Technical and Functional Specifications

Nonintrusive

  • Plugs in-between any existing 3.3V MCU + shield solution without requiring any firmware changes

Compatible

  • Uses the widely popular Arduino connector layout and pinout

Bidirectional

  • Ability to measure both MCU and shield currents separately

High precision

  • Auto-switching shunt resistor bank for optimal range selection, accurate current-sense amplifier and 16-bit sampling depth

High speed

  • Optimized processing pipeline enables acquisition @ 88 kSa/s

LCD module

  • Embeds capacitive touch buttons and an LCD module to provide quick and easy access to a control menu

I²C sensor emulation

  • Can be accessed through a standard I²C interface and virtual register map

Bluetooth module header

  • Embeds a header for connecting an off-the-shelf UART-to-Bluetooth module

USB connector

  • Enables the creation of highly optimized communication channels using the USB stack, or through a virtual serial port
