Transistor Testing
Radiant is introducing an I2C digital-to-analog converter product that can be attached to the Precision Premier II and is controlled from Vision. The addition of this extra voltage source makes it possible for the Premier II to measure the performance of thin-ferroelectric-film gate transistors (TFFTs and MFSFETs). This document explains the theory for such testing and gives examples of such tests using Radiant's SFRAM transistors as examples.

Single-Channel Voltage Output D/A Converters
Analog Devices offers a broad portfolio of single-channel voltage D/A converters, which includes many leading products in performance and package size, with resolutions from 8-bit to 20-bit, low power, and a serial SPI, parallel, or I2C interface. Within the industry’s smallest packages, we offer more functionality within smaller board and module sizes. The integration of a precision reference minimizes board area and costs, eliminates the need of calibration, and reduces the number of external components to simplify the design stage.

Si1145 UV / Ambient Light / Proximity Sensor
SEN-36002
SEN-36002 is a highly integrated carrier board designed for the Si1145 UV, Ambient Light and Proximity sensor IC from Silicon Labs. This sensor has 100mLUX resolution, and has a dynamic range of 1 LUX to 128 kLUX with IR correction. This means that whether your application is indoors in poor lighting conditions or outside in full sunlight, this sensor has you covered. In addition, we added a high power LED (150mA max, 20 degree) to take full advantage of the proximity sensing capability of this IC - something you won't see on most competitive carrier boards. Integration is easy with 4 x 4-40 sized mounting holes at the corners of the PCB and signal translation to handle interface voltages from 3V to 5V. The board is interfaced via an I2C interface and function pins have been broken out to a 0.1" pin header. The INT pin is also broken out for interrupt capability.

ArgoBot Kit
ROB-00001
The ArgoBot Full Kit is a fully assembled robot and controls development platform. It is based on the Digilent chipKIT WF32(TM), a WiFi enabled development platform, and configured for LabVIEW targeting. Most importantly ArgoBot was designed with FIRST Robotics Competition teams in the front of our minds! Named after the FRC Team 1756 mascot, Argos, the ArgoBot development platform includes a fully-assembled, ready to drive mini WiFi enabled robot (about 8" x 5" x 4"), as well as tons of FRC controls tutorials and example code (LabVIEW VIs). Features included on the ArgoBot will look very familiar to anyone who has worked with National Instruments products (Compact RIO and RoboRIO) in the past. This includes three 5V Digital I/O modules (with jumpered pull-ups), three 5V analog inputs, and an I2C header. Example VIs have been streamlined to enable a 1-click configuration style to accelerate your development process. We also added a 2-channel motor driver that is used to supply the ArgoBot drive motors. Our ultimate goal is that everything you can build, control or implement on ArgoBot can be easily leveraged on your FRC bot! Complimenting its many electrical features, ArgoBot is easy to work with and easy to maintain. The chassis is a polycarbonate (the extremely tough stuff that is easy to drill and modify but easily takes bumps and bruises without cracking) case that is fully intact - meaning that ArgoBot doesn't just come with a case... it is a case! Clean-up and organization is simple - just close the case and turn off the power switch.
