115XOPT-EXP-EVB Silicon Labs

UG163: Si1133/Si115x Optical Sensor Evaluation Board Rev 3.0 User s Guide This board can be ordered as part number115xOPT-EXP-EV. The optical sensor ex- pansion board is designed to allow customers to evaluate the Si1133 UV/ALS sensor KEY FEATURES and other Si115x series sensors. A list of these sensors and their capabilities follows: UV/ALS Sensor UV/ALSSi1133 sensor mounted with a demonstration light diffuser assembly. Long-Range Proximity Sensor Long Range ProximitySi1153-AB09 2 x 2 mm proximity sensing chip with an on- Sunlight-Immune Proximity Module Sensor die 940 nm bandpass filter for sunlight immunity. The board demonstrates the use of a 5 mm dia. lens and narrow-angle LED. Gesture/ALS Sensor Sunlight Immune Proximity ModuleSi1153-AB9X, 2.85 x 4.9 mm proximity sens- Compatible with Silicon Labs EFM EVBs and Optical Sensors Programmer Toolkit ing module with an on-die 940 nm bandpass filter for sunlight immunity and an inte- grated 940 nm LED. Simplicity Studio compatible Proximity/ALSSi1153-AB00, 2 x 2 mm light sensor chip. The board uses a single 850 nm LED for demonstration purposes. Gesture/ALSSi1153-AB00, 2 x 2 mm light sensor chip. The board uses three 850 nm LEDs spaced roughly 50 mm apart for demonstration purposes. The optical sensor expansion board is designed to allow customers to connect to the sensors using two methods: Silicon Labs EFM series of EVBs with an expansion ports. e.g. the EFM32 Pearl Gecko PG12 Starter Kit: EFM32PG12 (SLSTK3402A) USB connectivity via the Optical Sensors Programmers Toolkit The EVB comes with a plastic overlay that simulates a customers product and covers most of the sensors.
