USB PD Power Supply/Module ATS
8000 Series
The USB 3.1 specifications has three major features which are 10Gbit/s transmission speed, USB PD (Power Delivery) with support for 100 watt charging power, and the standard Type-C connector/cable that can be inserted with either side. It is expected to meet all kinds of data / video transfer applications. The advent of USB PD may consolidate the specifications of various power converters and the laptop, monitor, printer or Hub that implements USB PD is no longer a simple power-consuming device but able to supply power to other devices. The USB PD DRP (Dual role port) function allows the built-in USB PD module to deliver a maximum of 100 watts of power through the Type-C interface. To make sure the USB PD Type-C output power does not supply invalid voltage or poor power output characteristics with excessive noise that can damage the power consuming device and cause unsuccessful startup, each USB PD power supply or module has to be fully tested during production to ensure the product features meet the design specifications. This ensures high-quality products are provided to the market to gain acceptance.

Basic Quad J-Type Analog Thermocouple Amplifier
SEN-30103-J0
Analog thermocouple amplifier board based on the AD849x from Analog Devices (successor of the AD597). This quad-channel thermocouple board converts the very low voltage signal from a thermocouple to a highly-linear, 0.005V/C output with either 0V or 1.245V offset (both configurations stocked) while removing unwanted noise from the signal. Many supply and output configurations are available with this board, though the PCB was designed with Arduino in mind. Specifically, the output header will plug directly into a standard Arduino Uno or Mega, with a pin-for-pin match for power supply, ground and analog outputs. With a 5V Arduino, temperatures from 0C to 1,000C are possible with the 0V offset board and -249C to 750C with the 1.245V offset board. If using a 3.3V microcontroller (Due, etc), the board must be supplied with no more than 3.3V to avoid damaging the microcontroller. Temperature measurement range is dependent on the supply voltage. It is possible to supply the board with higher voltages to allow temperature measurement over the entire operating range of the K-Type and J-Type thermocouples, allowing use with more capable data acquisition equipment.
