Hi Angela, By no means do you need to buy a BoosterPack in order to use the SPI module, only a physical connection to the eUSCI peripheral pins used is required. Your options are to either create an ADS1299 EVM that includes header which can connect to the MSP-EXP430FR5994 or include the MSP430FR5594 on the custom ADS1299 board and layout the proper traces accordingly. The latter is more typical of a final product but requires additional circuitry to power and program the MSP430FR5994 , the former symbolizes more of a prototype but reduces circuitry required for the ADS1299 PCB. You will not be able to avoid this issue regardless of the LaunchPad variant considered. Regards, Ryan
