LP5860T Evaluation Module
Description
The LP5860T Evaluation Module showcases all the
features of the LP5860T LED matrix driver. The
graphical user interface or GUI called LP586x GUI
is used to interface with USB2ANY to the EVM. The
EVM has SPI and I2C inputs through the USB2ANY
interface adapter.
Get Started
1. Order the EVM on ti.com
2. Request the LP5860T data sheet
3. Download the LP586xGUI from ti.com
4. Request the EVM design files

• Design resources for the LP5860TEVM The LP5860TEVM can be converted for testing the LP5868T and LP5866T, which are from the same device family, by removing the factory-installed device (U1) and replacing with the LP5868T or LP5866T counterpart. When testing the LP5868T or LP5866T device, select the corresponding tag from the menu on the GUI start page to start evaluation. -

Hardware 2 Hardware This following chapters describe how to set up the LP5860TEVM properly. Items from the following list are required to begin evaluating the LP5860T: • Computer • LP5860TEVM • USB2ANY interface adapter 2.1 Hardware Setup In the default jumper setting, the board can be evaluated by USB power directly and does not need an external power supply. - Page 4 If maximum current is set above 20 mA, an external VLED supply is recommended during evaluation, since the USB can only provide around 400-mA current. The setup procedure follows: 1. Connect the USB2ANY to the LP5860TEVM using the 30-pin ribbon cable. 2. Connect a 5-V external power supply to the VLED_EXT terminal (see...
