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.

Silicon Oscillators
-
Analog Devices silicon oscillators are frequency programmable via pin-strapping, or through the resistor connection or serial interface (SPI or I2C). These solid-state clocks are well-suited for general-purpose usage, such as PGAs, ASICS, microprocessors, or UARTS, and they operate from 1 kHz to 170 MHz. Silicon oscillators are also ideal switching regulator clocks as they provide synchronization and EMI reduction (via spread spectrum).

The MCP9600 Breakout is a high accuracy Thermocouple Amplifier equipped with an I2C interface, accessed over our Qwiic system. Inside the chip are two temperature sensors, one for the thermocouple itself (the hot junction) and one for the chip itself (the cold junction). As a result, the MCP9600 can read both the ambient temperature and the temperature of whatever you're trying to measure! The MCP9600 can do both with a resolution of 0.0625°C, and an accuracy of ±1.5°C (worst-case). The MCP9600 Thermocouple Amplifier is one of our many Qwiic compatible boards! Simply plug and go. No soldering, no figuring out which is SDA or SCL, and no voltage regulation or translation required!
