The QCM electronics is a high-quality Arduino compatible shield for quartz crystal microbalance applications. The QCM shield is a dual layer PCB characterized by lead-free gold-plated pads. The QCM circuit consists of a quartz crystal oscillator driver, signal conditioning circuit and a new I2C temperature sensor with extended T range (-40°C to +125°C), which improves the signal quality of the crystal oscillator. The electronic circuit is optimized for use in crystal oscillator applications for quartz sensors at 10 MHz and also in the range of frequencies, from 1 MHz to 6 MHz. It is designed to minimize the electric power consumption.
The QCM electronics is designed as a shield for Arduino Micro microcontroller board.
