This is the control board for the 3pi+ 32U4 robot, and it is included as part of the Standard Edition, Turtle Edition, and Hyper Edition 3pi+ 32U4 kits and robots. It can be used as a replacement part for those products, or it can be assembled with the 3pi+ Chassis Kit and a pair of 6V Micro Metal Gearmotors with extended motor shafts to create a “custom edition” 3pi+ 32U4 robot.

This kit gives you the structural pieces you need to build your own 3pi+ robot. The chassis includes an integrated ball caster and battery holder for four AAA cells, a pair of 32×7 mm wheels with silicone tires, a bumper skirt, and motor clips that can be used to hold in the gear motors for operation without the bumper skirt. The chassis is designed to work with our Micro Metal Gearmotors, and you can add a 3pi+ 32U4 Control Board or your own electronics to complete your robot. Motors and electronics are not included.

This simple board serves as an adapter between a JST SH-style 6-pin male connector and breadboard-compatible 0.1″-pitch through holes. It works with our assortment of 6-pin female JST SH-style cables and can be used to more easily access the pins of our Micro Metal Gearmotor Encoders with top-entry and side-entry connectors. The silkscreen on the bottom side of the board is labeled with this specific application in mind, indicating which pin on the breakout board would correspond to which pin on the encoder.

This product is a 3-pack of breakout boards with side-entry connectors that are optically inspected but not electrically tested.

This USB-to-serial adapter lets you easily connect a TTL serial device to a PC by acting as a virtual serial port. The board is a Micro-USB carrier for the Silicon Labs CP2102N USB-to-UART bridge that provides access to all of its control signal pins and GPIO pins.

This tiny voltage inverter generates a negative output voltage corresponding to the voltage provided on its input, which can be from 1.8 V to 5.3 V. The compact (0.3″ × 0.35″) module has a typical efficiency of over 80% and can deliver up to 60 mA continuously.

This simple board breaks out the power, USB 2.0 data, configuration, and sideband pins of a USB Type-C connector to a 0.1″ spacing that is compatible with standard perfboards, solderless breadboards, and 0.1″ connectors. On-board CC pull-down resistors make it easy to use the receptacle in a power-sinking application.

This sensor is a carrier/breakout board for ST’s VL53L3CX laser-ranging sensor, which offers fast and accurate ranging up to 5 m. It uses the time of flight (ToF) of invisible, eye-safe laser pulses to measure absolute distances to multiple targets simultaneously, independent of ambient lighting conditions and target characteristics like color, shape, and texture (though these things will affect the maximum range). Distance measurements can be read through a digital I²C interface. The board includes a 2.8 V linear regulator and level-shifters that allow it to work over an input voltage range of 2.6 V to 5.5 V, and the 0.1″ pin spacing makes it easy to use with standard solderless breadboards and 0.1″ perfboards. Note: This is not recommended for use with 8-bit MCUs; for such applications, consider the VL53L1X or VL53L0X carrier.

This board is a 3-channel time-of-flight proximity and distance sensor module based on the OPT3101 IC from Texas Instruments. It emits infrared light in one of three selectable directions with its six integrated LEDs and measures distance by measuring the time delay of the reflected signal. Distance measurements can be read through a digital I²C interface. The combined field of view of the three sensing zones is almost 180 degrees, and the maximum range is about one meter. This module does not include any headers; we carry an alternate version with headers soldered.

The VClamp allows RoboClaw and MCP motor controllers to be used with switching power supplies by dissipating excess regenerative energy through a connected external resistor (not included). The VClamp connects directly to the motor power supply and gets logic power and signals from the RoboClaw or MCP controller. The clamping voltage is set in the Basicmicro Motion Studio software, and the board can handle peak voltages and currents up to 60 V and 60 A. A status LED lets you know when the voltage is being clamped.

This item is a stock Texas Instruments MSP432 LaunchPad that we unpackaged and to which we manually soldered the two connectors needed for use with the TI-RSLK MAX robot kit. Please note that a similarly configured LaunchPad is included in the full TI-RSLK MAX kit as sold by Texas Instruments.

These magnetic discs can be used with our 20D mm metal gearmotors (extended motor shaft versions only) as part of a quadrature encoder system that offers 12 counts per revolution. They are 2 mm thick with an outer diameter of 9.7 mm and an inner diameter of 2.0 mm. Appropriate Hall Effect sensors, such as those in our magnetic encoder pair kit for 20D mm gearmotors, are required to complete the system. These discs are bulk-packaged and must be ordered in multiples of five.
