Function
Description
J3
SPI control from the
LEDMCUEVM-132
J2 and J3 allow attachment for SPI control of the TPS92520-Q1 to the TI LED MCU, part
number LEDMCUEVM-132. J3 is connected to the LEDMCUEVM-132. J2 is connected
other EVMs used in star or daisy chain configurations.
J2
J9
Additional control signals to
EVM
J9 and J5 are CAN, UART, GPIO, PWM, and SSN5 signals that come form
LEDMCUEVM-132 by J9 and are passed through to other EVMs by J5.
J5
J1
VIN1 and VIN2 connections
J1 configures how VIN1 and VIN2 are connected to each other or to VIN. No jumpers
separates VIN1, VIN2, and VIN. A jumper from pins 2 to 4 connects VIN1 to VIN2. Jumpers
from pin 1 to 2 and pin 3 to 4 connect VIN1, VIN2, and VIN all together (this is the default
configuration)
J6
SPI configuration
J6 allow for the ability to setup the hardware into a daisy chain configuration with both a
middle device and end device in the chain. The default configuration is a star configuration
(pin 1 and 3 are jumpered and pin 2 and 4 are jumpered) where all devices are controlled by
an independent SSN signals and must be selected based on J4 settings.
J10
V_REG jumper
J10 is a jumper provided to share VREG from LEDMCUEVM-132 with other SPI controlled
EVM, in case a digital supply is needed by the EVM, leave this jumper open because an
onboard supply is provided on this EVM.
