MCRY-PROTOKIT

MATRIX Mercury Boost Converter Prototype Kit MCRY-PROTOKIT The MATRIX Mercury Prototype Kit is a rapid prototyping platform built around the Mercury energy harvesting DESCRIPTION boost converter. It is ideal for developing IoT sensor applications that harness energy from very low temperature differences and eliminate the need to replace or recharge batteries. The board includes an ultra-low power 16- bit microcontroller (MCU) with Bluetooth Low Energy (BLE) that is pre-programmed with a beacon application. Connect the 2-pin terminal block on the board to a suitable power source, such as a thermoelectric generator (TEG). When power is supplied, the board begins harvesting energy and stores it in the onboard storage capacitors. The MCU sends a BLE beacon transmission whenever there is sufficient energy accumulated in the capacitors. An Android app is also provided as a basic framework for building customized apps. The board supports the addition of external hardware, and it has been optimized for low start-up voltage with a 50:1 turns ratio transformer that is on the board. Mercury features an 8-bit on-chip ADC that detects when the open circuit voltage VOC exceeds the programmed limit and turns off the input to ensure reliable operation. The outputs of the ADC are connected to the MCU to allow real-time measurements and transmission of the ADC output over BLE. The Prototype Kit is equipped with MCRY12-125Q-42DI, which is optimized for 12 input impedance, 12.5H inductor and 4.2V output. Please contact info matrixindustries.com for customization options.
