Hardware Hookup

For the purpose of this tutorial, we will be using a 5V Arduino. A microcontroller and logic level converter is required in order to read the sensor values through the serial UART pins. Make sure to solder the male header pins to the converter before making the connections on a breadboard. Begin by making a connection from an Arduino's high side and following the connection to the TFMini. Then continue to make the rest of the connections by following the hookup table listed below.

5V Arduino w/ Atmega328P Logic Level Converter (High Side) Logic Level Converter (Low Side) TFMini
Software Serial RX
(Pin 10)
HV1 LV1 UART_TX (3.3V TTL)
(Pin 1)
Software Serial TX
(Pin 11)
HV4 LV4 UART_RX (3.3V TTL)
(Pin 2)
3.3V LV
5V HV Vin (4.5V-6V)
(Pin 3)
GND GND GND GND
(Pin 4)

Once we are finished, it should look like the image below.
