2.7 How can an external sensor be connected on the RF430FRL152HEVM?

The following sensors can be connected to this EVM.

  • I2C or SPI sensor: see Section 3.2.2 for an example
  • Thermistor: see Table 5 for connections
  • Analog sensor: see Table 5 for connections

All three of these signals are routed to the not-populated SV16 header. To use any of these ADC inputs for an external sensor, one of the components in Table 5 must be removed.

Table 5. Sensor Connections

ADC Input SV16 Pin
(Connect Sensor Here)		 Remove
ADC0 3 R16
ADC1/TEMP1 1 R4
ADC2/TEMP2 2 R3
Ground 4 –

Sensors should be grounded to SVSS, especially if virtual ground is chosen (SD14CTL0: VIRTGND = 0). For more information on virtual ground, see the SVSS generator section in the RF430FRL15xH family technical reference manual.
