3 / 14 page www.ti.com Setup 1.6.2 Power Supply (*Optional) To ensure correct functionality of the LEDs a 5V supply at 300mA is recommended (refer to note in section 2.3.1). If not using a USB cable to power the LaunchPad a 3.3V power supply at 200mA is required. 2 Setup This section describes the jumpers and connectors on the EVM. 2.1 Connectors and Jumpers 2.1.1 J1 & J2 – LaunchPad Headers These connectors mate with the male headers on the LaunchPad. 2.1.2 J3 – External LED Power This connector is where the external +5V supply is attached to power the two RGB LEDs. 2.1.3 J4 – TCA7408 GPIO This is a pin out of the four unused GPIO pins from the TCA7408, GPIO4-GPIO7. 2.1.4 J5 – Feedback loop For the TPL0401A to function as a voltage reference circuit the negative feedback loop must be shorted, placing a jumper across this header will short the inverting input to the output. 2.1.5 J6 – LED or Op-amp This header controls what the TPL0401B is attached to. When shorted across position 1 and 2 the TPL0401B is connected in series with the external resistor to control the current through the LED driver. When shorted across position 2 and 3 the TPL0401B is connected to the inverting input of the op-amp to change the gain of the circuit. 2.1.6 J7 – Op-amp input This header controls the input to the non-inverting pin of the LMV321. When shorted across position 1 and 2, the TPL0401A in a voltage divider mode is attached to the non-inverting input of the LVM321. This setup is used to test the voltage reference setup. When shorted across pins 2 and 3, the SMA connector is attached to the non-inverting input. 2.1.7 J9 – Test Points This connector offers test points for the serial data lines, SDA, SCL and the DIN that drives the TCA5405.
