Many products are now becoming connected through the Internet of Things (IoT), including test equipment such as digital multimeters (DMM).  Enabled by Texas Instruments’ SimpleLink™ ultra-low power wireless microcontroller (MCU) platform, the TIDA-01012 reference design demonstrates a connected, 4½ Digit, 100kHz true RMS, DMM with Bluetooth® low energy connectivity, NFC Bluetooth pairing, and an Automatic Wake-Up feature enabled by TI’s CapTIvate™ technology.


  • 4 1/2 digit, 50K count resolution
  • Wireless MCU enabling bluetooth low energy (BLE) for IoT wireless
  • Automatic wake-up enabled by CapTIvate capacitive touch technology
  • Low power design and power management systems
  • BLE mobile app pairing enabled by NFC dynamic interface
  • Firmware-based true RMS measurements
