Add quadrature encoders to your micro metal gearmotors (extended back shaft version required) with this kit consisting of two sensor boards, two 3-tooth encoder wheels, and two 5-tooth encoder wheels. The installed system does not exceed the 12 mm × 10 mm cross section of the motors and extends only 5 mm beyond the plastic motor end cap. The 3-tooth wheel provides 12 counts per revolution; using the 5-tooth wheel yields 20 counts per revolution. This version is intended for use at 3.3 V.

ESP32-S2 Saola-1 is a small-sized ESP32-S2 based development board produced by Espressif. Just about all of the I/O pins are broken out to the pin headers on both sides for easy interfacing. Developers can either connect peripherals with jumper wires or mount ESP32-S2 Saola-1 on a breadboard - Adafruit recommend two breadboards 'side-by-side' since the Saola is a bit wide and you won't have extra holes on one side for wiring.

Press to release pleasure! Our redesigned digital push buttons come with LED, immersion gold surface, and bright colored hats. A captital D at left corner indicates that it is a digital sensor. An illustration of button painted in the back notifying its function. Pressing it is a real fun, especially with the plastic cap off. The long pressable life also ensures its durability.

Here is a very simple breadboard power supply kit that takes power from a DC wall wart and outputs a selectable 5V or 3.3V regulated voltage. The .1" headers are mounted on the bottom of the PCB for simple insertion into a breadboard. Pins labeled VCC and GND plug directly into the power lines. The lone pair of pins have no electrical connection but help support the PCB.
