# PCB for current/power measurement of MSP430FR5994
+ Modified design from TI's MSP430FR5994 Launchpad
+ removed emulation unit, power supply etc
+ added current sense amplifier (Gain: 200, BW: 100 kHz) between mcu and main decoupling capacitor
+ added load switch that turns controls supply to mcu
+ decoupled mcu from main VCC
+ reduced layout from 4 to 2 layers
This is a simple 2 layer PCB made for high frequency ($\approx100\ kHz$) current measurement of the MSP430FR6994 microcontroller.
The main purpose is to measure current going between the MCU and its decoupling capacitance, with high enough bandwidth to capture behaviour on an intermittent supply.
The board does not currently include supply voltage supervision circuitry to turn on and off the included load switch (that controlls the MUC's supply voltage).
The load switch therefore has to be controlled by an external circuit, or connected via a jumper such that it's always on.
The board was based on the TI's MSP430FR5994 Launchpad board, with the folowing changes:
+ removed emulation unit, power supply etc
+ added current sense amplifier (Gain: 200, BW: 100 kHz) between mcu and main decoupling capacitor
+ added load switch that turns controls supply to mcu
