60 LED (6 x 10) cost-effective matrix display based on STP16CPC26 with Bluetooth Low Energy and Android application

STEVAL-LLL005V1

Overview

The STP16CPC26 low voltage 16-bit constant current LED sink driver on the STEVAL-LLL005V1 evaluation board ensures a cost effective 6x10 LED matrix with individual LED control.

The LED driver evaluation board includes a jumper to select between powering the board through a standard DC jack input or a USB Type-C connector, as well as two control switches.
An Android app is also available for enhanced user experience and control.
The SPBTLE-RF very low power module for Bluetooth Smart v4.1 allows communication with the board via your smartphone.
The STM32F030 mainstream ARM Cortex-M0 Value line MCU with 64 Kbytes of Flash, 48 MHz CPU manages driving and transmission of data over BLE.

Main features

Cost effective 16-bit LED driving scheme
Driver for 6x10 LED matrix with individual LED control and row-wise scanning
USB Type-C and DC jack connector for DC input power
Bluetooth Smart connectivity and Android application for hassle free demonstration
Connector for stacking multiple LED drivers in daisy chain configuration
Preconfigured demos (selected through on-board switches):
- with brightness control
- with speed control
