Thermostat Implementation with MSP430 Microcontroller Reference Design

TIDM-FRAM-THERMOSTAT

Design files

Overview

This reference design, featuring the MSP430FR4133 MCU, is for a battery-powered thermostat with an RS-485 remote control. The design provides accurate temperature measurement, a 3.4 inch LCD and extended battery life through ultra-low power operation.  

Features
  • 0°C - 35°C temperature measurement with 0.1°C resolution
  • Ultra-low power: 1.8uA standby current
  • Capacitive touch buttons available
  • 20-pin BoosterPack™ module headers to add connectivity
  • GUI for RS-485 remote control
