The LOCOSYS LC20031-V2 integrates a global navigation satellite system (GNSS) receiver with an embedded antenna to create a complete GNSS module that can track up to 135 signals at a time from GPS and many other satellite systems, with support for both L1 and L5 bands. It can provide updates at up to 10 Hz, has a built-in rechargeable battery for rapid satellite acquisition (external power is still required for normal operation), and outputs data as NMEA sentences through a 3.3 V or 5 V TTL-level serial port.

The LOCOSYS LS20031 GPS receiver integrates a MediaTek MT3339 66-channel GPS chip with a ceramic antenna to create a complete GPS module that can track up to 66 GPS satellites at a time. The GPS module supports up to a 10Hz update rate, a built-in rechargeable battery for rapid satellite acquisition (external power is still required for normal operation), and more than 6 different NMEA ASCII sentences that are output to a 3.3 V TTL-level serial port.

The Vishay TSOP38438 is a general-purpose modulated IR receiver for IR-based remote-control projects. It features a wide operating voltage range of 2.5 V to 5.5 V; this particular unit is tuned for a 38 kHz carrier frequency.

The Vishay TSOP34156 is a general-purpose modulated IR receiver for IR-based remote-control projects. It features a wide operating voltage range and allows for relatively high data rates; this particular unit is tuned for a 56 kHz carrier frequency. This is the IR receiver used in the Pololu IR Beacon.

The Pololu IR beacon is a compact board that is used in pairs to allow robots to locate each other. Each board has infrared emitters that shine in all directions and four IR receivers for detecting the other beacon. The IR beacons have a range of about fifteen feet indoors. This item is for a pair of beacons in one package.

This item is for a single unit.

This single-pole, double-throw (SPDT) momentary switch can be used as a general-purpose micro switch, but the long lever arm makes it especially useful as a tactile bump sensor for your robot (e.g whiskers or antennae). The switch body dimension is 20.0 x 6.4 x 10.2 mm, and the lever arm is 50 mm long.

This single-pole, double-throw (SPDT) momentary switch can be used as a general-purpose micro switch or tactile bump sensor for your robot. The switch body dimension is 20.0 x 6.4 x 10.2 mm, and the lever arm is 16.7 mm long.

This single-pole, double-throw (SPDT) momentary switch can be used as a general-purpose micro switch or tactile bump sensor for your robot. The switch body dimension is 20.0 x 6.4 x 10.2 mm, and the 16.3mm lever arm is has a roller at the tip.

This single-pole, double-throw (SPDT) momentary switch can be used as a general-purpose micro switch or tactile bump sensor for your robot. The switch body dimension is 19.8 x 6.4 x 10.2 mm, and the 18.5 mm lever arm has a semicircular bump at the tip that simulates a roller.

This miniature single-pole, double-throw (SPDT) momentary switch can be used as a general-purpose micro switch or as a small tactile bump sensor for your robot. The switch body dimension is 12.8 × 6.0 × 6.5 mm, and the lever arm is 13.5 mm long.

This carrier board is designed to work with any of the MQ-series gas sensors, simplifying the interface from 6 to 3 pins—ground, power and analog voltage output—that are broken out with a 0.1" spacing, making the board compatible with 0.1" headers and standard breadboards and perfboards. This board has two mounting holes and provides convenient pads for mounting the gas sensor’s required sensitivity-setting resistor.
