I2C to 8-Channel Solenoid Driver
·
This driver board makes it much easier to control multiple solenoids from a microcontroller over I2C. It uses an MCP23017 GPIO expander so you do not need to dedicate lots of pins just to switch a bank of clicky, inductive loads.Solenoid power connects through the centre terminal blocks, with eac...
Adafruit STEMMA Soil Sensor - I2C Capacitive Moisture Sensor
·
The Adafruit STEMMA Soil Sensor uses capacitive measurement to detect soil moisture — a more durable approach than resistive sensors that corrode over time. With a single probe and no exposed metal, it avoids oxidation issues and won't introduce DC currents into your plants. The ATSAMD10 microco...
Flexible Qwiic to STEMMA Cable - 500mm
With the SparkFun Qwiic Connect System expanding every day, we want to make sure it becomes as accessible as possible but we understand there are other systems that can compliment it out there. The Qwiic to STEMMA Adapter Cable allows interoperability between the SparkFun Qwiic Connect System and...

Adafruit MCP2221A Breakout - General Purpose USB to GPIO ADC I2C - Stemma QT / Qwiic
·
The Adafruit MCP2221A Breakout lets your computer talk directly to I2C devices, sensors, and GPIO — no microcontroller required. Drive an OLED display, read a colour sensor, flash LEDs, or read buttons straight from Python on Mac, Windows, or Linux. The MCP2221A from Microchip provides USB-to-I2...
Maker Pi Pico Base - Raspberry Pi Pico Not Included
·
Cytron's Maker Pi Pico Base incorporates the most wanted Reset button for your Raspberry Pi Pico and gives you access to all GPIO pins on two 20-pin headers, with clear labels. Each GPIO is paired with an LED indicator for convenient code testing and troubleshooting. The bottom of the board even ...
JST PH 4-Pin to Female Socket Cable - I2C STEMMA Cable - 200mm
·
This cable will let you turn a JST PH 4-pin cable port into 3 individual wires with high-quality 0.1" female sockets on the end. We're carrying these to match up with any of our boards with 'STEMMA' connectors on them such as the Hallowing or Trellis M4. Can also be used with any STEMMA bre...
SparkFun Soil Moisture Sensor
The SparkFun Soil Moisture Sensor is a simple breakout for measuring the moisture in soil and similar materials. The soil moisture sensor is pretty straight forward to use. The two large exposed pads function as probes for the sensor, together acting as a variable resistor. The more water that is...
