This Friday, a new Power Control Shield and headers for the ESP32 Thing, Thermal Gap Filler, and a few little bits and bobs.
Hello, and welcome back to another Friday Product Post! We have a powerful set of products this week, including a Power Control Shield and headers to attach to the popular ESP32 Thing. Additionally, we are happy to bring you 9"x9" sheets of Thermal Gap Filler, a mountable slide switch and half-H driver ICs. Without further ado, let’s dive in and see what we have!
With great power come great electricity bills.
The SparkFun ESP32 Thing Power Control Shield enables the ESP32 Thing to switch up to 5A of a DC load, providing a wide variety of options to control your next project! With a default voltage range of 5–28VDC, power can be connected to this shield in one of two ways. The first is the barrel connector, but with a maximum current rating of 2.5A (designed for light loads). The second option is on the 3-pin screw terminal, which has connections for VCC, ground and a 5V output. The supply voltage is regulated down to 5V to power the ESP32 Thing, as well as a fan to keep the board cool under heavy loads.
These headers are made to work with the SparkFun ESP32 Thing and ESP32 Power Control Shield boards. Each set of headers makes your ESP32 Thing easily stackable with the power control shield or other applications.
This Thermal Gap Filler provides 1.1W/mK of thermal conductivity that can conform to most surfaces. This gap filler is perfect for high-value products that you need to keep cool, as it is a poor conductor of electricity while remaining a great conductor of heat! No additional adhesive is required when applying the Thermal Gap Filler, as it is naturally tacky and sticks to whatever you need it to — just be sure that’s where you need it!
Now for some handy little parts! This is a mountable SPDT slide switch — great for use as a general control switch. The pins are spaced by 3.7mm (0.14"), making breadboard use not an option. The switch is rated for 300mA at 125VAC.
Last up today we have a little IC we previously used on our old RaspiRobot Boards. The L293DNE is a PTH quadruple, high-current, half-H driver IC. These ICs have been designed to provide bidirectional drive currents of up to 600mA at voltages from 4.5V to 36V. The L293DNE can drive inductive loads such as relays, solenoids, DC and bipolar stepping motors, as well as other high-current/high-voltage loads in positive supply applications.
And that’s it, folks! We hope you enjoy the offering this week. As always, we can’t wait to see what you make with these parts! Shoot us a tweet @sparkfun, or let us know on Instagram or Facebook. We’d love to see what projects you’ve made!
We’ll be back next Friday with even more new products! See you then.
