HT PB300 – Processor Board


The PB300 is a high temperature processor board with comprehensive features, including GPIO pins, analog bridge sensor interface, open drain outputs, on board accelerometer and high temperature flash memory.

Due to its small size, rugged construction and with a wide range of peripherals, PB300 is ideal as the main controller for downhole and drilling tools. NSE can provide the processor board with customer specified firmware or can assist if the customer want to create its own tool specific firmware.
