About this document
Scope and purpose
The TLD7002-16SHIELD is an LED driver shield compatible with Arduino UNO. The TLD7002-16ES is a 16
independent-channel-LED driver with individual output current from 5 mA to 76 mA and UART over CAN
interface.
The scope of this user manual is to provide instructions on use of the TLD7002-16SHIELD for a jump-start on the
TLD7002-16ES programming with the simple Arduino IDE.
This user guide describes the TLD7002-16SHIELD with PCB version P03 and P04 in which, only thermal vias are
changed. Additionally, schematic version S03 is described.
This board will be used during design-in, for evaluation and proof of concepts for new projects adopting the
TLD7002-16ES.

TX and RX connected to TLD7002-16ES UART. The soft serial library has been slightly modified in order to handle the 230 kbps with reduced delay on adjacent bytes. The Arduino UNO can be programmed even if the TLD7002-16SHIELD is plugged into the Arduino. TLD7002-16ES Power supply options The TLD7002-16ES applications has 2 supply rails: •... - Page 5 VS_REV Figure 4 TLD7002-16SHIELD power supply connections with Arduino UNO R3 The TLD7002-16ES output currents can be as high as 76.5 mA per channel, for a total current of 1224 mA in case all outputs are on @100% duty. The current setting on the TLD7002-16ES outputs must be adjusted in order to avoid damages to the Arduino UNO circuitry.

Page 6: Quick Start Procedure
TLD7002-16SHIELD plugged in the Arduino UNO with USB cable The TLD7002-16SHIELD is equipped with efficient white LEDs, therefore in order to keep the glare low, a duty cycle is set to 10% on the TLD7002-16DEMO sketch V.1.0. The brightness can be easily increased by modifying the provided sketch. - Page 7 Then search for OTP Wizard (point 1) and click on Install (point 2).
