscreened on the back of the PCB, with pin 1 being on the bottom right - see the picture for reference.
• There is a 10kOhm pulldown on the OE line. If you are building something low power, you may wish to desolder it and instead rely purely on driving it with a MCU.
• One module can draw up to 16 * 20 mA = 320 mA of current - make sure your power supply can handle that!
