The PGA309EVM-USB is an evaluation module that is used to fully evaluate the PGA309. The PGA309 is an integrated circuit that provides temperature compensation and linearization for bridge sensors. The PGA309EVM-USB consists of two PCBs. One board (the USB-DAQ-Platform) generates the digital signals required to communicate with the PGA309. The other board (the PGA309_Test_Board) contains the PGA309 device, as well as support and configuration circuitry.

Throughout this document, the abbreviation EVM and the term evaluation module are synonymous with the PGA309EVM-USB.
