X-NUCLEO-LED16A1

X-NUCLEO-LED16A1 16 channel LED driver expansion board based on LED1642GW for STM32 Nucleo Data brief      Error detection  Open LED  Shorted LED Thermal shutdown Compatible with STM32 Nucleo board Equipped with Arduino™ UNO R3 connector RoHS compliant Description The X-NUCLEO-LED16A1 is an STM32 Nucleo expansion board designed to provide an application for the 16 channel LED driver LED1642GW. Multiple drivers can also be cascaded by coupling X-NUCLEO-LED16A1 expansion boards. Depending upon the end application, RGB or single color LEDs can be connected to the board. Separate brightness control is possible for each channel. It is compatible with the STM32 Nucleo board family and equipped the Arduino™ UNO R3 connector layout. Features       16 constant current output channels Output current: from 3 mA to 40 mA 20 V current generator rated voltage Provision for cascading multiple expansion boards Current adjustment:  7-bit global current gain adjustment in two ranges  Current programmable through external resistor  12/16-bit PWM grayscale brightness control Selectable LED Bus voltage supply  USB  Vexternal December 2016 DocID029773 Rev 1 For further information contact your local STMicroelectronics sales office 1/5 www.st.com 2/5 0 2 3 4 5 6 7 8 9 10 11 12 25 2 1 R24 Vdd R-EXT SDO PW CLK OUT15 OUT14 OUT13 OUT12 OUT11 OUT10 OUT9 OUT8 24 23 22 21 20 19 18 17 16 15 14 13 SDO PWCLK LED 16-K LED 15-K LED 14-K LED 13-K LED 12-K LED 11-K LED 10-K LED 9-K R1 +3V3 11K +5V 1 3 J4 2 DocID029773 Rev 1 1 2 3 CON3 J2 Indication LED's D2 GREEN LED FAULT D1 RED LED R4 470E R3 +3V3 560E 0 Daisy Chain Select Connectors NORMAL OPERATION J2: 1:2 SDI SIGNAL FROM MCU DAISY CHAIN J2: 2:3 SDI SIGNAL FROM SDO CN 1 FROM MCU SDI SDI DAISY CH AIN SDI-SDO CN 2 0 R7 R8 R9 R10 R11 R12 R13 R14 R15 R16 R17 R18 R19 R20 R21 R22 0 C4 10uF 1 2 3 CON3 J3 CN 4 LED Anode Conne ctor NORMAL OPERATION J3: 1:2 SDO SIGNAL TO MCU DAISY CHAIN J3: 2:3 SDO SIGNAL TO SDI CN 11 1-K 2-K 3-K 4-K 5-K 6-K 7-K 8-K 9-K 10-K 11-K 12-K 13-K 14-K 15-K 16-K 33E 15E 15E 33E 15E 15E 33E 15E 15E 33E 15E 15E 33E 15E 15E 15E LED Strip Header LED LED LED LED LED LED LED LED LED LED LED LED LED LED LED LED TO MCU SDO SDO DAISY CH AIN SDO-SDI 1:2 +5V USB CON3 2:3 External Voltage LED Rail Voltage Connector 0 D3 STPS 1L30 0E LED1642 GWXTT R (TSSOP24 e xposed pad) GND SDI CLK LE OUT0 OUT1 OUT2 OUT3 OUT4 OUT5 OUT6 OUT7 EP U1 I/P Conne ctor CN 3 LED Driver SDI SCK LE LED 1-K LED 2-K LED 3-K LED 4-K LED 5-K LED 6-K LED 7-K LED 8-K 0 1 C1 100nF C2 10uF CN5 CON16 8 7 6 5 4 3 2 1 10 9 8 7 6 5 4 3 2 1 2 4 6 8 10 12 14 16 18 20 22 24 26 28 30 32 34 36 38 R36 0E 0E 0E R23 R38 0E 0E 0E DN M R5 R25 R26 GND R27 LE PWCLK LED CONTROL 0 R37 LE 0 C3 100nF GND 0E 0E 0E +3V3 CN 10 1 3 5 7 9 11 13 15 17 19 21 23 25 27 29 31 33 35 37 +5V GND GND DN M R2 0R 0E 0E R30 0E R33 R34 R35 R31 +3V3 R39 PWCLK LED CONTROL SCK TO MCU SDO FROM MCU SDI LE SCK LE TO MCU SDO FROM MCU SDI +3V3 +5V +3V3 GND ST morpho Connectors GND CN 7 1 3 5 7 9 11 13 15 17 19 21 23 25 27 29 31 33 35 37 ARDUINO UNO R3 Connectors D7 D6 D5 D4 D3 D2 D1 D0 CN9 D15 D14 VDD GND SCK/D13 MISO/D12 MOSI/D11 D10 D9 D8 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 J1 1 2 3 4 5 6 1 2 3 4 5 6 7 8 CN 8 CN 6 GND A0 A1 A2 A3 A4 A5 NC IOREF RESET +3V3 +5V GND GND VIN 2 4 6 8 10 12 14 16 18 20 22 24 26 28 30 32 34 36 38 1 LED CONTROL Schematic diagrams X-NUCLEO-LED16A1 Schematic diagrams Figure 1: X-NUCLEO-LED16A1 circuit schematic (1 of 2) GSPG2309160945SG X-NUCLEO-LED16A1 Schematic diagrams Figure 2: X-NUCLEO-LED16A1 circuit schematic (2 of 2) D1 D3 1 2 3 4 LED RAIL VOLTAGE LED1_B LED1_R LED1_G LED1 1 2 3 4 LED RAIL VOLTAGE LED3_B LED3_R LED3_G 1 2 3 4 LED RAIL VOLTAGE LED4_B LED4_R LED4_G LED3 D2 D4 1 2 3 4 LED RAIL VOLTAGE LED2_B LED2_R LED2_G LED2 LED4 RGB LED's D5 1 2 3 4 J5 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 LED5 CN5 CON2 1 2 LED1_R LED1_G LED1_B LED2_R LED2_G LED2_B LED3_R LED3_G LED3_B LED4_R LED4_G LED4_B LED5_R LED5_G LED5_B LED RAIL VOLTAGE LED5_B LED5_R LED5_G LED RAIL VOLTAGE CON16 LED RAIL VOLTAGE RGB LED 's CATHODE FEMALE HEADER GSPG2309161015SG DocID029773 Rev 1 3/5 Revision history 2 X-NUCLEO-LED16A1 Revision history Table 1: Document revision history 4/5 Date Version 02-Dec-2016 1 Changes Initial release.
