Boardoza TMCS1101A2UQDRQ1 Current and Temperature Monitoring Breakout Board
This board is a compact measurement module designed for monitoring current and temperature in embedded systems. It features the TMCS1101A2UQDRQ1 Hall-effect current sensor and a TMP235 analog temperature sensor, both providing analog voltage outputs. These signals can be read either as analog voltages or through I2C connected ADCs (U3 and U4), depending on the system configuration.A digital mode is set as default, enabling direct communication with a microcontroller via I2C. However, by changing routing options, the board can also operate in analog mode, allowing flexible integration in a wide range of applications. Additionally, a power LED indicator ensures visual confirmation when the system is powered. Perfect for real-time current and temperature monitoring, this board offers both versatility and precision.
