A board that connects electronic components.
PCB
Programmable Peripheral Interconnect (PPI)
Enables peripherals to interact autonomously with each other using tasks and events
independent of the CPU.
PPI
Right Hand Circular Polarization (RHCP)
Circular polarization in which the electric field vector rotates in a right-hand sense
with respect to the direction of propagation.
RHCP
