New Product Roundup – January 15th to January 21th

Welcome back to another weekly New Product Roundup! This week we saw quite a few new parts added to the catalogue including everything needed to monitor your heart rate using an Arduino, a couple new cable connectors, a shaft coupler for our NEMA 23 stepper motor, and a new capacitor. No time to waste – let’s take a closer look!








SparkFun Single Lead Heart Rate Monitor – AD8232

The AD8232 SparkFun Single Lead Heart Rate Monitor is a cost-effective board used to measure the electrical activity of the heart. This electrical activity can be charted as an ECG or Electrocardiogram and output as an analog reading. To grab the data, you will require a set of Biomedical Sensor Pads and a Sensor Cable.

Biomedical Sensor Pad (10 Pack)

This is a 10 pack of Biomedical Sensor Pads, disposable electrodes that can be used to measure EEG, ECG and EMG levels. these little pads are perfect for short-term monitoring of Neurofeedback and Biofeedback. These will snap right on to our Sensor Cable.

Sensor Cable – Electrode Pads (3 Connector)

This is your simple three conductor sensor cable with electrode pad leads. The cable features a 3.5mm audio jack connector on one end with 3 individual 24″ wires complete with snap style receptacles for biomedical sensor pads. This is designed to work with the SparkFun Single Lead Heartrate Monitor and Biomedical Sensor Pads we carry.

Aluminum Flex Shaft Coupler – 0.250″ to 8mm

Shaft couplers are an important part of a CNC machine or drive system – they are designed to connect two drive shafts together. This specific version is designed to couple a 1/4” shaft to an 8mm shaft and is perfect for connecting our 125 oz-in stepper motor to 8mm diameter lead screws.

2 Pin AMP Superseal Connector – Pre-Wired

Good quality weatherproof connectors are sometimes quite hard to come by. These connectors come in several pin configurations and are designed to take the day to day abuse found in a dusty or wet environment. The secure locking tabs prevent wires from being pulled out of the connector and the connector from becoming disconnected. Over the coming days we will have 3, 4 and 6 pin versions of this connector available.

2 Wire Inline Connector

This two wire inline connector is the same one typically found in many radio control toys. The cable set includes both halves of the connector pre-terminated to 22AWG wires. Since this is typically used as a battery connector, it is keyed to prevent it from being reverse inserted.

470uF/25V Capacitor

And finally, we have an item that isn’t terribly exciting, but quite useful. We now stock a 470uF electrolytic capacitor to bridge that gap between 100uF an 1000uF. These are rated to 25V and have a 20% tolerance.
